The cost-efficient fixing for flexible use in non-cracked concrete.

Bolt anchor FBN II

The fischer bolt anchor FBN II is a steel anchor for cost-effective fixations in non-cracked concrete. Thanks to its long thread and the two anchorage depths, the fischer bolt anchor FBN II is particularly flexible. In addition to pre-positioned and push-through installation, the bolt anchor is suitable for stand-off installation. In the stainless steel design, the bolt anchor is suitable for façade sub-structures, cantilevers and ladders outside.

The advantages / Product description

Advantages
  • 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.

Assembly instruction

Functionality
  • 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.
