At what speed to screw in screws with an electric screwdriver
Electric screwdrivers have additional features that can be a key factor in choosing a device. These are the functions:
Torque adjustment. The ability to change the torque of a screwdriver is very important for delicate applications
For example, when tightening screws on a motherboard, it is important not to over tighten, because it can cause cracking, which in principle can damage the motherboard. Usually the adjusting ring has 15 to 21 positions.
Virtually all screwdrivers allow you to adjust the bit speed by the amount of force you exert on the trigger. However, some models have two default speeds that you can switch between. For example, you can screw self-tapping screws in wood at maximum speed and unscrew/screw fasteners in appliances at minimum speed.
Impact mode. The impact mode in electric screwdrivers is designed to reinforce the screwing of fasteners into the workpiece. Relatively few models have this mode. Do I need to buy such a screwdriver? We don’t think so, since it weighs a lot and costs as much as a good electric screwdriver. The Makita TD022DSE is an example of such an impact screwdriver.
- Two batteries. Here is this “plus” we consider one of the most important, because the autonomy in electric screwdrivers is relatively small (depending on models), but it needs to work all day. Since it is more expensive to buy an extra battery than one that comes with the device, it is better to buy a screwdriver with two batteries at once.
- Motor brake. An optional device in the screwdriver that brakes the motor in a second, after you release the start button. Thanks to it you will not have to hold the device on weight extra time, waiting until the chuck stops. If you have to work several hours a day with a screwdriver, the feature helps a lot.
- Backlighting. Backlighting is usually organized in the form of a single LED. It allows you to work in low light conditions. Some devices additionally have a flashlight at the end of the housing.

Very often during repairs, masters are faced with such an unpleasant phenomenon as a loose screw hole. The main problem is that it is almost impossible to screw the metal into such a hole again. If you find yourself in such a situation, you have to go to all sorts of tricks that could help solve the problem. Here are some of the most simple, accessible, and yet popular ways.
The easiest, most affordable and obvious way to solve the problem with tightening a screw in a loose hole. At the same time, this method is also the least effective. All you have to do is put one, two or more matches in the hole before the screw is driven in. This method can help only in the most unstarted variants, when the deformation of the hole is not too large yet.
The method is generally similar to the method with the insertion of matches, but there are nuances. In most cases, it is recommended to screw the screw not next to the wooden element, but into it. And this in turn means that it is highly desirable to pick up such wedge for work, which will completely (or at least almost completely) overlap all the ragged hole for a screw.
A great way to solve the problem of a loose screw hole that works backwards. In this case, it is not the hole itself that is sealed, but the metal part that will be screwed into it. All you have to do is choose a suitable flexible wire and wrap it around the screw all the way from the cap to the end. Depending on the nature of the wood damage, the wire can be wound either more tightly or more loose. The method is recommended if the hole is not too badly damaged.
Also: glue and sawdust
The best, tried-and-true, and most effective method for repairing wobbly screw holes. Great for working on a wide variety of materials, whether it’s a sawdust composite or regular wood. The essence of the method is very simple: mix sawdust, wood chips and wood dust with PVA glue, so that the output we have a porridge with the consistency of thick sour cream. The mixture is thoroughly mixed, insists for a couple of minutes, after which it is tightly placed in the damaged hole. There thoroughly pressed and dried. When the glue dries, you can safely screw in the screw.

Repairing the fixing point
It often happens that a hinge is torn out of the door or a hole is drilled in the wrong place, and a new hole must be drilled very close to it. In the first version of the defect is not too difficult to repair, but in the second situation, the problem may seem difficult to many. a thin bridge of material between two holes located too close to each other can break. In both situations, there is no reason to get upset. how to fix the hole in the door of the chipboard will consider further. There are two ways to restore it:
- If the furniture is old and the material simply does not hold fasteners, it is easier to fill the damage with epoxy resin and immediately insert the fasteners in the right place. After it has dried completely, it will hold.
- If it is necessary to displace the fastening point or just re-screw the screw into the broken hole, you can do it in a different way. A wooden insert is used. Drilling the hole a little wider than it was, the wooden insert is inserted into it with glue. When the glue dries, you can screw the self-tapping screw back into place.
When deciding what you can patch a hole in the particle board under the new fastener, do not choose a mixture with sawdust. It will hold the self-tapping screw worse, and it will most likely fall out again along with the patch you made. Better to take a cork made of wood. it will be much more reliable. When shifting the hole by a small distance first patch the old and the lintel, too thin to hold the new screw, in this case an obstacle to the normal fixation of the fastener will not.
How to remove the screw or screw, even if it is stuck for good

Screws, screws or self-tapping screws not unscrewed from the material. a common problem, and in the course of repair work with it almost everyone has faced. Causes of this phenomenon are many. For example, it could be a defective fastener, a damaged slot because of inexperience or a worn-out tool that does not ensure good contact with the part to be unscrewed. Sometimes it seems that the jammed fasteners are impossible to remove, because they are so tightly stuck, but the problem is quite solvable.
If the screwdriver keeps slipping out of the slot, the reason can be a frayed stinger. In this case the tool is replaced by. Insert a new screwdriver into the head of the screw, making sure that the tip is firmly pressed against the slot, firmly seated in the groove, and try to unscrew the fastener.
Useful tip from Novate.When a fastener cannot be unscrewed, the first thing to do is to stop. Attempts to continue unscrewing can aggravate the situation, and a constantly popping screwdriver can damage the material. Assess the condition of the screw and try other ways of removing it.
Screwing Into Wood
In case a jammed screw or a self-tapping screw is not all the way in and the tip is sticking out over the surface of the fastened part, you can try to extract it with the pliers or the pliers. Gently, so as not to damage the material, use the clamps of the tool to grip the flat of the fastener at the sides. Then slowly unscrew the screwdriver by turning it anticlockwise.
A screw that is not fully embedded in the material can be tried to remove with an electric drill or electric screwdriver. Open the tool holder, place it over the screw head, tighten the locking mechanism and secure the flat bar in the chuck. Then you put it in reverse and carefully unscrew the screw out of the material. This works with almost any type of threaded item or jammed bolt, as long as there is a part of the head that the chuck can get a grip on.
If the fastener is sunk all the way in, you can try to improve the bond between the flat and the screwdriver with some material. It could be a piece of abrasive layer of ordinary kitchen sponge or duct tape glued to the defective flat bar. But it is better to use a strip of rubber or leather. It can be any width, though a piece that will cover the head of the screw completely is desirable. This provides a large contact area between the head and the tip of the screwdriver or the bit of an electric screwdriver. Put a piece of rubber on the head of the fastener, put a screwdriver on it and try to unscrew the stuck part.
Notching the face
If the screw head is torn off or has worn edges, you can make a notch in the flat of the screwdriver’s head to improve the contact area of the flathead. The notch should be made with a dremel, angle grinder or other metal-cutting tool. But this method will damage the surface of the material if the screw is deep.
Useful tip: If the material allows it, you can use the metal’s ability to expand when heated and contract when cooled. Stuck fasteners are heated with a lighter, blowtorch or construction hair dryer. The screw will expand slightly, spreading the material and then return to its previous position as it cools. This can create a microscopic gap between the rod and the material, loosening the fastener slightly and making it easier to unscrew.
If the previous methods have no effect, you can use an extractor. It looks like a metal rod with a screw thread and is designed specifically for unscrewing stuck bolts and screws. Before using the tool, a vertical hole is drilled with a thin drill bit in the screw. The screw end of the extractor is inserted, and firstly it is turned slowly, so that it is firmly pressed in. The screw is then unscrewed. The advantage of this method is that it does not damage the material, from which the embedded fastener is extracted. Almost all types of fasteners can be unscrewed with this method, with the exception of hardened steel self-tapping screws. It is practically impossible to drill a thin hole for the extractor in such material, the drill bit will go sideways.
Nut and wrench
Another option is to glue a nut to the top of the screw or screw. This can be done by cold welding or hot welding, if the skills allow. After curing, the screw is unscrewed with a wrench.
If the screw is so deep into the wood that there is no way to get to it, but it is necessary to extract it, you can use a cork drill. It makes neat holes and is used to remove material around a stuck fastener.
How to drive screws with a drill/driver
Types of screws
To begin with, it is worth defining what a self-tapping screw is. That’s what people call a self-tapping screw. The point is that when it is screwed into any surface, it cuts the thread itself, thus ensuring a secure hold in the material. Depending on the design features, as well as the materials of manufacture, self-tapping screws can be divided into several types.
- For wood. These fasteners are made of steel, which is strong enough for work with wood, and the external thread has a large pitch.
- On metal. Such self-tapping screws are made of steel and the finished product is hardened. Its thread has a much smaller pitch than the wood screw.
- For concrete. Here it should be stipulated that the screw can be screwed into foam concrete blocks (and the like), although there will be nothing positive about the quality of such fastening due to the low density of the material. Self-tapping screws for solid concrete has not yet been invented!
In addition, self-tapping screws differ in shape and design of the head. Depending on this, should be selected and the bit, with which the screwing will take place. The point is that if this is not done, if the screw encounters an obstacle when screwing in, the bit instead of slipping out of the screw head, turn it and break. Or if not, the bevels in the bit would break. In any case, it is not pleasant
That’s why before you screw in a self-drilling screw, you need to pay attention to the matching head and bit
As for the screwing process itself, it must be said that the technological features will differ depending on the material into which the screw is screwed.
Tools for screwing screws
Fasteners can have screw heads of different sizes and different shapes and sizes of cavities in them. So before you screw in a screwdriver, make sure that your arsenal is present screwdriver or screwdriver with a suitable nozzle. And in general it is better to have, as they say, the maximum of nozzles for the relevant tools. Plus, they should be regularly replaced, because the wear and tear of the devices in the process of operation is unavoidable.
Pay attention! The best bits are those made of tool steel with hardening additives. Do not stop at the first set you see, otherwise you will have to buy a new one after a couple of days of intensive work.
If you plan to drive one or two screws into an unstable surface, you can work with a screwdriver. But if you are going to do more than that, you cannot do without an electric screwdriver. Screwdriving with a screwdriver is not as easy as it may first look, and requires a certain amount of skill. And an electric screwdriver will do everything quickly and efficiently.
You should always bear in mind that you do not intend to use the tool for its intended purpose and, therefore, it entails certain difficulties and restrictions.
The basic rules for safe and efficient operation of a drill like an electric screwdriver:
- Follow the safety instructions. Handle the tool carefully.
- It is not necessary to screw in screws up to the end. it is fraught with a breakage of the tool, bit or screwing object. Experienced craftsmen advise to under-tighten the screws slightly and then finish by hand with a screwdriver.
- To securely fasten the bit, it is recommended to use extended bits or a specialized bit holder.
- To avoid splitting in wood, it is advisable to drill the holes in the wooden material first and only then tighten the screws.
Of course, it is better to use an electric screwdriver for such purposes, but a drill
How to remove a screw without a screwdriver
Let’s consider the most effective ways depending on the specific type of slot. Let’s start with a Phillips head.
Option No1. Phillips head screwdriver
For starters, you might notice that some screws have a hole in the head that is longer than the other. If so, you should work only with a longer recess to simplify the task. It should be added that the edges of these cavities can wear down, so work carefully, otherwise you could damage the workpiece.
One of the easiest ways is to use a coin. The method often works only with small screws. Insert the coin in the groove and then turn it counterclockwise.
If the screw is loose, you can try to unscrew it with your fingernail. The procedure is the same as in the previous method.
Take a knife, place it in the recess (long if they are different lengths) and scroll through. Be careful because if the screw is tightened too much and the knife you use is of low quality, it (the knife) can be bent and you will not obtain the desirable result.
Use an old CD. Put its edge into the groove and twist it. The CD itself might get damaged during such manipulations, so make sure you do not need it. The method definitely does not help if the screw is screwed too tight.
You can cut a long groove in the head with a metal hacksaw, but this method is only effective when the hardware is not completely screwed in. е. if the head protrudes slightly above the surface. Hold the saw at right angles to the head and saw slowly and carefully. Then, when the groove is ready, the screw can be unscrewed with a flat screwdriver or improvised means (e.g. a credit card).
Take a flat head screwdriver of appropriate size instead of a Phillips head screwdriver. What is typical, it only works with large/medium sized screws. Be careful not to tear the edge of the slot!
Another option is to use a toothbrush. Melt one end with a lighter, and then immediately insert it into the recess on the head of the screw. After waiting a short time for the melted plastic to solidify, turn the brush counterclockwise. Of course it doesn’t help if the screw is screwed too tight.
Option no2. Flat spline
As noted earlier, there is only one indentation on the head of such a screw. In the absence of a flat screwdriver, the product can be unscrewed by improvised means. Let’s see how to do this.
Use a credit card. put it in the groove and try turning it. Use only unnecessary card, because it may well be damaged in the course of unscrewing.
You can also use the “ear” of a tin can (soda pop, beer). Insert the broken off “ear” into the groove on the head of the hardware, twist it.
Use an ordinary coin. put it in the groove and try to twist it the same way.
If the screw is not too screwed in, you can try unscrewing it with your fingernail. The method is not always effective for obvious reasons.
Try to unscrew the screw with a knife by inserting the blade of the latter in the groove. There is a risk that you could bend the knife.
The last method is to use pliers. This is okay if the screw is not completely screwed in. It is preferable to use a pair of sharp-nosed pliers rather than a pair of ordinary pliers.

Screwdriver is a type of fasteners, the main feature of which is the ability to be wrapped into the material without pre-drilling. Despite the overall simplicity and ingenuousness of the design, there are many important subtleties to consider when handling them. Let’s analyze the most important and the most frequently used ones.
How to choose the right electric screwdriver bit
There are two types of Phillips bits: PH. standard with 4 slits and PZ. modified with 8 slits. The latter are good in that they actually prevent the bit from coming off the hardware during operation. When selecting a nozzle, you should also consider the size listed directly on the product. Bits come in 1, 2 and 3 sizes. The right bit ensures a secure grip.
How to screw a long self-tapping screw into hard material
In such a case, it is recommended to make a preliminary drilling, as well as lubricate the screw with paraffin or at least simple soap. Otherwise, there is a high risk of breaking the hardware or tearing off its slot.
How to correctly screw a self-tapping screw into a thin bar
The only way to avoid cracking the thin bar when screwing a screw is to make pre-drilling. It is worth considering that most often a crack appears when trying to “sink” a self-drilling screw, which means that you should countersink with a wider drill.
How to work properly with small screws
When working with small hardware, it is recommended to use a magnetized bit. If you do not have one at hand, or to make such a bit with your own hands is not possible, for fixing screws, you can use ordinary masking tape, advise consultants Novate.ru.
How to unscrew a screw with ripped off slots
It can be done in several ways. First, you can use a special extractor attachment. Secondly you can put some soft material like rubber between the self-tapping screw and the bit. Third, you can solder the bit with a soldering iron using tin if there is no other way to unscrew it.
How to unscrew a screw with a broken off head
In order to remove a screwdriver with a damaged or completely broken off head, you need to use a tubular drill bit for ceramics.
