Fischer 558229

The Fischer Ultracut FBS II is the concrete screw designed for maximum installation comfort.

The countersunk head design allows for use in visually demanding anchoring applications. 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 enables quick and energy-saving installation. No hole cleaning is required when installing in ceilings and floors. The expansion pressure-free anchoring allows for minimal edge and axis distances.

Product advantages: maximum flexibility in load and component thickness due to up to three approved screw-in depths. The special sawtooth geometry allows for quick penetration into the concrete. No hole cleaning is necessary when installing in ceilings or floors or when using hollow drills with suction. The expansion pressure-free anchoring (recessed cut) ensures minimal edge and axis distances. 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 up to 20 mm twice, enabling the component to be shimmed and/or aligned.

Note: For outdoor and damp area applications, use the FBS II R version. When mounted vertically (in ceilings and floors) and using hollow drills with suction, no hole cleaning is required. For drilling into the ground, a depth of 3 times the drill diameter must be achieved.

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