How easy it is to unscrew a rusty bolt when only improvised tools are at hand. Find out what to do if a bolt sticks

Facing a stubborn bolt? Here's what you need to do to unlock it...

Many novice auto repairers at the beginning of their careers, and even ordinary motorists and ordinary people who are fond of technology, sooner or later had a question dictated by cruel reality. What to do? Got hooked - and not from a place!

For professionals, such a logical question is solved quickly: more experienced workers will help them unscrew the stubborn bolt that breaks off the entire repair process, since experienced repairmen have more than one option for breaking off a problematic fastener. But what should ordinary people do in this case? There is a lot of rather contradictory and often ineffective information on the Internet. It looks like we found a good guide that not only tells, but also clearly shows how to overcome a stubborn threaded chip.

There is nothing super complicated in the operation of rescuing a stuck bolt (although we strongly advise NOT to use the methods described below on your own if you do not have the necessary skills), despite the fact that at first glance everything looks very difficult and intimidating. Nevertheless, a specific tool for a rescue operation will still come in handy. But first things first. The video shows two situations:

1. The end of the bolt rises above the surface of the part by an insufficient distance so that the first one can be picked up with pliers.

In this case, the master uses an autogenous cutting torch. We understand that if you do not repair cars or do not work in a car service, such a tool is unlikely to be on your balcony somewhere, but since the situation in question is a stalemate (either throw away a spare part or contact specialists), find a means of repair or knowledgeable people who will do everything for you, you still have to. We only demonstrate with this material that this is a completely working operation and with its help you can unscrew even the most neglected fastener.

What will be needed for work? , a brush with stiff wire bristles, an autogenous torch and safety equipment: goggles and heat-resistant gloves.

Disposition. A bolt fragment is stuck in the timing cover. The cover is made of aluminum, the bolt is made of steel. To release the stuck thread, it is necessary to expand the external material - aluminum - by heating. Since aluminum with the same volume heats up faster than steel, there will be no difficulties with this.

You will need to clean the bolt from dirt and oil. Put on protection: gloves and goggles, turn on the burner (if you don’t know how, we strongly DO NOT recommend using it yourself, contact the professionals) and direct the heat of the burner to aluminum. After about half a minute (we counted that the author of the video autogenated the body for 29 seconds), you can make the first attempt to move the bolt by rocking it from side to side. As soon as you give in, consider it in the bag. Twist until the aluminum is hot and allows you to remove the element without problems.

Caution - danger! The master warns that the cover of the distribution mechanism is aluminum, so it does not need to be heated very much and not for long. Since aluminum, unlike steel, does not change color when heated, you may not notice that it is overheated. As soon as this happens, gas bubbles may appear in the metal, which, bursting, can injure the worker with particles of hot metal flying in all directions.

Plus, too much heated metal will no longer hold its shape and the part will be irretrievably damaged.

The operation ends at 2.55 minutes of the video. unscrewed.

2. The next option also implies the presence of specific tools and skills to work with them. This time it's welding. Therefore, again, we strongly recommend that you turn to professionals if you do not know how to work with welding. And it is all the more unlikely that you have a welding machine at home, and buying a device for 15-30 thousand rubles and learning how to work on it to unscrew one bolt is rather strange.

If the bolt breaks off flush with the surface, as is usually the case, and it is impossible to pick it up with pliers, welding and a nut will come to the rescue. The essence of the process is shown from 3.30 minutes of the video.

In short, the theory goes like this: a nut is welded to a part of a bolt, during welding, the steel bolt and aluminum heat up. heats up a little more, expands also more than steel, releasing the thread.

Once the nut is welded to the bolt part, action must be taken. We throw on the key and, swinging from side to side, we release the problematic fasteners.

Bottom line: the thread is intact, the part is not damaged, they got rid of the broken bolt.

Video:

P.S. We gave as an example two exploratory ways of unscrewing problematic bolts. To unscrew the bolts at home, check out our following material:

Basically, each repair does not go smoothly, but with the occurrence of small problems, the elimination of which takes time and effort. What to do in a situation where you need to disassemble the structure, and the bolt is rusted or damaged, we will analyze further.

At home, not every master will have the necessary equipment at hand, but this problem can be dealt with with improvised means.

How to unscrew a broken bolt?

Main methods:

1. Clean the surface with a metal brush and treat with diesel fuel or kerosene. Trying to unscrew the nut with a wrench. Although there is no absolute guarantee that it will unscrew.
2. With the help of a chisel and a hammer, strikes in the direction of unscrewing. This method is not suitable for a small nut.
3. A gas wrench with a powerful clamp is a good tool in this situation. It is easy for them to grab even round objects, but heavier in hard-to-reach places. The longer the handle, the easier it is to unscrew operations.
4. When fasteners with a large size and it is difficult to unscrew it, it is possible to apply a metal coating using welding equipment and prepare the desired turnkey shape with a file.
5. A hole is cut with a drill inside the body of the fastener, an L-shaped rod is threaded through it, which will serve as a handle, and removed.

When there is enough space to use an adjustable wrench or pliers, this is good, but what to do in other situations?

How to unscrew a bolt with a hex or asterisk head

To extract an element use gas wrench with a compression of the part, they make a cut on the hat with a grinder and unscrew it with a screwdriver, an extractor of the appropriate size, special tools (a wrench, a stud driver), which are beneficial to purchase only if you have to deal with such problems quite often.

A TORX sprocket is selected in size (it should not be large and slots should go into the hole for the hexagon). It is inserted tightly into the cap and the bolt is unscrewed with a jerk to avoid breaking the sprocket slots. When driving stars with holes in the center, they break off, so it is not recommended to use them.

In any construction and auto shop extractor kits for sale. Outwardly, this device has the form of a metal rod with a conical thread on the left side and a faceted base on the right. With their help, unscrew the nuts with torn edges. To do this, a hole is drilled strictly in the center of the bolt, an extractor of the desired size is hammered into it and unscrewed with pliers. This is done simply and quickly, because the extractor has the opposite cut.

A drill with a reverse is an irreplaceable thing. Make a hole at the bolt with a thin drill. Take a left-hand drill with a smaller diameter and drill out the damaged bolt in reverse rotation mode.

If the bolt head is broken off

In this case, you need to be patient and choose the appropriate course of action.

Three ways:

1. A hole is drilled 3 cm smaller than the diameter of the bolt and a tap with a left-hand thread is screwed into it until the broken part begins to unscrew.
2. If part of the bolt protrudes, then a cut can be made on it with a grinder under a slotted screwdriver and proceed to unscrewing.
3. A hole is made in the base, into which the extractor is screwed counterclockwise. Then the damaged element is removed with a key.

The process takes a few minutes, but there are countersunk head products under the hexagon, the edges of which are easily torn off. Torx of a suitable size will help to cope with such a problem.

How to drill out a broken bolt

Professionals advise using a small diameter drill and making sure that it does not tilt to the sides when working. When buying, you need to focus on the country of origin and cost. High-quality drills cannot be cheap, sharpened in a special way and made of hardened steel.

Unscrewing nuts and bolts produce slowly and consistently, in this case it is impossible to rush, otherwise unforeseen problems will arise later and the loss of time to eliminate them. For example, many auto repairers are in a hurry to unscrew rusty bolts that break. It takes a lot of time to fix bugs. Therefore, it is necessary to plan the course of action immediately. How to deal with rusty bolts, we will discuss further.

How to loosen a stuck bolt

Often, car repair is complicated due to the presence of corrosion and oxidation of fasteners. For example, at the factory, during assembly, the master did not treat the thread with lubricants, and during operation water got into it. As a result, the bolt stuck, it would seem, tightly, but such a nuisance can be dealt with in several ways.

Loosen a rusted bolt or nut by tapping

When tapping with a bolt remove rust and scale, so it becomes easier to unscrew it. The operation is carried out with a hammer, turning with a special tool in order to create a torque. With caution, as you can damage the product and have to drill it. After removing the fastener, it is cleaned of rust and treated with graphite grease. If available, put anther on the connection.

With solvents

In the arsenal of any experienced car enthusiast there is always a set of liquids to combat rust and other plaque. Mostly use WD-40 with good penetrating ability into micro gaps, the cost of which starts from 100 rubles. Along with it, brake fluid, white spirit, kerosene, Coca-Cola are used. Unlike WD-40, other liquids have a weaker effect, and it is better to pour them into a container and place the boiled compound in it for greater effect.

If the bolt is stuck on the front pillar, the solvent can be carefully poured into the "glass". The main thing is not to damage the rubber bands on the racks, otherwise you will have to change them.

Moisten a rag with any means, wrap the nut and leave for a while. Then the bolt is tapped to destroy the softened rust and proceed to unscrewing.

thermal method

When the solvent does not do the job, you can try exposure to fire and cold. Any major auto or hardware store sells a gas burner that heats the bolt to a bright orange color. Then they cool it with engine oil and try to loosen it. If the attempt fails, the process is repeated anew.

This method does not always help, and when close to the paintwork, the fuel tank is very dangerous. When working with a gas burner, you must follow the fire safety rules and do not use it if you do not have a fire extinguisher at hand.

Freeze sprays are used to save the bolt for later use. But such reagents are mainly used by professionals, since in domestic conditions this business is costly and unprofitable.

How to unscrew a licked bolt

When scrolling the bolt, it is hooked with a nail puller and pulled out to the maximum possible height, left in tension and gradually unscrewed with a key. When a nail puller is not available, a screwdriver can be used. A small bolt is removed with wire cutters by the head. If it does not lend itself immediately, then rotate it, clamping it with pliers counterclockwise with an upward force.

Use tap, insert it all the way. If it is not at hand, then a screwdriver with a cone-shaped edge will do, which is carefully hammered all the way and they try to unscrew it.

To prevent such situations from recurring, they must be treated with graphite grease before tightening the bolts. But solid oil or lithol is not used for this purpose, because they are used for rubbing parts, and after lubrication, bolted joints are wedged.

How to unscrew the bolt? An article about effective ways with an overview of the tool, the best and non-standard.

In the material, we will consider how to unscrew a torn bolt (with torn edges), a rusted bolt, a crankshaft pulley bolt, a wheel, an exhaust manifold, a cylinder head and other components and assemblies.

How to loosen a bolt

Bolts are usually unscrewed with box or open-end wrenches, screwdrivers, heads using a wrench, ratchet or pneumatic wrench. However, other options are also possible.

Before unscrewing the bolt, from the available tool you need to choose the one that fits best:

• thin short open-end wrenches, especially with a too free (broken) pharynx, are the worst option, which is better to refuse immediately in a situation with unscrewing rusty stuck bolts (this will lead to torn edges);
• box wrenches are preferable to open-end wrenches, since they cover the perimeter of the bolt head more tightly;
• A 6-point ring wrench or head is preferred over their 12-point versions, since the hex keys have a larger area of ​​pressure on the flat working surfaces of the cap and are less likely to rip off the edges;
• a tool with an elongated handle or an additional nozzle is preferable to a short one;
• due to its simplicity and strength, a wrench is preferable to a ratchet, because for the latter, the application of increased forces can damage the mechanism (this is especially true for ratchets with a large number of teeth, each of which is smaller and not so strong);
• an impact wrench is better than a hand tool;
• in combination with a wrench or impact wrench, the best solution would be the Super Lock head, in which the force is applied not to the corners (faces), but to the planes, which eliminates the licking of the edges of the bolt head;
• moment amplifier (multiplier) will help to apply a force to a large stuck bolt that exceeds human physical capabilities;
• a screwdriver with a large handle of a typical shape or a T-shaped power driver will do a better job than traditional compact versions;
• a suitable clamping tool (pipe ("gas"), wrench, clamp, vise, pliers, etc.) will come in handy in the absence of keys or with licked edges;
• with sufficient head height, in rare cases, an appropriately sized stud driver can be used.

Further, when describing the methods, we will show how to unscrew the bolt from an atypical tool.

A durable Super Lock head for wheel bolts is worth purchasing and carrying with you in the car at all times, since wheel fasteners often get damaged during seasonal tire changes and can cause serious difficulties for the car owner on the road in the event of a puncture.

Which way to unscrew the bolt

Most often, bolts with the right thread direction are used: they need to be unscrewed counterclockwise (we look at the bolt from the side of the cap). Unscrew the bolt with left-hand thread clockwise.

When deciding which way to unscrew the bolt, just look at it carefully:

• on the side you can see the inclination of the threads of the bolt at a small angle - unscrew the bolt in the direction in which the thread "rises";
• even if the threaded one is not visible, you can determine the direction along the end of the nut (or through the threaded channel in which the bolt sits) at the exit point of the last turn of its internal thread.

In the absence of visible signs, when only a hat tightly pressed to the surface of the part is visible, it is better to start unscrewing counterclockwise, if there is no result, then try against it.

How to unscrew a broken bolt

A bolt with torn edges can be unscrewed in several main ways:
·

• use the Super Lock head, which acts on planes, not on edges;
• clamp the broken bolt in a pipe wrench (in a vice, clamp, pliers, etc.) and unscrew it;
• make a cut in the head and unscrew with a powerful screwdriver;
• combine the two previous methods, using both a clamping tool and a screwdriver, which will allow you to apply the force of two hands;
• turn a smaller hat on a turnkey basis;
• use a special tool - an extractor (similar to a tap, the working part is conical, the direction of the thread is opposite to the thread of the stud): drill a hole of the desired diameter and a depth of about 2/3 of the length of the working part of the extractor in the center, insert the extractor and rotate with force until the bolt is unscrewed;
• drill a hole in the center of the cap no deeper than the height of the cap, drive a TORX nozzle (E-profile, or another similar one with longitudinal ribs) into it and unscrew the nozzle shank;
• hammer a large nut of a suitable size on top of the bolt head with licked edges, the inner diameter of which allows you to put it in tightness, for additional fixation, drill a recess in the contact zone of the nuts, insert a suitable metal rod there as a key to prevent rotation, unscrew the bolt using tool for the size of the nut of a larger diameter;
• put on a nut of a larger diameter and weld it to the bolt head with a semi-automatic welding machine, unscrew the large nut together with the bolt welded to it.

As you can see, unscrewing a bolt with torn edges is not so difficult.

How to unscrew a broken bolt

Information on how to unscrew a broken bolt that does not have a hat can be obtained from the article "How to Unscrew a Stud: 25 Effective Ways and Techniques", which is posted in the "Useful" section of the site.

How to loosen a rusted bolt

Unscrewing a rusty bolt is easier if you have access to the threaded part. As a rule, there is such an opportunity from the side of the end on which the nut is screwed (the bolt passes through the fastened parts), less often - from the side of the cap, when it does not fit snugly against the fastened surface. You need to act as follows:
·

• accessible threads must be thoroughly cleaned of rust with a wire brush, remove contamination;
• apply the penetrating compound WD-40, “Liquid Key” and their analogues to the thread (so that the applied compound flows from top to bottom into the area of ​​the rusty bolt thread sticking), let the compound work for 20 minutes, unless otherwise specified by the manufacturer of the product;
• using the available tool, apply force in the direction of unscrewing;
• if the bolt does not give in, then apply the pacing method, alternately applying force to both twisting and twisting;
• if these actions did not lead to a positive result, then apply soaking in a penetrating or chemically active preparation against rust for a long time.

How to unscrew a bolt with soaking

The essence of the method is the exposure of the rusty threaded part of the bolt to a penetrating or chemically active composition in relation to rust for a sufficient time for a long time.

Main methods:

• moisten the rusty fasteners in the thread area with an active agent, wrap the accessible threaded shank of the bolt with a rag soaked in this agent or put it on top (so that the chemistry flows down the thread from top to bottom), close it tightly to prevent drying, if necessary, adding fresh agent every few hours;
• dip the fasteners into the chemistry completely, using its large volume in a suitable container.

As a means for soaking rusty fasteners, you can use:

• special penetrating compounds WD-40, "Liquid key" and analogues;
• kerosene, gasoline, carburetor cleaner, lock defroster, brake fluid and others, from a garage stock;
• rust converter;
• compositions chemically active in relation to rust - table vinegar, iodine, Coca-Cola, etc.

How to loosen a stuck bolt

Before unscrewing the stuck bolt, it is necessary to perform preparatory steps that can make things easier:

• hit the head with a hammer along the axis of the bolt;
• apply rocking tapping with a hammer on the side working planes around the circumference of the bolt head;
• if possible, heat the fastened part in the area of ​​the threaded channel and try to unscrew it hot (if it didn’t help the first time, then repeat the heating several times).

In the latter case, you can use matches, a wax candle, a lighter, a burner from a gas cartridge, a blowtorch or a gas cutter for heating (the latter is extremely careful, at a sufficient distance so as not to damage the part).

To unscrew a bolt that does not want to unscrew, stuck, you can use a penetrating lubricant in combination with other methods of increasing the force.

How to unscrew a bolt without a screwdriver

If the bolt head is for a screwdriver, but it is not at hand, then the following options are possible:

• clamp the bolt head in a vice, pliers, clamping pliers or other similar tool with a bit from the existing set;
• if there is no cross or other curly bit, then use the method with cutting the cap under a flat screwdriver or turning the head on a turnkey basis (turn the opposite sides of the cap with a file, burr or grinder until parallel planes of sufficient area are formed);
• in the absence of a flat screwdriver or bit, use any suitable or specially sized object made of hardened steel - clamped in the tool listed above, it will act as a screwdriver sting;
• with a massive bolt head, methods can be used with fastening by welding or on the key of a large nut, or in another suitable way from those described above.

How and how to unscrew the bolt for an asterisk or hexagon without a key

Often, a bolt for an asterisk or a hexagon has a round head. How and how to unscrew the bolt without a key? Any of the suitable methods mentioned above can be considered for loosening stripped bolts.

How to unscrew a hard-to-reach bolt

Before unscrewing a hard-to-reach bolt, you need to prepare a special tool:

• wrench or ratchet with a short handle;
• ratchet with a large number of teeth in the mechanism (gives a small angle of rotation, which is important in cramped conditions);
• extensions to the heads;
• gimbals;
• flexible drives for heads.

If you plan to work regularly with hard-to-reach fasteners, then it is better to buy the listed tool, as part of a set or individually for actual tasks. For a single use, you can ask for the necessary time.

Conclusion

Before unscrewing the bolt, it is necessary to clean the threaded part of rust and contaminants, apply a penetrating or chemically active composition against rust, choose from the available tool what works best and only then apply effort.

Using excessive force and using the wrong tool will most likely result in damage to the head of the bolt, breakage of the bolt or tool.

When considering how to unscrew a bolt, immediately choose the most effective and reliable solution available.

When carrying out repair work, the question sometimes arises: how to unscrew a bolt or screw with torn edges. This problem has several solutions, knowing which you can unwind almost any hardware. Even in the case when you overdid it and tore off the head or broke the stud, there are ways and tools to unscrew the fragments of the fastener.

Any problem is better to prevent than to solve. Therefore, if you have applied enough force and the fastener does not budge, you do not need to continue until you damage it completely. Better do the following:

The above steps will not be superfluous in the case when you decide how to unscrew a bolt with torn edges.

Bolt removal methods

Below are the most effective ways to remove damaged bolts and screws.

With broken edges

When deciding how to unscrew a bolt with torn edges, you need to consider whether there is access to it, location, and also what tool you can use. Based on these factors, you can use one of the following methods:

In complex cases, in order to achieve the desired result, you need to combine several methods. Therefore, first assess the situation, decide how you can unscrew the bolt, and only then get to work.

With a broken head

Very often, when disassembling old threaded connections, you can not only damage the edges of the bolt, but also rip off the head. Then the question arises: how to unscrew the broken bolt. If you have separated the parts and the broken bolt protrudes from the body of the part, then you can use all of the above methods.

But how to unscrew a bolt with a stripped head if the bolt body does not protrude from the part? There are several options for solving this problem.

Precisely drilling a hole is quite difficult. And if you damaged the threaded connection, then you can correct the situation only by reaming the hole and threading a larger diameter.

A sheared stud is no different from a bolt with a stripped head, and therefore the methods for unscrewing it are the same.

Thread damage

There are times when the fastener thread is damaged. In this case, the hardware scrolls freely, but it cannot be removed from the threaded connection. To solve this problem, you need to lift the bolt. This can be done with a screwdriver or other similar tool that is pushed under the head and lifts it with effort. When the bolt rests, it begins to rotate in the direction of unscrewing. This is done until the hardware is completely removed. If the threaded connection hole is through, then it can be pushed from the back using any tool suitable for this.

If you have a similar problem with the nut, then proceed in the same way. Hardware with damaged threads must be replaced, therefore, if there is access, the nut can be cut off with a grinder or knocked down with a chisel.

Under an asterisk and a hexagon

Recently, fasteners with asterisk heads, hexagons and more exotic forms are increasingly used. If the edges on such fasteners are damaged, and you need to unscrew it, then you can act by analogy with ordinary bolts, with the only difference being that you need to use a tool with the appropriate shape of the edges to unscrew it.

Removing the screw

A lot of trouble is delivered by screws with torn edges. Unscrewing such screws is not easy, but there are several ways to solve this problem. In order to make it easier to unscrew them, you need to do the same preparatory measures as for the bolts.

In the simplest case, when the screw protrudes above the surface, you can try to grab it with pliers, wire cutters, or another similar tool and unscrew it in this way. But most of the time there's nothing to grab on to. Then you can try the following methods:

1. Sometimes it helps to use thin rubber, for example, from a balloon. A piece of such rubber is placed on top of the screw and unscrewed by pressing a screwdriver through it. This allows you to increase friction and avoid slipping of the screwdriver.
2. A screw with a figured head can be converted into a flat screwdriver by sawing a groove with a hacksaw.
3. In order to solve the problem of screwdriver slippage, you can use cyanoacrylic adhesive, this adhesive dries quickly and fastens metal surfaces with high quality. The procedure is simple: the screw and screwdriver are degreased, glue is applied to the screw head and the screwdriver is pressed against it, observing alignment. To speed up the setting of the glue, you can sprinkle it with soda. Wait for the glue to harden completely and try to unscrew the screw.

In order to avoid such problems in the future, renew all threaded connections with lerks or taps before assembly. Replace all damaged fasteners. Be sure to lubricate the threads and fasteners as a whole. It is best to use graphite grease for these purposes.

Many men, when repairing a car, or just at home, have come across “sticky” bolts and nuts. It sometimes takes hours to deal with rusty fasteners, while the master often runs the risk of breaking everything, and also filling a bunch of bruises. How to avoid this and learn how to easily and simply unscrew old bolts, see our review.

1. Patience

The first and most important thing to have in such a situation is endurance and patience. If the stuck bolt does not give in, you should not make super efforts to immediately move it. So you can cut off the head and tighten the repair, as they say, with your own hands. There are many effective tools that will help unscrew the problematic fasteners. More about them in the following paragraphs of our review.

2. Remove rust

To make the bolt or nut easier to unscrew, you need to remove all dirt, rust and paint. A stiff metal brush works best for this. Particular care must be taken to remove rust from the threads.

3. Tool selection

To unscrew a stuck bolt or nut, you need a box wrench or head, preferably with 6 edges. A regular open-ended wrench is likely to slip off the edges and cause injury. It is undesirable to use a 12- and 18-sided tool, as there is a high probability of slippage.

If the fasteners are already licked, it is worth getting a special head, which is called “for torn edges” or an extractor.

4. Direction of rotation

Most people are accustomed to the fact that all screws are twisted clockwise, and unscrewed - against. But in cars, fasteners with a reverse thread direction are often used, for example, left-hand wheel studs. Those who do not know this, for sure, will be "played" for a long time.

5. Lubricate rusty threads

Nuts and bolts that don't want to break easily can be treated with one of the many lubricants. Penetrating oil like WD-40 is very popular among motorists. By the way, this is a very useful drug in solving.

Penetrating oil is generously applied to the mating surfaces of the parts, and left for a while. If the bolt or nut is very rusty, you can leave the "chemistry" to work all night.

You can also moisten rusted parts with kerosene, thinner, plain water, or Coca-Cola. These remedies also help a little.

6. We are looking for a longer lever

The larger the handle of the tool with which the stuck bolt is torn off, the more likely it is that it will succumb. True, if the details are held tightly, then proceed to the next step.

7. Warm up the part

If it is not possible to unscrew the fasteners even with a head with a long lever, then the connection should be warmed up. Professionals use an acetylene cutter for this. But if it is not at hand, a mini-gas burner, which can be bought on the market, is also suitable.

Turning the pin out of the aluminum cylinder block, we heat the block itself around the thread. At the same time, periodically tap the pin in a circle. And if you need to unscrew the nut, then we heat it on one side, and also tap it with a hammer from all sides.

8. Remedies of last resort

Even if heating did not help, then rusted fasteners with a high degree of probability can no longer be saved. Pneumatic or electric impact tools are very effective, but nutrunners often break the heads of "difficult" bolts.

Unscrewing problematic nuts also often ends with their mechanical removal. To do this, the nut is cut into pieces with a saw or grinder, you can also drill with a drill in several places. Sometimes two cuts on opposite edges are enough, and the nut starts to rotate. And the easiest way to quickly split an old nut is to use a special device known as a nut cutter or nut splitter.

When removing a stuck nut using the methods listed above, the thread is sometimes damaged. To “align” it, it is enough to drive the damaged studs with a die.

And all men need to know
