The fischer bolt anchor EXA is a particularly installation-friendly steel anchor for anchorings in non-cracked concrete. In the zinc-plated steel design, the bolt anchor is suitable for the anchoring of railings, cantilevers, and cable trays inside. The two expansion clips increase the expansion range and reduce the torque slippage. This saves time during the installation process. The drive-in pin protects the threaded screw from damage, and as such ensures a faster installation and dismantling of the fixture.
