Photo 1... Removing an old countersunk screw from a sash with glass.

Of course the simplest and quick way getting rid of old screws is a crowbar, but this method is only good when old ones are being disassembled wooden windows or doors before being taken to a landfill or when appearance is not critical. And in order to unscrew an old screw with a minimum of damage for the tree into which it is screwed, and for glass, if the work is carried out with sash(as shown in the photo), the following actions often need to be taken:

1. Clean the splines from paint

The slot (from the German schlitz - cut) is a recess on the head (head) of the screw for a regular or Phillips screwdriver. In Soviet times, with all sorts of handles, locks and other latches on windows and doors, they did not stand on ceremony, and therefore they covered it with oil paint, without hesitation and not paying attention to what was on the fittings or screws protective covering or not. Well, the paint, obeying the laws of physics, accumulated in the slots and dried there, replacing the putty. It is almost impossible to unscrew a screw with 3-5 layers of paint on a countersunk head without cleaning the slot. However, it is not so difficult to clean the old oil paint from the slot. It's enough to have any sharp enough metal object made of durable metal. A sufficiently strong metal means not only tool steel, but also different kinds pobeditovye and corundum solders on all sorts of scribes, in extreme cases, you can use a thin nail, in any case, its strength is much greater than strength oil paint... Personally, I use a special wedge bit for these purposes, previously this was included in a set of screwdrivers. With such a nozzle, you can not only bend wood, but also clean the slots from paint. However, the disadvantage of such a nozzle is that it is not always at hand. This happened in the described case, when in the country it was necessary to unscrew a couple of old handles, so a nail was used to clean the slots.

You need to clean the splines very carefully, the more paint you remove from the splines, the more likely it is that the screw can be unscrewed. However, this is not yet a guarantee of success. I don’t know exactly why, whether because there was some mistake or flaw in the screw-making technology, or screws for domestic purposes were made only on equipment worn out in the arms race, or from low quality steel, or simply because I only come across such old screws, but the slots of the old shovel screws are not of high quality. And their main drawback is that the slots are not deep. And the shallower the depth of the slot, the easier it is to “rip off” or “lick off” these same slots when unscrewing. After all, when we try to unscrew the screw, we must overcome the frictional force between the screw shaft and the wood. This force arises during elastic deformations of wood and does not weaken for many years and even decades, and if the screw also rusts, then it is still necessary to additionally destroy the resulting scale. And this is not always easy to do. Even a simple nail driven into wood, which can be immediately pulled out with a crowbar without any problems, after many years, due to corrosion, can adhere to the wood so that it is almost impossible to pull it out, just cut it off or break it off.

Sometimes if you have an old unnecessary screwdriver, you can sharpen it and use it as a chisel to deepen the slots.

2. Press the screwdriver as hard as possible at the very beginning of unscrewing

As already stated, the main task, overcome the frictional force and the adhesive force of rust, i.e. rip the screw off the ground. If you managed to turn the screw at least a quarter of a turn, then consider that the job is done, then everything will only get easier. With each revolution, the contact area of the screw with the wood will decrease and, therefore, the friction force will decrease. Sometimes in the process of unscrewing the slots are completely licked off, but if the screw is unscrewed at least half a centimeter, then you can continue to work with pliers.

3. Drill out the screw head

If the screw was hammered, and not twisted into the wood and at the same time bent, or rather, its axis changed its shape and became not straight, then to unscrew such a screw you need sufficient play, which can only be obtained if the screw to be unscrewed is the last one. And also if you tore off the slots on the screw head, but could not turn it even a quarter of a turn, then in these cases the best option- drilling the screw head. To do this, you need to have a drill and drill for metal with a diameter slightly larger than the diameter countersunk head screw. When you ripped off the splines, you can drill out the head without preliminary punching, and if the screw does not stupidly unscrew, but the splines are in place, then it is better to screw it first. However, in the course of drilling, the drill itself will fall into the pot. After the head is drilled out, you can remove the fittings and the rest of the screw, either unscrew it with pliers or hammer in deeper with a hammer.

There are probably other ways to remove old rusty screws, but I don't know them yet.

If the screwdriver constantly slips in the head of the screw, you need to create additional friction between it and the head, or apply more torque. There are many simple ways remove the screw with the help of household materials at hand. Of course, you will need special tools for tightly locked screws, but they are not so expensive and are always on sale.

Steps

Using a regular screwdriver

Maximize the grip of the screwdriver with the screw. If the head of the screw is not yet completely ripped off and the screwdriver is still clinging to it, try to unscrew the screw by hand one last time. To increase your chances of success, follow the instructions below.

Use auxiliary materials to increase the frictional force. If the screwdriver slips stubbornly in the damaged screw head, cover the screw with a small piece of material that will give the screwdriver and the head a better grip. Place a screwdriver against the head through this material and try again to unscrew the screw. The following can be used as auxiliary materials:

a wide cut elastic band (to make a strip of rubber);
a piece of steel wool;
a piece of green abrasive kitchen sponge;
scotch tape (with the adhesive side to the screw head).

Hit the screwdriver lightly so that it fits correctly into the slots. Hit the screwdriver carefully to avoid accidentally breaking the screw head. If you are working with a fragile object, skip this step.

Press down firmly on the screwdriver while rotating. Grasp the handle of the screwdriver with your palm and place your forearm in line with the screwdriver. Press down firmly on the screwdriver with your hand as it rotates.
- If the screwdriver slips into the head again, stop immediately. Further scrolling the screwdriver in the head will only deform it even more and complicate the process of removing the screw. Be sure to check that you are turning in the correct direction when removing the screw. Usually (but not always), in order to unscrew the screw, it should be turned counterclockwise (unscrew it to the left, and tighten it to the right). Strong pressure on the screwdriver itself prevents it from slipping in the head.
Heat the problematic screw. If you can heat the problematic screw without harming the object it is screwed into, this will help loosen the grip of the threads. Heat the screw construction hairdryer or gas burner constantly moving the appliance to avoid overheating. As soon as the screw gets so hot that a drop of water that gets on it will immediately begin to hiss, leave it to cool, and then try to unscrew it again.
- This is especially helpful when the screw is screwed in with a bonding agent or adhesive.
Use a hacksaw to cut a slot in the screw head for a flathead screwdriver. If you still cannot move the screw from its place, cut a groove in its head. Then insert a flathead screwdriver into the slot and try to remove the screw. This step can be combined with any of the above steps.

With an impact screwdriver
1. Take an impact screwdriver. An impact screwdriver is hand tool, the tip of which cuts deeper into the screw head due to the action of force and spring. This screwdriver is well suited for sturdy building structures but it can damage electronics and delicate equipment. If you are concerned about damaging an object with a stuck screw, avoid cheap heavy-spring screwdrivers as they require more hammer blows.
  - It is also not recommended to use an electric impact screwdriver, as excessive force can damage the surface into which the screw is screwed.
2. Adjust the screwdriver to loosen the screws. Some screwdriver models have a switch. In other models, the direction of rotation is set by turning the screwdriver handle.
  
  Place a screwdriver against the head of the screw. Insert the correct size bit into the screwdriver. Attach the screwdriver to the screw and hold it strictly at a 90º angle to the plane of the head. Grasp the middle of the screwdriver handle so that the end of the handle is free.
  
  Hit the screwdriver with a mallet. Hit the screwdriver handle firmly with a heavy mallet. Rubber mallet avoids scratching the screwdriver handle.
  
  Check the direction of rotation of the screwdriver. Some impact screwdrivers reset the spin settings after each hit. If the setting is reset, move it back to the unscrewed position.
  
  Repeat the procedure until the screw gives way. As soon as the screw starts to loosen, go to a regular screwdriver and unscrew it from the hole.
Using an extractor
1. Place a hole in the center of the screw head. Place the center punch exactly in the center of the screw head. Hit the center punch with a hammer to make a notch for the drill setting.
  - Use eye protection against flying metal filings. Do not remove protection until the very end of work.
2. Drill a hole in the screw head. Get a quality drill designed for drilling in hard metals. The extractor must be marked with a suitable drill size. Drill slowly and evenly (if possible, use drilling machine). First, drill a hole 3-6 mm deep. Because of too deep hole the screw may break. It's a good idea to start drilling the screw with a thinner bit to make it easier to work with the thicker one later.
  
  Hit the extractor in the hole with a brass hammer. The hardened metal of the extractor is brittle enough that an iron or steel hammer can break it. Tap the extractor until it snaps securely into the drilled hole.
  
  Rotate the extractor carefully. If the torque is too harsh or uneven, the extractor may break, aggravating the situation. The safest way to unscrew the screw with the extractor is to use the handle supplied with it. The drilling itself should have loosened the screw, so it should be unscrewed without much effort.
  - Some extractor kits have a hexagonal non-working end. Grasp this end with two wrenches, positioning them 180º apart to distribute the force evenly.
3. Heat the screw if it doesn’t give way. If the screw does not come out or you are afraid of breaking the extractor, remove the tool. Heat the screw with a torch and then drip it with paraffin or plain water to lubricate the threads. When the screw has cooled down, try using the extractor again.
Additional methods
1. Hire a professional. If all your efforts have gone to waste, hire a craftsman who can remove the screw using an EDM machine. This is often the only way out in the event that the extractor breaks off in the screw head.
- If you have the opportunity to inspect reverse side the surface into which the screw is screwed, check if it is sticking out there. If this is the case, you can use a pair of pliers or a box wrench to grab the end of the screw and twist it from the inside to the outside.
- Make sure to rotate the screw in the correct direction. The screw may have a reverse thread, which requires clockwise rotation to remove it.
- If the hole left after the screw is damaged, then the situation can be corrected in several ways.

A very common problem when conducting construction works is the deformation of fasteners associated with the inexperience of the performer. However, sometimes it can be difficult even for professionals to figure out how to unscrew a screw with torn edges, and also to prevent a similar situation from repeating in the future. Let's think about solving this problem together.

Causes of deformation of faces

It is no secret that unscrewing a tightly seated screw or self-tapping screw with the edges torn off from the body of the material can take a lot of effort, time and nerves, which is why it is advisable to take care of preventing such situations in advance.

And the first thing you should pay attention to is the quality of the tooling, because it is the wear of the tool that, in most cases, becomes the reason for the "licking" of the edges of the fasteners. A similar circumstance is connected with the fact that the tip of a screwdriver or bit for a screwdriver is not sharp enough and does not provide full contact of the screw with the working tool. Also, a similar phenomenon can be caused by a discrepancy in the equipment used, therefore, before carrying out work, it is advisable to make sure that the tool tip is completely immersed in the slot of the fastener, thereby ensuring a sound connection.

The second reason for the deformation of the edges of the screw / self-tapping screw is non-compliance with the screwing technology, which in most cases manifests itself in the case when the performer applies insufficient force to the tool, that is, does not press on it properly. Or the equipment (screwdriver, screwdriver) is located at an angle to the fastener. In addition, screwing in the screws at high speeds can also damage the head of the fastener.

The quality of the screws themselves (type of material, correctness of shape) also affects the correctness of their installation, therefore, before purchasing the fasteners directly, you should inquire about their technical characteristics.

Technique for unscrewing a screw with torn edges

If a trouble with the screw still happened (a screwdriver or a bit began to turn, jumping over the edge), you do not need to despair and try your best to turn the "stubborn" or even worse hammer him in, but simply stop and take all possible actions to remove the fasteners from the body of the material. Moreover, depending on the circumstances, you can use one of the following methods to solve this problem.

Removing the screw

The first step is to try to remove the deformed screw. standard method by unscrewing it. However, this operation should be done only quality tool, which may require the purchase of additional equipment (bits, screwdrivers).

If the above action did not give the desired result, and the edges of the screw "licked" even more, then you will have to apply more radical methods.

So, if the screw is not screwed into the body of the material for its entire length and the head protrudes slightly above the plane of the material, then it can be unscrewed using pliers, round-nose pliers or a gas wrench. For this, it is enough to squeeze the screw head with sponges of a locksmith tool and unscrew the fasteners counterclockwise.

When the screw is completely screwed into the body of the material, then it is unlikely that it will be possible to unscrew the fasteners without damaging the above method. Alternatively, it is advisable to use the following techniques.

Sawing edges

Allows you to provide a screw with a recess of 2-3 mm, with which (using a flat screwdriver with a sharp tip) you can unscrew the product. And it is quite simple to make such a slot using an ordinary metal sheet.

Threading

On a professional level, a jammed screw can be unscrewed using a special tool (left-hand thread tap). For this, a hole should be drilled in the body of the fastener with a diameter smaller than the diameter of the screw, and after that, an extractor should be screwed into the resulting hole (counterclockwise) and when it stops, unscrew the fastener.

If all the above methods did not lead to the desired result, then the screw with the torn off edges is simply drilled with a drill with a drill for metal.

Before unscrewing a screw with torn off edges, it is advisable to familiarize yourself with a number of recommendations, due to which the work of removing fasteners will be less time-consuming.

To form a free gap between the self-tapping screw and the body of the material into which it is screwed, the fasteners can be heated (for example, using a soldering iron, an industrial hair dryer or a lighter). At the same time, in the process of heating and subsequent cooling, the screw will slightly increase, and then decrease in size, thus expanding the material into which it is screwed.

In the last article, we looked at all sorts of problems associated with nails. In addition to nails, screws, self-tapping screws, etc. are indispensable fasteners. Often, a lot of troubles arise with them. In this article, we will tell you the most common difficult screw situations that can be solved by a fairly simple method.

1. Often, screws are used to connect wooden products... In the case when the tree has high density- it is difficult to twist and even start to twist. To do this, you can recommend making a small hole in the place where you will tighten the screw - you can use a sharp awl or a nail. In order for the screw to enter the tree more easily, it is necessary to pour soap shavings near it.

If you need screw in a screw v chipboard end or boards, so that it does not tear the material, drill a small hole, about 50% -60% of the screw diameter. Further, we recommend filling the hole made with Moment glue (other glue is not recommended). After a day, you can screw a screw into the hole. Thanks to the performed procedure, the material during the screwing process will not collapse and delaminate.

2. If you need to shorten the bolt with a hacksaw, you can initially recommend that you screw the bolt to the required distance, along which you can cut off.

3. If the place where the screw should be tightened is difficult to reach, then here you can recommend using a fishing line. Having tied the head of the screw - press the end of the flattery to the screwdriver. Thanks to this simple method, the screw will not fall, and you can screw it where you need it without spending time and nerves, and after you tighten the screw, the line will fray itself. Also, instead of fishing line, you can take a thread.

4. In order to tighten the self-tapping screw in difficult places, you can offer another such improvement. Drill a hole in the screwdriver handle and place the magnet there.

5. Often needs to be repaired old furniture or other interior items. In this case, for sure, the bolt or self-tapping screw has long been rusted, and it will be very difficult to unscrew them. It is not uncommon that there is not enough strength to simply turn the screw. Let's use the leverage rule. Drill through a transverse hole in the handle and insert a rod made of strong material into it. In such a simple way, the effort that can be applied to unscrewing the bolt significantly increases, while you do not have to spend a lot of effort, and it will be very convenient to unscrew complex bolts or screws with a knob.

6. If you have to work on tightening the mass of self-tapping screws, and you do not have a screwdriver, despair. A drill that has a rotary knob on the button may also work for you. Thanks to this, you can carefully and with the necessary effort tighten the screws in the right place and in required material... However, in addition to this, you will also need to purchase the so-called "cue ball" - this is a rod - on one side of which there is a cross, for tightening the bolts with a cross for a screwdriver, and on the other, for a flat screwdriver. I recommend that you buy a high-quality "cue ball" so that it does not twist after a few tightened bolts.

7. When unscrewing complex and old screws and bolts, it is possible to recommend using additional means of assistance, such as kerosene or special tool"WD-40". Having sprayed into the junction, the liquid penetrates the junction and softens the problem areas. Thanks to this, the unscrewing process is greatly simplified.

In general, the household should have screwdrivers of various diameters and purpose - up to special L-shaped screwdrivers and a flexible extension, which allows you to unscrew the bolts in those places where you cannot crawl with a regular screwdriver.

When carrying out repairs or construction work with your own hands, it often happens that you need to remove the screw from which the head is torn off. Depending on the type, size and material from which the screw is made, can be used different ways retrieving it. It also matters how badly the slot is torn off and the material into which the screw is screwed.

You can remove the rest of the screw using special tools - extractors. They are selected according to the size of the screw, screwed into drilled hole counterclock-wise. After the extractor is jammed, you can remove the screw. In the absence of such a tool, you can unscrew small screw with a torn off head with improvised means.

Removing a screw

There are several ways to remove the screw if the head is completely torn off:

If the diameter of the bolt allows, you can drill it with a drill with a drill of a suitable size.
If you use a smaller drill, you can place a bent nail in the drilled hole and unscrew the screw.
If you need to unscrew a small screw, you can drip super glue onto it and attach a screwdriver. After the glue hardens, you can try to unscrew it. Liquid nails can be used in a similar way.
If the size and material into which the screw is screwed allows, you can use welding, then you need to weld the nut from above, and then unscrew it.
On a large screw, you can cut a slot with a hacksaw and unscrew it with a screwdriver.

If the head is not torn off completely, you need to very carefully heat the screw so as not to damage the material into which it is screwed, then try to remove it.

Broken edges

If the edges of the screw are torn off, and the screwdriver turns when trying to remove it, you should:

Saw out the edges so that the flathead screwdriver can snag.
Rest the chisel against the edge of the head and, tapping with a hammer, try to turn the screw.
Use a flare head or an adjustable wrench to remove the stripped screw.
Remove the screw by positioning an impact screwdriver on the edge of the head.
Place a flat screwdriver under the head and lightly hit the handle with a hammer.

In the event that none of the options fit, you can break the screw into pieces with a chisel and chisel and remove it from the hole.
