Fischer FBS II concrete screw 8 mm diameter steel 00536851

Advantages:

• UltraCut FBS II 8-14 US with hex head feature the already integrated washer
• Up to three certified screwing depths for maximum flexibility in the load and thickness of the object being fastened
• Special sawtooth geometry allows rapid threading in concrete
• No hole cleaning required for ceiling installation, floor installation by drilling a hole 3 times deeper than diameter or using hollow drills with suction
• Anchoring does not cause stresses in the support material (undercut operation), ensuring the smallest possible spacing and edge distances
• ETA certification allows applications in cracked and non-cracked concrete and for seismic performance categories C1 and C2
• ETA certification allows the application to be adjusted 2 times by loosening the concrete screw (max 20 mm) to insert a shim (max 10 mm) and/or align the base plate
  
   

Mounting:

• When installation is ceiling or floor, no hole cleaning is required. For floor holes, the installer must drill a hole 3 times deeper than the diameter
• For optimal installation, the use of a suitable impact screwdriver with hex or Torx inserts suitable for applying tangential pulses is recommended
• The screw is properly installed when the screw head rests on the object to be fastened (visual adjustment check)
• For temporary fixings, reuse is allowed only if the concrete screw does not pass through the FUP control cylinder
• For applications in seismic performance category C2, fill the annular space between the screw shank and the hole of the object to be fixed with FIS V, FIS EM Plus, FIS HB or FIS SB resin, using the FFD Seismic Kit. The thickness of the FFD disk should be added to the thickness of the plate to be fastened when calculating the actual insertion depth of the screw into the concrete
• For applications of FBS II US screws as a shear connector, the use of the SC-ST laying tool is recommended.
