Screws made of a first type of steel,which is a thin layer of zinc protects the product against corrosion. Use a screw without a dowel can be, as it provides a full thread tightness.
In the presence of voids in the concrete wall using expanded or stroke dowels.
Fixing screws concrete wall
Concrete is much stronger than the rest of the buildingmaterials, so it should use a special drill bit, which is a product, at the end of which there is a carbide insert.
As for the tool, it is bestuse a hammer drill, if its purchase is not possible, the work can be carried out by a conventional drill. But in this case it is necessary to drill hard but also rotated during this drill around its axis. Otherwise, the concrete can not succumb.
To get started in the wall marked the future location holes and only after that he can start drilling. Hole depth should correspond to the length of the screw.
Drill during extremely hot. For it is not overheated, it should be moistened with water.
Make a small indentation in the hole prepared beforehand hammered pin and rotated. Thus, you need to do to obtain the required depth.
From caved removes all dust and debris. After that, it is inserted into the dowel and screw.

Mounting heavy objects, such as suspensioncabinets, stands for televisions, should be carried out with the help of dowels 10 mm diameter drill desyatimillimetrovym. To provide a more durable attachment will need at least six dowels.
