The fischer GKM is screwed directly into plasterboard and gypsum fibreboards, sitting flush with the surface. Its sharp, self-tapping thread ensures a secure and positive fit, leading to high load-bearing capacity. This fixing is compatible with wood, sheet metal, and chipboard screws ranging from 4 to 5 mm in thickness, as well as various hooks and eye screws. It is therefore universally suitable for quickly and securely fixing items such as lights, electrical installations, and accessories. Each pack contains 100 fixings and includes a PZ2 screw bit.
