The Fischer UltraCut FBS II US R concrete screw with its specially hardened red tip is a powerful anchoring solution for quick installation. The concrete screw with an integrated washer is ideal for outdoor applications or in damp environments. The European Technical Assessment for cracked and uncracked concrete, as well as for seismic loads and fire suitability for fire resistance class R 120, guarantees an additional level of safety. The sawtooth geometry allows for fast and energy-saving installation. No hole cleaning is required when installing in ceilings and floors. The expansion-free anchoring enables minimal edge and axis distances.

Advantages: The specially hardened red tip ensures noticeably faster and safer installation. The stainless steel version of the concrete screw provides very high corrosion protection, allowing for use in damp areas and outdoors. The special sawtooth geometry enables quick penetration into the concrete. When installed vertically (in ceilings and floors) and using hollow drills, no hole cleaning is necessary. For drilling into the ground, the hole must be drilled three times the diameter deeper. The ETA assessment covers applications in cracked concrete as well as seismic performance categories C1 and C2. The approval-compliant adjustment allows the concrete screw to be loosened twice, enabling the attachment to be shimmed and/or aligned. Three approved screw-in depths allow for use in a wide range of applications, providing great flexibility. The short version with reduced screw-in depth enables a shallow hole depth, quick installation, and fewer reinforcement hits.
