The powerful concrete screw for maximum installation comfort outdoors.

The fischer concrete screw ULTRACUT FBS II US R, featuring a specially hardened red tip, is a high-performance anchoring solution for quick installation. The concrete screw with the attached washer is ideal for outdoor applications or in damp areas. 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 quick and energy-saving installation. No hole cleaning is required when installing in ceilings and floors. The expansion pressure-free anchoring enables minimal edge and axis distances.

Product advantages: specially hardened red tip, hexagon with washer, very high corrosion protection, suitable for use in damp areas and outdoors, quick screwing in due to special sawtooth geometry, underhead ribs securely prevent unintentional loosening, up to three nominal screw-in depths per diameter. The ETA assessment (ETA-17/0740) covers applications in cracked concrete (Option 1) as well as seismic performance categories C1 and C2. The approval-compliant adjustment allows the concrete screw to be loosened up to 20 mm twice, to place and/or align the attachment component. The expansion pressure-free anchoring (undercut) ensures minimal edge and axis distances. With the screw head resting on the attachment component, correct screw installation is guaranteed (visual setting control). R - stainless steel of corrosion resistance class III.

Note: For vertical installation (in ceilings and floors) and when using hollow drills with suction, hole cleaning is not required. When drilling into the ground, it is necessary to drill 3 times the drill diameter deeper.
