Internal thread wall bolt (metric)

The cost-effective anchoring solution with internal thread

The fischer wall bolt FWB is a zinc-plated steel anchor. The FWB is ideal for safely fixing temporary anchors, cantilevers, and handrails in non-cracked concrete. The internal threaded anchor is set in a pre-positioned installation. When the screw or threaded rod is tightened, the cone is pulled into the expansion sleeve and expands against the drill hole wall. The metric internal thread allows for the use of conventional screws or threaded rods. This increases flexibility and reduces costs. The anchor construction also enables complete disassembly.
