Product Description

The fischer bolt anchor EXA is a particularly installation-friendly steel anchor for fixings in non-cracked concrete. The two expansion clips increase the expansion range and reduce the torque slippage. The zinc-plated steel version of the bolt anchor is suitable for fixing railings, consoles, and cable trays in internal areas.
  • The two clips increase the expansion range and reduce the torque slippage. This allows for a fast and simple installation.
  • The drive-in pin protects the threaded screw from damage, and as such ensures a faster installation and dismantling of the fixture.
  • The short version EXA K*) can be used in thinner components due to the low anchorage depth.

Assembly Instruction

  • The EXA is suitable for pre-positioned and push-through installation.
  • 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 clips and expands these against the drill hole wall.
  • In the case of series installation, we recommend using the FABS bolt anchor setting tool.
