Fischer 558239, Skrue, Rustfrit stål, Beton, Delvis gevind, Allen (hex), SW13

The powerful concrete screw for top installation comfort in external areas.
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.
- 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.
- 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 three embedment depths, allow for using the UltraCut FBS II R in many different applications and enable a high flexibility.
- The short UltraCut FBS II R, with a reduced embedment in depth, allows for a short drill hole depth, fast installation and less reinforcement hits.
- The concrete screw FBS II 6-10 in zinc-plated steel, multiple-coated steel CP and stainless steel R has an ETA for bricks of clay (EN771-1), solid sand-lime brick (EN771-2) and perforated sand-lime brick (EN771-2) for a flexible use in different substrates.
- The installation of the concrete screw FBS II 6-10 in zinc-plated steel, multiple-coated steel and stainless steel R in masonry brick can be made in the joints or in plastered substrates also in groups.

The fischer concrete screw UltraCut FBS II US R, with the specially hardened red tip is a high-performance anchoring solution for fast installation. The concrete screw with the pressed washer is ideal for applications outside or in damp areas. 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 (undercut) ensures low edge and axial spacings.

Functionality
- The UltraCut FBS II R 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).
