ANCHOR - DOUBLE EXPANSION 1/4" (100)

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, 2 expansion cones (1 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. Recommended for anchoring into base materials of questionable strength.
