The high-performance concrete screw for easy installation.
The ULTRACUT FBS II A4 is designed for push-through installation. The specially hardened red tip provides a faster and more secure installation. It is recommended to use an impact wrench with a suitable impact socket or torx bit. Drill holes do not need to be cleaned during vertical installation (ceiling and floor) or when using a hollow drill. For floor fixing the hole must be drilled 3 x Ø deeper. The ETA approval covers applications in cracked concrete, as well as seismic performance categories C1 and C2. The concrete screw ULTRACUT FBS II A4 offers the possibility for usage in masonry (solid building material).
