Concrete screw ULTRACUT FBS II SK

The high-performance concrete screw for absolute installation ease

The fischer concrete screw ULTRACUT FBS II SK is a powerful anchoring solution with top installation comfort. The version with the countersunk head enables use for visually demanding anchorings. The European Technical Approval for cracked concrete and non-cracked concrete as well as for seismic loads and classification into fire resistance class R 120 guarantee even more safety. The saw tooth geometry enables a quick and easy installation. No drill hole cleaning is required for installation in ceilings and floors. The expansion-free anchorage system enables low edge and axial spacings.

Product Description

Advantages

With up to 3 embedment depths, the ULTRACUT FBS II US allows for the same screw to be used for different component thicknesses.
The special saw tooth geometry enables fast cutting into the concrete.
Drill holes do not need to be cleaned during vertical installation (ceiling and floor). For floor fixings the hole must be drilled 3x drill hole diameter deeper.
Expansion-free anchoring (undercut) allows for lowest edge- and axial spacings.
The ETA approval covers applications in cracked concrete and seismic power categories C1 and C2.
The approved adjustment for the concrete screws allows the screw to be unscrewed twice to place maximum 10 mm packing below the base plate head or to align the attached part, and then to tighten the screw again.
The checking gauge allows for reuse in temporary fixings (e.g. inclined supports) covered by the national approval.

Assembly Instruction

Functionality

The ULTRACUT FBS II is recommended for the push-through installation.
Drill holes do not need to be cleaned during vertical installation (ceiling and floor). For floor fixings the hole must be drilled 3x drill hole diameter deeper.
We recommend using a tangential impact screwdriver with a suitable impact screwdriver socket or an internal TX drive.
The screw is installed correctly when the screw head sits flush on the fixture and cannot be screwed in deeper (visual setting control).
