The fischer sleeve anchor FSA is a zinc-plated steel anchor with a hex socket or with a bolt head with a nut and washer for structural anchorings. The optimised anchor geometry offers a high shear load resistance and a high level of safety for structural anchorings. The FSA is installed in a time-saving push-through installation. During tightening, the cone is pulled into the expansion sleeve and expands it against the drill hole wall. The recesses act as a crumple zone to take the torque slippage. In this way, the fixture is pulled onto the base material.
