How to unscrew a screw whose edges have broken off? Anyone who does even a little farming is familiar with this situation.
You need to unscrew the screw. You take a screwdriver, start unscrewing it, and become convinced that your efforts bring no results. The screwdriver turns, but the screw remains in place.
Most often, this happens with Phillips screws.
What to do, how to unscrew it?
You can, of course, pry it out with a screwdriver and try to grab the screw with pliers. This gives results, but there is a high risk of scratching the surface, and you will have to tinker a lot.
We offer a simple method that anyone, even a woman, can do. Moreover, this method is perfect when you don’t have a screwdriver that fits the size.
The essence of the method is elementary. You need to put any rubber band on the head of the screw. Whether for money or for hair. Any size elastic band will do.
You need to put the rubber band on and calmly unscrew the screw. That's all.
For clarity, watch the video, after which everything will be clear to you.
How to unscrew a broken screw. Video
So simple and useful way. Keep this information for yourself, and you will never be afraid to unscrew any screws, even the oldest ones.
The edges of a screw usually break off at the most inopportune moment, regardless of whether you are a master or a beginner. Due to the fact that the screwdriver tip does not fit tightly enough into the grooves on the screw head, the screwdriver tip slips during rotation, as a result of which the edges on the screw are torn off. When heated, the screw, although slightly, will expand and increase in volume, compressing the material into which it is screwed. Thanks to the lubricating properties of the liquid, the friction force between the screw and the material will be significantly reduced and the screw will become easier to unscrew. There are no hopeless situations, and solving the problem of unscrewing a screw with broken edges is proof of this.
Video - The best ways to remove a broken screw
Need to pick up right size for screwing into the torn slot. Install the extractor into the screwdriver chuck and tighten the chuck securely. Since the extractor has a reverse thread, this means that a drill with the extractor installed in reverse will drill into the head.
Why do the edges on the fasteners break off?
The screw also breaks when too little pressure is applied to the screwdriver. On the other hand, a screw may be fairly new, but it bends and subsequently breaks due to poor quality. As soon as your screwdriver slips along the edges for the first time, don’t get excited and repeat the procedure. Perhaps in your case the screwdriver simply does not fit the screw you have chosen. Therefore, you can try your luck by using several attempts with other screwdrivers. The screw will move from its place and then it will probably be possible to remove it. This method is also applicable if the screw is prevented from being unscrewed by a broken thread.
To do this, it is enough to have any sharp enough metal object, made from durable metal. With this attachment you can not only mark wood, but also clear paint from the slots. And their main drawback is that the slots are not deep.
Maximize the quality of the screwdriver's grip on the screw. Be sure to check that when removing the screw you are turning it in the correct direction. Firm pressure on the screwdriver itself prevents it from slipping in the head. Heat the screw construction hairdryer or gas burner, constantly moving the device to avoid overheating.
Step 1: Rubber Band (Elastic Band)
Ideally, tools designed for repairing glasses should be used for unscrewing (there will be no difficulties in finding them, and they are not very expensive). It is advisable to insert the tip at a slight angle to increase the contact area. Use a nail file.
This screwdriver is well suited for durable building structures, but it can damage electronics and fragile equipment. A rubber mallet will prevent scratches on the screwdriver handle. Check the direction of rotation of the screwdriver. Repeat the procedure until the screw gives way.
Step 1. As noted earlier, there is only one recess on the head of such a screw. Use only an unnecessary card, because it may well be damaged during unscrewing. Step 7. The last method is to use pliers.
Types of screws
The slot of this screw is broken. In such fastenings, the entire load falls on the screws. Both the hole and the slot are damaged. Then, when removing the slot, the fastening materials are damaged. Even if adhesives are not used, corrosion can also do the dirty work: rusting, metal fastener becomes one with the tree. Do you know anything about a special attachment designed for unscrewing damaged screws? Hit the punch with a hammer, but not too hard, because the diameter of the rod is already small, do not damage it even more. The size of the extractor must match the size of the screw.
The problem can be resolved by heating the fastener. When it cools, space will be freed up in the structure of the workpiece, which will allow the adhesion to loosen. Once the fastener becomes hot to the touch, stop heating.
If a stripped screw sits deep in the material, and there is no other way to remove it... It’s time for a “cheap and cheerful” option.
If so, then you should only work with a longer recess to make the task easier. The method often works only with small screws. Step 5: Use the old CD. After waiting a bit for the melted plastic to harden, turn the brush counterclockwise.
Sawing edges
Fastening any products with screws, convenient and reliable way. Let's try to figure out how to make unscrewing more effective. More precisely, the slot in its head breaks off.
To do this, you should use a hacksaw for metal with the thinnest possible blade.
Often the corners (edges) formed by the intersection of the recesses wear down and become brittle, making it very difficult to remove such screws. Use your fingernail. Insert the edge of the old CD into the long recess and turn it counterclockwise. Use pliers. Torx-protected screws are also available; they have a rod in the center of a recess in the shape of a six-pointed star. Use a small flathead screwdriver.
It fits well into the cap and is secured to its inner surface with the help of numerous notched teeth. Place the punch exactly in the center of the screw head. Get a quality drill bit designed for drilling hard metals. Drill slowly and evenly (if possible, use drilling machine). Tap the extractor until it is securely seated in the drilled hole.
Of course this method is not applicable so often, since not every part can be heated in this way. Alternatively, instead of a blowtorch, you can use a soldering iron or an industrial hair dryer; this option is suitable for small screws. Place a chisel against the head of the bolt and try to rip it out of place. with strong blows hammer. There is an electrochemical option for unscrewing old screws and bolts.
It is important that the tip fits tightly into the groove and is not damaged.
Quite clear and intelligible for wooden structures. But what to do if the threads on the bike bolts are broken? Bgg, my handlebars came off, right on the stem mount.
The most effective and generally accepted method of dealing with bolts that won’t come off is to wet it (the bolt) with penetrating liquids (WD-40, kerosene). Such liquids penetrate deeply into the threads of the bolt and lubricate it, after which the bolt slides more easily along the threads. Effective method Unscrewing stuck bolts requires oblique blows to the head. Usually this is a drill with a reverse thread.
Step 6: Leave it alone?
A small misfortune, like a broken screw, happens... various reasons. It happens that in a solid material, a screw simply breaks off, and part of it remains in the body of the material. It is possible to remove a broken screw different ways. If there is no protruding part, then you need to deepen them in the area of the screw to the edge of the break and grab it. So far there is no particular pull from here. This is probably the most important thing.
The meaning is the same - “to remove rust from the place... And if the screw is stuck, then a common way to deal with this problem is to soak it in Coca-Cola. After the screw has oxidized, or better yet, left it overnight, for example, it must be warmed up thoroughly! We work with glasses. The resulting hole may not be very even, but after a little correction mortar, in this place you can hang a shelf again, for example. Very good and useful tool, it comes with attachments (bits) for all occasions, and it’s not very expensive.
An extractor can be a solution to the problem. On opposite side The device has a perpendicular crossbar with which you can perform rotations. Next, you need to use the extractor itself. Then you need to turn the device several times.
We try to press it in as hard as possible. Instead of a rubber band, you can take any rubber plate or other part. In order to no longer suffer from licked screws, you can fix them.
Maybe, of course, this is not entirely on topic, but my father, when in the old days he was fixing something at home, constantly asked me to bring him soap from the bathroom. Firstly, you first need to make one sharp, sharp blow to the screw head. I was in such a situation and, to be honest, I didn’t always manage it positively.
Moving under light pressure towards the handle, the nozzle will also inform you about the depth of the hole. Hand drill will help you out when you need to wrap a large number of screws.
Why is it so important to preserve material? By opening the question, it will be possible to obtain a more reliable answer, avoiding disputes between those giving answers. The main thing is to do everything confidently so as not to break the drill. What if the cap is deep and there is no way to get to it?
Very often we are faced with broken screws, the removal of which sometimes seems almost impossible. If there are no edges on the torn screw at all, try unscrewing it with a small adjustable wrench. If you have heated the part, start cooling the screw. If you heat up the screw, cool the part. As a result of the resulting temperature difference, the broken screw should be able to be unscrewed.
Inspect the condition of the screw. Be careful not to damage the new notch with excessive force. Before you begin to remove a stripped screw, you need to assess the need for its removal.
I always managed to get it out this way. Then it is no longer possible to get close to him. How to make a hole in a tile for a socket? Yes, it’s elementary, a professional will answer! In this video we will look at one method, the other two I will simply describe the manufacturing technology to you. Maybe you decide to tell us about your renovation, write, we will be happy to listen.
You should take a tool with an unworn sharp tip and try to non-violently remove the unruly fastener.
Something simpler, the simplest, so as not to damage. And as for the burnt screws (as I understand it, they were exposed to high temperature) - they could harden or, on the contrary, fall. Probably everyone has at least once encountered such a nuance as a sagging ceiling. Holding the other end, mark the place where the nail will be hammered.

Instructions
To begin with, try to remove the self-tapping screw using a regular screwdriver - with the assistance of a needle file, make a groove for the straight slot of the screwdriver and try to unscrew the part. If it doesn’t work out, don’t try too hard, it will only make the situation worse. Try other methods.
If the case is not completely advanced, then you can try the following fairly simple method - select a drill bit with a diameter that matches the thickness of the self-tapping screw. And drill it until the cap separates from the leg. This must be done very carefully, since the metal shavings flying at this moment are very small and actively strive to get into your eyes. Be sure to use special protective glasses! Many craftsmen strongly advise using a pin driver, noting it high functionality and efficiency even in the most difficult cases.
Once the part holding the screw is removed, all that remains is to pull the leg out of the base. This can be done using pliers or simple pliers.
If the diameter of the screw allows it, you can use another quite effective, but also very labor-intensive option. To do this, drill a hole along the axis in the screw, large enough to insert a nail or any other thin and hard object into it. metal part. After this, carefully drive it halfway into the hole you made. Bend it and, again carefully, begin to unscrew the screw. In this case, be prepared to spend a significant amount of time – it’s a piece of jewelry work.
If the screws are rusty, use WD 40 - this is a product that allows you to remove excess moisture. Just fill the stubborn part with it and, if possible, try to move it to improve the penetration of the substance between the screw and the base. After about half an hour, try to remove the screw again. Please note that the surface that has been degreased with WD 40 must subsequently be lubricated. Otherwise, corrosion and, accordingly, destruction of the part cannot be avoided. Therefore, use this product only for cases similar to the problem described, as well as to remove moisture from mechanical surfaces parts and devices.
Unscrew the bolt, rusted or stuck to the base is not so easy to become. It happens that unscrewing one bolt or unscrewing one screw takes up to 90% of the total time to repair a product. Problem unscrewing bolts or nuts occurs most often on parts that are intensively used in aggressive environments.
For the metal from which both fasteners and structural elements held together by these fasteners are usually made, the aggressive environment is water and moist air.
Most fasteners have right-hand threads and unscrews COUNTERclockwise arrows.
Why is it difficult to unscrew a bolt or screw?
Before you start unscrew the bolt let's estimate the likelihood of successfully unscrewing it, or rather, the likelihood of problems arising with unscrewing:
The bolt or screw is rusty (rusty head, leaks from under the head, etc.);
The base (nut) into which the screw or bolt is screwed has undergone a change (swollen) wooden plank, metal base is flattened, etc.);
The fastened parts are displaced relative to their original position, which increases the load on the fastener.
If at unscrewing a bolt or screw we see manifestations of the above factors, after the first test we should move on to measures aimed at making it easier to unscrew our fasteners.
Methods for loosening complex bolts and screws
The most effective and generally accepted method of combating non-unscrewing bolts- this is wetting it (the bolt) with penetrating liquids (WD-40, kerosene). Such liquids penetrate deeply into the threads of the bolt and lubricate it, after which the bolt slides more easily along the threads.
Usually, when unscrewing a complex bolt, it is enough just to move it from its place, then the process of turning it away becomes easier. You can remove the bolt from its place by lightly hitting it with a wrench. You can move the screw by hitting it with an impact screwdriver.
Effective method unscrewing stuck bolts is oblique blows on the cap. Because It is not possible to hit the head of a bolt or screw with a hammer; use a chisel. The chisel is placed on the edge of the cap at an angle and short blows are applied to its base. Using a chisel, you should check the condition of the cap unscrewable bolt, if you cut it down, the process may take longer.
There are special tools for unscrewing complex bolts and screws. They are called extractors. Usually this is a drill with a reverse thread. By cutting into the head of a non-removing bolt or screw, the extractors, with their threads, create the necessary area of contact with the screw and force it to turn at the base.
If unscrew the bolt or screw If it doesn't work, you can cut it off (or drill it out). If you have to cut off the head of a screw, then it is almost impossible to get it out of the base, and in this case they usually mark a new place for fastening or drill out the screw completely, after which a plug is hammered into this place.
If the problem unscrew a bolt or screw is not due to the fasteners sticking at the point of contact, but due to the lack of a suitable tool, then you can make such a tool yourself, or use another tool.
So for unscrewing the screw with a Phillips head, you can use a flat screwdriver smaller size. A thin flathead screwdriver with a flared blade can be used to unscrew a bolt or screw with an asterisk or hexagonal slot.
A large hexagon slot can be unscrew the bolt head of the appropriate size, for this a nut is screwed onto it and secured with a lock nut.
The “oblique triangle” slot, intended only for twisting, can be unscrewed with a drill, unscrewing it in the opposite direction (counterclockwise) or, if space allows, cut off with a chisel or screwdriver.
For unscrewing deep screws(usually in household appliances) you can make a long screwdriver from a piece of steel wire. To do this, you need to flatten one end of the wire and sharpen it with a file to the shape of the slot, make a handle on the other side of the wire, bending the wire to the side.
Unscrewing a difficult bolt or nut, remember that by applying significant force, you can damage the structure itself - be careful!
Self-tapping screw is one of the the most popular types modern hardware products. Often repairs cannot be done without a set of self-tapping screws. The self-tapping screw differs from other hardware in that it has a special external thread, which, when screwed in, forms in the target hole of the connected object internal thread. Unlike its counterparts, the screw and screw, the self-tapping screw has a triangular thread that completely covers the surface of its rod. Our self-tapping screw calculation will help you choose and buy the right amount of hardware. After all, in a store, hardware is sold by weight, and the ratio of the weight of hardware to their quantity is easy to determine using this calculator. Possessing the right amount screws, as well as a tool for screwing them in, you can get to work. However, situations often occur in which the hardware is installed incorrectly. After all, there is always a possibility that the self-tapping screw will be screwed in crookedly, or in an inappropriate place for it. What to do in such situations? The answer is obvious: you should always buy hardware with some reserve. However, this is not enough. In addition, you must be able to properly dismantle “failed” screws. It turns out that this process is not as simple as the process of dismantling any hardware product. In the case of a self-tapping screw, its removal becomes even more difficult due to the fact that it deforms the surface into which it is screwed. It cuts threads in the material by itself, and when unscrewing, you need to act extremely carefully so as not to damage the surface even more.
Let's assume that the self-tapping screw was not screwed into the wall or other structure satisfactorily. It sits tightly in the surface, and it is not possible to unscrew it. What to do in this case?
In the case when a self-tapping screw does not lend itself to the unscrewing action of a screwdriver, and the screwdriver, in turn, begins to move and scroll without catching the edges in the head of the screw, there is no need to continue panicking attempts to unscrew the hardware! This may cause the edges in the cap to be torn off. And in this case, the process of removing hardware becomes significantly more complicated.
You need to take a screwdriver, install it in the recesses on the head, press with great force on the end of its handle and try to unscrew the screw with alternating movements to the left and to the right. If it was not possible to unscrew the hardware using this method, then you need to take a special screwdriver with a hexagon located at the end of the handle. The hexagon is needed to provide additional pressure on the screwdriver with a wrench. If this fails, you can try to unscrew the self-tapping screw using the extractor screw. This is a special attachment for screwdrivers, which is capable of completely covering the edges of the screw, which will significantly improve the adhesion of the tool to the hardware. In addition, you can try to loosen the adhesion of the screw to the surface by hitting the end of the screwdriver. You can also insert thin rubber inserts into the slots on the head, which will prevent the screwdriver from turning. And finally, radical way To get rid of the self-tapping screw, drill it out using an electric drill and a metal drill.
