FISCHER UltraCut FBS II 10 x 100 US – concrete screw with integrated washer, 3 embedments 45/35/15 mm, fast installation, ETA, pack of 50
0
Description
The FISCHER UltraCut FBS II 10 x 100 US is a high-performance concrete screw with a specially hardened red tip and the US version featuring an integrated washer. Three possible embedment depths (45 / 35 / 15 mm) let you use one screw for different fixture thicknesses, while the serrated thread geometry bites quickly into concrete for fast installation. It holds an ETA for cracked and non-cracked concrete and allows two re-tightenings for position correction.
Benefits and unique features
- Three embedment depths (45 / 35 / 15 mm) – one screw for many tasks.
- Serrated thread & hardened tip – fast cutting into concrete, time-saving.
- ETA – use in cracked and non-cracked concrete, including seismic C1/C2.
- Two permitted re-tightenings for adjustment and re-clamping.
- US version with integrated washer – ideal for slotted holes and timber connections.
- No hole cleaning required for overhead/floor installation; in floors, drill ≥3×Ø deeper.
Properties and applications
- Applications: balustrades, brackets/anchor plates, steel profiles, racking systems, safety barriers, thresholds and beams, temporary site fixings, formwork props.
- Base materials: concrete C20/25–C50/60 (cracked & non-cracked); also suitable for C12/15 and dense solid masonry.
- Installation: through-fixing; use an impact driver with the proper bit.
