Fischer Concrete Screw UltraCut FBS II US R The specially hardened red tip provides a faster and more secure installation. The stainless steel concrete screw guarantees a high level of corrosion resistance especially for wet rooms and external applications. The approved adjustment for the concrete screws allows the screw to be unscrewed twice to align the attached part, and then to tighten the screw again. The fischer concrete screws FBS II 6-10 offer the innovative possibility for the ETA compliant application in masonry. This grants high security not only in concrete but also in many other applications in other substrates. The fischer concrete screw UltraCut FBS II US R, with the specially hardened red tip is a high-performance anchoring solution for fast installation. The concrete screw with the pressed washer is ideal for applications outside or in damp areas. 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 expansion-free anchorage (undercut) ensures low edge and axial spacings. Applications Guard rails Consoles/Base plates Metal profiles Steel constructions Façades Protection barriers Building Materials Approved for: Concrete C20/25 to C50/60, cracked and non-cracked Bricks of clay (EN771-1) Solid sand-lime brick (EN771-2) Perforated sand-lime brick (EN771-2) Approved for: ETA-20/0134 ETA-17/0740 DoP No. 0311 DoP No. 0344 Installation The UltraCut FBS II R is recommended for the push-through installation. Drill holes do not need to be cleaned during vertical installation (ceiling and floor). For floor fixings the hole must be drilled 3x drill hole diameter deeper. We recommend using a tangential impact screwdriver with a suitable impact screwdriver socket or an internal TX drive. The screw is installed correctly when the screw head sits flush on the fixture and cannot be screwed in deeper (visual setting control).
