Product description

The cost-efficient fixing made of stainless steel for use in non-cracked concrete.

The fischer bolt anchor FBN II is a steel anchor for cost-effective fixings in non-cracked concrete. Due to the long thread and the two anchorage depths, the fischer bolt anchor FBN II can be used in a particularly flexible manner. The bolt anchor is also suitable for stand-off installation as well as pre-positioned and in push-through installation. The stainless steel version of the bolt anchor is suitable for fixing façade sub-structures, consoles, and ladders in external areas.

  • The FBN II achieves maximum load-bearing capacity with standard anchorage depth. This means: fewer fixing points and smaller anchor plates
  • If the reduced anchorage depth is used, then this lowers the drill hole depth and simplifies installation
  • Component tolerances are balanced out with the long thread. In addition, FBN II is also suitable for stand-off installations. This increases flexibility
  • Stainless steel: permanent safety in outdoor use
  • Ideal for high loads
  • The standard anchorage depth achieves the maximum load-bearing capacities. Thus fewer fixing points and smaller anchor plates are required
  • The reduced anchorage depth reduces the drill hole depth. This minimises the amount of time needed for installation whilst increasing flexibility
  • The long thread balances component tolerances and allows for stand-off installations, thus increasing flexibility
  • Few hammer blows and the minimal torque slippage allow for a noticeably simpler installation
  • The drive-in pin protects the thread from damage, and thus ensures a faster installation and dismantling of the attachment

Suitable for

  • The FBN II is suitable for pre-positioned and push-through installation; also suitable for stand-off installation under certain conditions
  • Prior to installation, place the hexagon nut in the optimal position (the drive-in pin projects by approx. 3 mm out of the hexagon nut)
  • When applying the torque, the cone bolt is pulled into the expansion clip and expands it against the drill hole wall
  • The head embossing offers a simple control of the anchoring
  • In the case of series installation, we recommend using the FABS bolt anchor setting tool
