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, TX-drive and hexagonal head, and with or without a TX-drive (only for gvz) as desired.
