Drill, screw in, done

The concrete screw anchor is an innovative anchoring system for securing assembly parts to concrete and other solid masonry. With its cutting-teeth design, the concrete screw anchor cuts a thread in the drill hole as it is screwed in, creating a connection with positive locking and no expansion pressure.

The original self tapping anchor, can be used on a whole range of construction materials including stone, brick and block.
The threaded anchor and self tapping action, allows for self anchorge, with the substrate becoming the nut to the bolt.
Quick and easy installation.
Can be installed nearer to the edge and closer together.
Completely removable, so ideal for temporary jobs.
