Concrete Screw Concrete screw FBS 6 SK

The versatile screw solution for fast and simple installation

The fischer concrete screw FBS 6 SK is an anchoring solution with a countersunk head. The zinc-plated steel design enables use for visually demanding anchorings inside. When the concrete screw is screwed into the drill hole using an impact driver, the thread flanks cut into the concrete in a positive-locking manner, thus ensuring top load-bearing capacity. The low drilling effort saves time in the case of multiple fixations.
