PowerFull FIF-ZT ZPF

The fischer double-threaded screw PowerFull FIF-ST ZPF with cylinder head and TX star recess socket is ideal for the fixing of non-pressure-resistant insulation materials in rooftop insulation. The TX star recess drive enables top force transmission with maximum bit stability. The thread geometry offers optimum force transmission. The European Technical Approval guarantees added safety. The geometry of the screw tip enables screwing without pre-drilling. The large thread pitch results in noticeably faster screwing times. The slim cylinder head reduces the formation of fissures, and no cracks form when screws are inserted close to edges.
