Double Bolt Anchors

Double Bolt Anchors or Double 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, two expansion cones (one at each end of the anchor), and a wire expanding ring that holds the entire anchor together. The expansion cones are drawn in at each end of the anchor as the machine bolt is tightened into the anchor; ensuring consistent and even expansion along the entire anchor body.
