Fischer Concrete Screw ULTRACUT FBS II 8 x 90 40/25 US hexagon with U-ring internal TX drive 536854 50 pieces
The strong concrete screw for optimal installation comfort. The fischer FBS II is the concrete screw for optimal installation comfort. The special tooth geometry enables quick driving into concrete. When mounting in a ceiling or floor, the drill hole does not need to be cleaned. Thanks to national approval, multiple uses for temporary anchorages, e.g. during formwork, are no problem. For mounting the wall bolt, a tangential impact driver with a bit suitable for the impact driver or a special TX bit is recommended. The concrete screw can be used excellently, for example, for fastening railings, crash barriers, consoles, or formwork.
Advantages
- High degree of flexibility regarding load and thickness of the mounting pieces due to up to two approved screw-in depths.
- The special tooth geometry enables rapid screwing into concrete.
- The drill holes do not need to be cleaned when mounting in ceilings or floors, or when using hollow drills with dust extraction.
- The expansion-pressure-free anchoring (back-cutting) allows for small edge and axial distances.
- The ETA approval covers application in cracked concrete as well as seismic performance categories C1 and C2.
- The approval-compliant adjustment allows the concrete screw to be loosened twice, positioned slightly below the mounting piece, and/or aligned.
- The national approval regulates multiple use for temporary anchorages, (e.g. during formwork).
Characteristic properties
- Allen bolt with hexagonal head.
- Quick insertion due to special tooth geometry.
- Approved for multiple use in temporary anchorages.
- ETA approval for cracked concrete: Maximum safety.
- When mounting in ceilings or floors, the drill hole does not need to be cleaned.
