ART 9001-C A4 Screw on concrete under a hexagonal key

Concrete screws with the most round head - are designed for quick installation of structures to the concrete base. They do not create stress in the material, because they do not have expandable parts, which allows you to make close to the edge of the concrete slabs mounting points. They can also be unscrewed several times and screwed into the same hole that allows you to make adjustments, setting the level of the part to be fixed; Due to the fact that it has a threaded metric end instead of a cap, the parts that will be fastened with such a screw can be removed at any time and re-fixed with the appropriate nuts and washers, without dismantling the screw itself. It also allows, if necessary, to mount the part at a certain distance from the base.

Usage screws can withstand very high loads on the breakout: break out, only with a piece of concrete;

Material grade A4 steel from which they are made guarantees absolute corrosion resistance of the mounting point and is ideal for fixing aluminum structures.
