It contains a wedge shaped nut at one end and a wedge shaped hollow cone at the other end. Integral lugs on the nut and cone keep the wedges from turning in the tubular shield during expansion. The anchor are of precision diecast zinc alloy commonly known as Zamak 3.The expansion action at one end of the anchor distributes the anchored load throughout the length of the anchor. This expansion anchor is recommended for shear loads or where the bolt is subjected to side pressure or vibration. Once fastened, the object may be unbolted, removed, and/or refastened.
