      Bolt anchor FBN II GS with large washer

      The fischer bolt anchor FBN II with its large washer is a steel anchor for cost-effective fixations in non-cracked concrete. With its large pre-mounted washer, the zinc-plated steel anchor is recommended for the fastening of footing beams and sills as well as for other wood constructions. 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.

      The advantages / Product description

      Advantages
      • The larger washer included with the FBN II GS creates a large supporting surface and, as such, allows for use in wood construction.
      • The pre-fitted washer ensures a fast assembly.
      • The standard anchorage depth achieves the maximum load-bearing capacities. This means that fewer fixing points and smaller anchor plates are required.
      • The anchor is also ideal for large fixture thicknesses.
      • The long thread balances component tolerances and stand-off installations, and thus increases flexibility.
      • Fewer hammer blows and the minimal torque slippage allow for a noticeably simpler assembly.
      • The drive-in pin protects the threaded screw from damage, and as such ensures a faster installation and dismantling of the fixture.

      Assembly instruction

      Functionality
      • The FBN II GS 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.
