fischer ULTRACUT FBS II 8 x 130 80/65 US TX

The high-performance concrete screw for absolute installation ease.

Art.-No. 536857
Top Features
  • With up to 3 embedment depths, it allows for the same screw to be used for different component thicknesses.
  • The special saw tooth geometry enables fast cutting into the concrete.
  • The approved adjustment for the concrete screws allows the screw to be unscrewed twice to align the attached part, and then to tighten the screw again.

Product Description

The fischer ULTRACUT FBS II is the perfect concrete screw for top installation comfort. The special saw tooth geometry enables fast cutting into the concrete. Drill hole cleaning is not required for installations in ceilings or floors. Thanks to the national approval, multiple usage for temporary anchorings (for example, formwork construction) is permitted. For the installation of the wall screw, we recommend a tangential impact driver with a compatible socket or a special TORX bit. The concrete screw is ideal for the fixation of railings, protection barriers, cantilevers, and formwork bracings, for example.
  • Maximum flexibility with regard to load and fixture thickness due to up to two approved embedment depths.
  • The special saw tooth geometry enables fast cutting into the concrete.
  • No drill hole cleaning is required for installation in ceilings or floors, or use of hollow drills with suction.
  • The expansion-free anchorage (undercut) ensures really low edge and axial clearances.
  • The ETA approval covers applications in cracked concrete and seismic power categories C1 and C2.
  • Approval-compliant adjustment allows the concrete screw to be undone twice and the fixture to be underlaid or adjusted.
  • The national approval allows multiple usage for temporary anchorings (for example, formwork construction).

Assembly Instruction

  • 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 torx drive.
  • The screw is installed correctly when the screw head sits flush on the fixture and cannot be screwed in deeper (visual setting control).
