ART 9001-B A4 hexagon head Screw with flange

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;

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.
