Concrete screw FBS II 6x85/25 US A4

The fischer UltraCut FBS II 6 R is a powerful and fast anchoring solution for outdoor applications and damp environments. The specially hardened screw tip ensures faster and more secure installation, while the thread design cuts deeply into the concrete, increasing tensile and shear strength. The stainless steel screw offers excellent corrosion resistance.

Approvals (ETA Option 1 and Part 6) allow use in both cracked and non-cracked concrete, as well as in seismic areas (C1), providing top-level safety. The screw is suitable for both pre-positioned and push-through installations. Installation is effortless — no hole cleaning is required in ceilings and floors, and correct installation is ensured when the screw head is flush with the attached part.

The UltraCut FBS II 6 R also features an approved adjustment option: the screw can be unscrewed and retightened twice with a total adjustment distance of 20 mm, allowing up to 10 mm shims to be inserted or the attached part to be aligned. The expansion-free anchorage enables small edge and axial distances, and the underhead fluting prevents loosening of the screw.
