The fischer high-performance anchor FH II B with threaded bolt is a sleeve anchor made of zinc-plated steel. The anchor is set in the time-saving through-type installation. When tightening the anchor, the cone is pulled into the expansion sleeve and expands it against the hole wall. The black plastic ring prevents the anchor from rotating and absorbs the torque slippage. This means that the fixture is pulled towards the anchoring base. The fischer high-performance anchor FH II B with threaded bolt is ideally suited to fix railings, steel constructions, and cable trays in cracked and non-cracked concrete.
