      Top Features
      • With assessment document (ETA) the hot dipped galvanised steel version is covered for external use with variable working life depending on environment and corrosion conditions.
      • 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.
      • Simple assembly due to few taps and minimal slippage.

      The advantages / Product description

      The cost-efficient fixing made of hot-dip galvanised steel for use in non-cracked concrete.
      Advantages
      • The standard anchorage depth achieves the maximum load-bearing capacities. This means that 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 first bolt anchor with variable working life covers the usage of bolt anchors in wet conditions and outdoor areas.
      • 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.
      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.

      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.
