The Fischer concrete screw UltraCut FBS II SK R with its specially hardened red tip is a powerful anchoring solution for quick installation. The concrete screw with the pressed washer is ideal for outdoor applications or in damp areas. The European Technical Assessment for cracked and non-cracked 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 pressure-free anchoring enables minimal edge and axial 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 cutting into the concrete. For vertical installation (in ceilings and floors) and when using hollow drills, no hole cleaning is necessary. When drilling into the ground, it must be drilled three times the drill 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 allows for a shallow drill hole depth, quick installation, and fewer reinforcement hits.
