CONCRETE SCREW FISCHER FBS II 6X85/25 SK R CSK A4

The fischer UltraCut FBS II 6 R is an efficient and fast fastening solution for outdoor use and damp environments. The specially hardened screw tip ensures faster and more secure installation, while the thread design enables deep cutting into concrete, enhancing tensile strength and shear resistance. The stainless steel screw offers excellent resistance to corrosion. Approvals (ETA Option 1 and Part 6) enable use in cracked and uncracked concrete as well as in seismic zones (C1), providing top-tier safety. The screw is suitable for both pre-installed and through-installation. Installation is effortless—no hole cleaning is required in roof or floor structures, and correct installation is confirmed when the screw head is flush with the attached component. The UltraCut FBS II 6 R also features an approved adjustment capability: the screw can be opened and re-tightened twice over a total travel distance of 20 mm, allowing the use of up to 10 mm shims or correction of the attached component. The non-expanding fastening enables small edge and axial distances, and the undercuts prevent the screw from loosening.
