First of all, first of all, tools

Reliable fixing the structure. A guarantee that it will last a long time, without requiring additional repair

In this regard, it is very important to choose reliable tools and fastening elements. And this choice needs to be approached with all responsibility

You will need special tools. Shock drill is best.

You can choose the usual drill, to which the winning tip is selected. But in this case, work will be complicated. At the cost of this, this will result in approximately the following numbers: from 800 for the tool itself and from 40 to 50 in addition to the drill. Chassis are considered diameters for 6 and 8 mm.

A list of materials with which such tools can work is extensive. Their choice will depend on the future load of the hinged structure. The most popular are the following:

  • Self.Tapping screws for bricks;
  • Dowels (help withstand a large load);
  • Anchors (capable of keeping very heavy things on themselves);
  • Rivets (for delicate glass shelves);
  • Corners (for small cabinets and shelves);
  • Ordinary nails combined with everyone else.

It is also important to consider which product is used to lay the surface. It can be both whole and hollow. The types and varieties of this product will also tell you how reliable the screws used for bricks are

The main rules for fastening

Before starting work, some rules must be learned. They will help not to spoil the surface and carry out the right fastener:

  • The most basic requirement that needs to be fulfilled when attaching something on a wall of such a material is not to spoil the solution that fastens the blocks.
  • It will be best to use the drill. It will help to avoid cracks that may appear if, for example, with a pedorator to try to “plant” self.Tapping screws into a brick.
  • Drilling should be unhurried and gradual. This approach will help to fix any element into a similar wall.

There are several ways that will help to facilitate work with the placement of fasteners on such a wall. Some of them are happy:

If we work with dowel-bves. It is important to prepare a container with water. In it we will periodically cool the drill. On the drill itself, you can wound an island, which will serve as a limiter

After the hole is ready, insert the glass of the dowel and score a nail. In order to facilitate the process. Which the screws scored in the brick pass, you can use the “old” method. The dowel inserted into the drilled hole is strengthened using a wooden peg. Another “grandfather” method will be that a hole is drilled, a cork or chopic is twisted into it, previously soaked in PVA’s gap. Then the “excess” walls peeping from the wall is cut and the self.Tapping screw is screwed. But such a mount is considered short.Lived. It is best to use dowels for work. Intended specifically for the brick wall. They have ledges that will not allow him to cream, even if a screw or a nail is screwed. This rule acts even for hollow bricks, in which it will turn into the knot and will take all the necessary volume. Когда требуется оформить наружную стену (например, вход дома), можно наряду с дюбелями и саморезами можно использовать уголки. They will not only connect the structure and wall, but will even become supporting elements.

What kind of screw to choose for work

The selection of screws by the type of cut on them is small: they can be universal or on a tree, which has a much larger step.

If you have to screw a screwdriver, a wood-cutting plate or plywood in the process, feel free to purchase universal products. If the work is with a tree, then only those that are intended for this material are suitable for this. Why, you ask. The answer is simple. In order for the fixation to be reliable, the material must reliably “lay down” between the threads of the thread. The wood structure cannot do this if the thread step is too small.

How to screw a self.Tapping screw without drilling

Not every novice builder knows how to tighten the fasteners into the wall without preliminary drilling the hole. This operation is optional for working with aerated concrete or expanded clay concrete.

To consolidate any products on the walls from these materials, special screws with dowels are used. In this case, the seal should be made of polypropylene, kapron, cellophane. During the twisting of such a fastener element, the seal is delays, more strongly adheses with the wall.

The self.Tapping screw itself is screwed with a conventional screwdriver or rattle with a cross.Cut. In this case, it is necessary to make a significant effort.

Assortment and size

There are several types of designs of this material. They are divided into hexagonal and rectangular.

Hexagonal self.Tapping screws for concrete are a cone.Shaped or cross.Shaped shape of a slot. This type of screws is screwed using a uniform or rock key. A rectangular look is characterized by a rounded head, such a feature of the product allows you to hang hanging structures on screws.

These types of fastening are sold in all construction stores. It is better not to take the goods in the markets, t.To. Often, sellers deceive buyers who do not understand products of this type.

Self.Tapping screws also differ in the processing method, which is the following types:

The darkened type of screws are the most fragile, t.To. Sensitable to moisture. For this reason, it is not recommended to use this type of product in places with high humidity. Rivets with copper coating are sensitive to temperature fluctuations. For this reason, they are used only in rooms. The most common model is galvanized screws, this type can be used in any conditions.

To choose mounting material for the concrete wall, a number of parameters should be taken into account. For example, the height of the head should be entered in the range from 2.8 to 3.2 mm. The diameter of the hat should be 10.8-11.8 mm. Depth. From 2.3 to 2.8 mm. Self.Cut length can be in the range from 5 to 18.5 cm.

The size of the internal section is 5.1-5.5 mm, and the external section is laid in the framework of 7.3-7.7 mm. The outer diameter is 6.3-6.6 mm.

General information

There is a wrong opinion that.

Universal details are perfect for wood, and for woody stove, and for plywood, and will be no worse than specialized. Yes, of course, it will not be difficult to screw them into such materials, but how well they will hold on is another question. The fact is that the material in which the self.Tapping screw will be screwed should reliably run in the thread grooves, and the wood structure will not make it possible to place it normally in the narrow screw grooves of the element of the universal type fastening element.

Tools for screwing

The mounts can be with hats of different sizes and different in shape-sizes of recesses in them. For this reason, before entering a self.Tapping screw, you should make sure that your arsenal has a screwdriver or even an electric screwdriver with a suitable nozzle. But in general it is worth having as many nozzles as possible for appropriate tools. In addition, their regular replacement should be carried out, because when used in any way cannot be avoided.

Self Drilling Screw. Discussion

Self-tapping vs Self-drilling Screws

Please note that optimal nozzles are those that are made of instrumental steel with additives for hardening. Do not opt ​​for the first device that fall, since otherwise after 2-3 days of permanent work you will need to buy a new.

If you have plans to tighten 1-2 self-tapping screws in unsteady surfaces in your plans, then you can perform work using a screwdriver. If we are talking about more, then you can’t do without an electric screwdriver. Twisting the mount by means of a screwdriver is not the simplest operation, as it may seem at first glance, and a certain dexterity is required. But with the help of an electric screwdriver, you can do everything efficiently and quickly.


For the manufacture of concrete screws that can be screwed without drilling, a special hardened steel is used. This composition gives the product high strength. A zinc coating is applied on top of such steel. This combination allows you to improve not only the mechanical qualities of the product, but also give the fasteners an anti.Corrosion property.

Self.Tapping screws that have a cross.Shaped helmet can be screwed without problems using a screwdriver. Products that are marked as Torx, with hinges, protruding heads or external carvings, as well as a 6-sided head, needs to use special tools designed for this type of screws.

If there is an uneven cutting of thread on the fasteners, then the adhesion with concrete is stronger than with uniform. This is due to the fact that there are special cuts on fasteners. Such designs are well held even on porous walls and in blocks with an empty inside.

Drilling holes in concrete

If the drilling of a concrete wall is carried out by a peorator or drill with a shock function, then you should refuse a drill with attack. The baptism will simply disappear from the blows. It is better to use a pedorator drill. It has longitudinal grooves on its surface. When drilling, the working tool is very heated. To avoid overheating and failure of the drill, it must be periodically wetted with water. The depth of the hole should be equal to the length of the screw.

You can do without a drill and a penetrator at all, if you take an old drill of the desired diameter. It needs to be put on the wall and apply 2-3 beats with a hammer. After that, turn the drill in the hole and repeat all the operations until the necessary depth is reached. It remains only to remove garbage from the hole. It is not easy to do it. You can blow strongly in the hole, having previously closed your eyes.

Further, the self.Tapping screw can be tightened by inserting a match into the hole for the strength of the mounting. It is not recommended to tighten it with an electric screwdriver, which has a high speed of rotation. Electric screwdriver cannot be stopped in the right place. It will definitely turn and weaken the screw mounting. It is better to screw it with a regular hand screwdriver. You can hang a mirror, shelf or picture on a screwed self.Tapping screw.

This was the easiest option for doing work. Consider a few other options.

screw, self, tapping, drill, screws

Concrete is a very durable building material. Installing fasteners for hanging cabinets or other items on it is not very simple. There are many devices and tools for this purpose. The most popular of them are self.Tapping screws. With the right choice, there are no special problems in the installation of hinged structures. Self.Tapping screws in stores are presented in huge numbers. They differ from each other in color, size, thread, material of manufacture. Most often they are equipped with plastic dowels (photo), which provide tight fixation of the screw in the wall (photo).

Self.Tapping screws with a “Christmas tree” type cannot be twisted back. But they should not screw. They are simply clogged with strong hammer blows. The diameter of the screw for concrete is 3-6 mm. Their length ranges between 12 and 220 mm. Fasteners with dowels need to be selected correctly. The dowel must enter the hole completely and tightly. There are fasteners with variable threads (photo), which expands the hole, and the upper part fixes the fasteners in the wall.

Most of concrete fasteners are made of steel with carbon. From corrosion steel is protected in various ways. The following types of protective coating are often found:

Galled parts have a characteristic silver shine. This coating today is the most durable. It is used both on the street and inside any room. Oxidized products have black color (photo). They are subjected to special ink, as a result of which a protective film is formed on the surface. This oxide film prevents from rust. Oxidated products are used in conditions of normal humidity. Clushed screws are covered with brass or copper. They have yellow and are used to produce internal work.

Advantages of self.Tapping screws

The concrete structure is a conglomerate consisting of granules of aggregates, cement stone, small and large pores. To firmly fix the part, the thread of the rod is formed along the entire length of the nagel. This is especially important for light foam and aerated concrete, where the voids occupy a significant part of the volume, and the tearing force is perceived by fragile porous walls.

Use of awl and self.Tapping screws

Shilo is a universal tool that is able to help in many situations related to repairs, including this.

First you will need to take a pencil, measure and mark the place where you want to make a hole. To begin with, there will be a fairly simple point, since the awl in itself is thin. If there was no awl at hand either, you can try to carry out the same operation with a nail, gently driving it with a hammer.

It is necessary to nail thin or medium so as not to damage the surface of the wall. It is necessary to drive it to the end, because then it will be difficult to pull it out. The length of the nail directly depends on the required depth of the hole, but initially the hole should be made somewhat shorter.

Then this point on the wall must be taped to the desired depth. The latter directly depends on your goals for which the hole is intended. This ends with Shil, then self.Tapping screws are used.

Since the thickness of the awl is minimal, it is not able to make a wide hole, but it was it that paved the path to further action. After we take the thinnest self.Tapping screw, which is screwed into an existing hole and pull it back.

The following will require a larger self.Tapping screw, with which it is necessary to do exactly the same manipulation. Instead of self.Tapping screws, you can also use large screws in diameter.

Thus, it is possible to get a hole whose diameter does not exceed the diameter of the largest self.Tapping screw or screw. If you need a larger hole, in this case you should resort to the use of the drill.

It must be inserted into an existing hole and twisted with pliers, while pressing on the drill itself with a hand from above.
