Top Features

Specially hardened red tip ensures noticeably faster and safer installation
Stainless steel design ensures a very high level of corrosion protection and therefore enables use in damp rooms and outdoors
ETA assessment Option 1 and Part 6 regulates the use in cracked and non-cracked concrete for the highest safety requirements

The high-performance concrete screw for absolute installation ease in external applications.

Advantages

The specially hardened red tip provides a faster and more secure installation.
The stainless steel concrete screw guarantees a high level of corrosion resistance especially for wet rooms and external applications.
Thanks to the special saw-tooth geometry, the thread flanks cut deep into the concrete and enable higher tensile and shear forces.
Both the ETA assessment Option 1 and Part 6 regulate the use in cracked and non-cracked concrete for the highest safety requirements.
The FBS II 6 R is approved for multiple use of non-load-bearing systems and guarantees the highest safety standards during installation.
The approved product for seismic performance category C1 allows use in earthquake zones and increases the flexibility of the fields of application.
The approved adjustment for the concrete screws allows the screw to be unscrewed twice for a total of 20 mm, 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 underhead fluting prevents unintentional loosening of the concrete screw and ensures greater grip during installation and secure fastening.
The expansion-free anchorage (undercut) ensures low edge and axial spacings.

The fischer concrete screw UltraCut FBS II 6 R with the specially hardened red tip is a high-performance anchoring solution for quick installation. The concrete screw is ideal for outdoor applications or in damp areas. The European Technical Assessment for cracked and non-cracked concrete as well as for seismic loads and the fire suitability for fire resistance class R 120 guarantee additional safety. The saw-tooth geometry enables quick and energy-saving installation. The expansion-free anchorage (undercut) ensures low edge and axial spacings.

Functionality

The UltraCut FBS II 6 R is suitable for pre-positioned and push-through installation.
A tangential impact wrench with a suitable socket is recommended for installation.
No hole cleaning is required for installation in ceilings and floors or when using hollow drills. When drilling holes in the floor, drill 3 times the drill diameter deeper.
Correct installation of the screw is ensured when the screw head is in contact with the mounting part so that the screw can no longer be screwed in any further (visual setting check).
