At what speed to tighten the screws with an electric screwdriver

Classification

This fastener is available in a variety of materials such as brass, stainless steel and carbon steel. Also, self-tapping screws have different coatings, such as:

• galvanized (yellow);
• oxidized black;
• phosphated black;
• without cover.
• semi-cylindrical;
• secret;
• hex;
• hemispherical.

Black self-tapping screws

The use of this or that self-tapping screw depends on the density of the material that you plan to fasten. Therefore, before buying this product, you need to decide on the following:

• Connection conditions.
• Is it necessary to drill a hole before screwing.
• What material do you need to screw it into?
• What material will be attached.

Starting from this, you make the appropriate choice, whether it will be a self-tapping screw for metal, wood or for concrete.

Cross PZ and PH

In the vast majority of cases, self-tapping screws are tightened with Phillips screwdrivers or bits. But even among the usual cross bits there are two different standards, professionals know this, but many amateurs do not. In short, the first slot was Ph, I will not go into history, just say that the name is an abbreviation for Phillips. When the patent license came to an end, Phillips, the same company that patented the Ph slot, released a more improved version, the Pz slot, or expanded Pozidriv. Let’s briefly understand the differences between these two standards:

• The main difference is that the Ph bit has four faces. The Pz bit has four main faces, and four additional, in total eight, against the four faces of the old standard.
• The Ph bit has a tip sharpening angle of 55˚, and the Pz bit has the same angle of 50˚. As a result, the new version “sits” much deeper on the slot.
• The edges of the working surface Ph of the slot are inclined at an angle of 12˚, and for Pz these edges are parallel to each other, as a result, the bit does not jump out of the slot, as is the case with Ph.

Why am I doing this? Until now, many self-tapping screws with the old Ph standard are produced, despite all the advantages of the new Pz standard. In principle, with a Ph bat, you can screw a self-tapping screw with a PZ face, and in the reverse order (even with a better result), a PZ bit can screw a self-tapping screw with a Ph slot quite well. But you need to clearly understand that these are different standards, and they are not completely interchangeable. This means that by using the wrong bit, we are simply shortening its life. details about all types of bits and splines can be found in the publication: “Bits for an electric screwdriver: marking, varieties, classification”

How to tighten self-tapping screws with an electric screwdriver

How to screw a self-tapping screw into a tree with an electric screwdriver.

Even a person far from this business can handle screwing a self-tapping screw into a tree with an electric screwdriver, since an electric screwdriver will do all the work for you, you just need to choose the right attachment for an electric screwdriver (bit). The rules that must be followed when choosing bits for screwing self-tapping screws into a tree are the same as when choosing a screwdriver.

How to properly tighten the unscrewed self-tapping screw?

The unscrewed part must be re-tightened exactly as it stood before. It is very important that the screw goes into the same groove, at the same angle. If the product “draws” a “new path” for itself, the reliability of the fastening will be significantly reduced. How to get into an already existing groove? Just insert the part into the hole and turn it by hand without pressure. As soon as everything falls into place, you will feel it. the process will go like clockwork. You do not need to press on a tight self-tapping screw, you just need to remove it and try again. A little effort is required only at the very end of screwing.

Now you know how to screw a self-tapping screw into drywall, concrete, brick, wood and metals correctly and what to do in case of “work hitches”.

It is impossible to do without fasteners in construction today. They allow you to connect different building materials, hang objects, strengthen certain structures, and more. One of the most common fasteners is the self-tapping screw. This product has an external thread and a head. The thread is comparatively sharp so that in some materials it can cut internal threads by itself. This article will discuss how to screw a self-tapping screw into a variety of materials. But first, let’s figure out the classification of these products.

How to screw screws into different materials?

Many men, not knowing how to screw a self-tapping screw into concrete, spoil a sufficient number of purchased parts. In fact, everything is quite simple: self-tapping screws are “integrated” into concrete with the help of dowels. strong plastic “tubes”. First, a hole is made in the material, a dowel is installed there, which “receives” the fastener.

Worth knowing! Craftsmen advise to grease the dowels with glue before installing. This, in their opinion, strengthens the connections.

Drilling holes in concrete should be done exclusively with a hammer drill. even a hammer drill may not withstand, let alone a conventional one. Self-tapping screws are suitable for both wood and universal.

Self-tapping screws are screwed into these environments in the same way as into concrete. The only thing is, for working with tiles, it is better to take an ordinary drill, since it can crack from the excessive power of the hammer drill.

Measure the shank diameter of the fastener excluding threads. This manipulation must be performed with a caliper. Install the pointed jaws perpendicular to the self-tapping screw and clamp the product so that they completely penetrate the thread groove; determine the diameter. With a drill with a diameter of one and a half millimeters smaller than the obtained value, make a hole in the material. Screw the self-tapping screw into the hole. and the job is done. Use parts with a universal thread.

Note! Before “piercing” the main structure, it is recommended to check the drill on a small unnecessary piece of similar material. Drill a hole and try to screw the product in there. The drill is considered correctly selected if the self-tapping screw goes into the hole tight enough, but does not jam. In the event that the screw fails to “break through”, you should work with a thicker drill. Too light twisting of the part symbolizes that you need to take a thinner drill. otherwise the self-tapping screw can pop out at any time.

The hole in the material must be equal to or slightly larger than the unthreaded bar diameter. Self-tapping screws will not be able to cope with a number of hard metals. in particular, it is almost impossible to screw these fasteners into cast iron.

Not every plastic is ready to accept a self-tapping screw, so it will not be superfluous to make sure before starting work that the material fits exactly. The technology for screwing a self-tapping screw into plastic is the same as for soft metals. copper, aluminum, bronze. Featured Products. Wood Carved.

Don’t know how to screw a self-tapping screw into the board? Believe me, nothing is easier. The basic rule is to use only wood screws. For hard woods, thin boards, Particleboard, Fiberboard, pre-drilling a hole for the product is mandatory, as there is a risk of splitting the material with a self-tapping screw. For thick softwood boards, this manipulation can be dispensed with.

• with hard wood. choose a drill with a diameter equal to the diameter of the self-tapping rod (naturally, no thread);
• with Fiberboard. 1 millimeter less;
• with particle board or softwood. 2-3 millimeters less.

Mark points on the sheet with a pencil. The optimal pitch between screws is up to 70 centimeters, depending on the expected loads on the structure. If you are using an electric screwdriver, you can start screwing the product at maximum speed. After the self-tapping screw enters the surface by ½ it is recommended to gradually reduce the speed to the minimum. When tightening with an ordinary screwdriver, all movements should be smooth. It is very important to tighten the self-tapping screw correctly. ideally, it should be 1 millimeter below the level of the cardboard, not gypsum! This will ensure maximum strength of the future structure. If you suddenly did not follow the technology and broke through the cardboard, the “ill-fated” place needs to be putty, and a new fastener should be placed at a distance of 5-9 centimeters from it.

The type of self-tapping screws for drywall must be selected depending on the material used in the construction of the sheathing. For the metal frame, universal or metal self-tapping screws are required, for wooden lathing. wood products.

Into the tree

As for the tree, everything is very simple here. The only restrictions may be imposed by the type of wood used. If it is soft, you do not need to pre-drill the hole. If the workpiece is made of particle board or fiberboard, it is better to drill a hole. over, it is recommended to drill a hole in cases where it is necessary to tighten a long self-tapping screw on wood. This applies even to soft wood.

When making a hole, its diameter should be smaller than that of a self-tapping screw. This will ensure reliable fastening of the workpieces.

In addition, the hole should be made even in cases where the wood workpiece is relatively thin and there is a risk of splitting. When screwing the self-tapping screw into such parts, you need to be careful.

When screwing in, the cap should sink into the wood. If this is a finished floor, then all holes must be covered with wood putty.

Concrete

Concrete is a hard surface into which it is difficult to screw a self-tapping screw. Therefore, before screwing the self-tapping screw into concrete, it is necessary to prepare the dowels. Thanks to these auxiliary parts, an excellent fixation of the fasteners is ensured.

First, drill a small hole in the surface, holding the tool perpendicular to its plane. The resulting nest, of course, is well cleaned of dust using a special pump. If not available, you can use a regular bicycle pump or juice tube and tissue. It is not recommended to clean the hole with simple back and forth movements of the drill. If this is not done, then the dowel will not be able to enter the hole in its entire length. Also, a poorly cleaned hole may not give sufficient adhesion of the dowel to the inner walls, after screwing in the self-tapping screw.

After that, a dowel is inserted into the prepared hole. The self-tapping screw is screwed into the inside of the dowel using a screwdriver or an electric screwdriver.

Wood, Fiberboard and Particleboard

Before screwing the self-tapping screws into the wood, make sure that they are designed for working with wood. Before the procedure, holes should be drilled in the wood. This rule applies to particle board and fibreboard. If you start screwing in the self-tapping screw right away, then there is a chance that the material will crack.

The first step is to drill a small hole in the wood. Its diameter should be less than the diameter of the self-tapping screw. After that, the self-tapping screw itself is screwed into the wood with an electric screwdriver at medium speed.

Many people believe that universal self-tapping screws are suitable for screwing into wood, chipboard or plywood. However, this is a misconception. The fact is that the material, which includes the hardware, must be firmly positioned in the grooves. The internal structure of the wood does not allow the narrow thread of the universal self-tapping screw to properly lay in it.

How to screw in self-tapping screws correctly

Many people during the repair cannot do without the use of self-tapping screws. In inept hands, they often break and bend. This usually happens due to ignorance of the technique of working with them. Consider how to choose, as well as how to properly screw the screws into a particular material.

Screwing screws into different materials

Few people know how to properly screw screws into different materials. Consider the process of screwing screws into concrete, metal, wood and drywall.

Screw-in technology

Before turning the screws, it is necessary to make a small indentation in the place intended for the screw. After that, the self-tapping screw is installed inside the hole made, and twist it until it completely enters the material and is fixed in it. During operation, increase the screwing force. Closer to the end of the “process”, the twisting speed is reduced so as not to damage the screw head.

Metal (bronze, aluminum)

Before screwing the self-tapping screw into the metal surface, you should measure the diameter of the “screw” without taking into account the thread. To do this, use a caliper. After that, you need to take a drill with a diameter of 1-1.5 mm less than the obtained value and make a hole in the metal with it. The last step is to screw the self-tapping screw into the hole with an electric screwdriver at medium tool speed.

Advice! To achieve the best result, it is worth practicing in advance on metal blanks.

How to choose a self-tapping screw?

Self-tapping screws are fasteners that are rods with a head and a thread. Hardware are designed to connect elements of wood, plastic and metal.

There are 2 types of self-tapping screws that are often used for repairs. The first type of product is universal, and the second is designed for woodworking. Hardware differ in thread pitch. For products intended for wood, threads are rarely located.

What tools are needed to work with self-tapping screws?

Before screwing in the self-tapping screw, you should pay attention to the presence of a screwdriver or an electric screwdriver with nozzles in the house.

• Hand screwdriver. Used to drive small screws into plastic or wood. It is also convenient to use a screwdriver to connect parts that already have a hole.
• an electric screwdriver. a tool that allows you to screw fasteners into both metal and wood without much effort.

Important! Electric screwdriver bits must be made of tool steel.

Instruments

The thing is that home craftsmen often do not know how to screw in a self-tapping screw correctly and how to choose it correctly.

There are two main types of self-tapping screws used for self-repair. for wood and universal. Their main difference is in the thread pitch. “screws” for wood are characterized by a large pitch (less frequent threading).

How to drive screws with a drill/driver

There is a misconception that versatile parts are just as good for wood, plywood and chipboard as custom parts. No, of course, it will not be difficult to screw them into these materials, but how well they will stick there is a big question. The fact is that the “raw material” into which the self-tapping screw is “immersed” must reliably lie in the grooves of the thread, and the structure of the wood will not allow it to fit qualitatively in the narrow “grooves” of the universal self-tapping screw.

Self-tapping tools

Fasteners can have caps of different sizes and recesses in them of various shapes and sizes. Therefore, before screwing in the self-tapping screw, make sure that you have a screwdriver or screwdriver with a suitable attachment in your arsenal. In general, it is better to have nozzles for the corresponding tools, as they say, to the maximum. Plus, they should be replaced regularly, since the wear of the devices during operation cannot be avoided.

Note! The best bits are those made of tool steel with hardening additives. Do not stop your choice on the first set that comes across, otherwise after a couple of days of intensive work you will have to go for a new one.

If your plans include screwing one or two self-tapping screws into an unstable surface, then you can work with a screwdriver. If it is more, you cannot do without an electric screwdriver. Tightening fasteners with a screwdriver is not as easy as it might seem at first glance, and requires some skill. And an electric screwdriver will do everything quickly and efficiently.

General screwing technology for self-tapping screws

Use an awl to make a small indentation in the place reserved for the self-tapping screw. Install the product “on position”. Use careful but firm movements to rotate the part until it deeply deepens and locks in the material. Then the force can be increased. Towards the end of the “process”, the speed must be reduced again. so as not to damage the self-tapping screw.
