The fischer concrete screw ULTRACUT FBS II is a powerful anchoring solution with top installation comfort. The European Technical Approval for cracked concrete and non-cracked concrete as well as for seismic loads and classification into fire resistance class R 120 guarantee even more safety. The saw tooth geometry enables a quick and easy installation. No drill hole cleaning is required for installation in ceilings and floors. The concrete screw is ideal for the fixing of railings, cantilevers, and shelving systems inside. The ULTRACUT FBS II is made from zinc-plated steel (diameter 6-14) or stainless steel (diameter 8-12) and is offered with a countersunk head, Torx-drive and hexagonal head, and with or without a torque drive (only for gvz) as desired.
