Single Expansion Shields are a corrosion resistant anchor that is designed to be used with a machine bolt in concrete, brick, block, and stone. The anchor comes pre-assembled and consists of a zamac alloy anchor body and an expansion cone. The expansion cone is drawn into the anchor body as the machine bolt is tightened into the anchor. The anchor will retain its holding power even if the mating bolt is removed and replaced.
