The powerful concrete screw for maximum installation comfort outdoors.

The Fischer concrete screw Ultracut FBS II SK R, featuring a specially hardened red tip, is a high-performance anchoring solution for quick installation. The concrete screw 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, ensures 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.

Product 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. For drilling into the ground, it is required to drill three times the drill diameter deeper. The ETA approval 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 by up to 20 mm, enabling the attachment to be shimmed and/or aligned. R - stainless steel of corrosion resistance class III.

Note: For vertical installation (in ceilings and floors) and when using hollow drills with suction, no hole cleaning is necessary. For drilling into the ground, it is required to drill three times the drill diameter deeper.

Caution: The manufacturer refers to the drill diameter in the item designation and not to the screw diameter.
