fischer concrete screw FBS M6/9 with external thread 5x45

The fischer concrete screw FBS 5 stud screw is made of zinc-plated steel with an external thread. The FBS 5 stud screw is perfectly designed for applications such as fastening rail systems, electrical installations, and installations in general, as well as for DIY applications. When the concrete screw is driven in, the thread flanks cut deeply into the concrete, ensuring a high load-bearing capacity. The shallow drilling depth saves time during installation. The recommended loads for cracked and non-cracked concrete, as well as suitability for masonry such as calcium silicate brick, and the classification in fire resistance class R120, all ensure safety.
