Often there is a need to screw the screw into the concrete wall.

Concrete and reinforced concrete is the most popularBuilding material. Therefore, many are interested in how to tighten the screws in them correctly. Most often, concrete is used for building the foundation of a building, erecting walls and interior partitions. Due to its high strength, concrete structures are recognized as the most durable.

Types of screws for concrete

Among the most common screws for concrete is:
- with countersunk head-
- with a cylindrical head.

Screws of the first type are made of steel,Which is applied a thin layer of zinc, which provides protection of the product against corrosion. Use such a screw can be without a dowel, as its full thread provides strength of fastening.

When there are cavities in the concrete wall, a flared or impact dowel is used.

Fastening of a screw to a concrete wall

Concrete is much stronger than all other building materialsMaterials, therefore for its drilling it is necessary to use a special drill, which is a product, on the end of which there is a carbide insert.

As for the instrument, it is bestTo use an impact drill, if it is not possible to purchase it, the work can be done with a conventional drill. But in this case it will be difficult to drill, but also to rotate during this drill around its axis. Otherwise, concrete may not succumb.

To begin with, the wall of the future hole is marked and only after that it can be started drilling. The depth of the hole must correspond to the length of the screw.

The drill becomes very hot during operation. So that it does not overheat, it must be moistened with water.

After making a small depression, a pre-prepared pin is driven into the hole and turns. Thus, you need to act until the required depth is obtained.

From the hole made, all dust and debris is removed. After this, a dowel and a screw is inserted into it.

The screw, like the screw, is screwed with a screwdriver, you can not do it with a screwdriver. Otherwise, it may just fall out after it has rested against the end of the hole.

If a concrete wall is to be attachedAn easy object, then you can use a plastic dowel shock and a drill bit winner. The diameter of the dowel and the drill must be 6 mm. The length of the dowel is selected depending on the thickness of the wall of the object, which is planned to be fixed.

To attach objects weighing from 5 to 10 kg to a concrete wall, a 8 mm diameter impact plug and a drill with the same diameter are used. The number of dowels is not less than four.

Fastening of heavy objects, such as suspensionCabinets, stands for televisions, should be carried out using dowels with a diameter of 10 mm and a ten-millimeter drill. To ensure a stronger fixation, at least six dowels are required.
