This anchor is tamper-proof and vibration-resistant one-piece anchor designed for use in concrete, grout-filled block, or masonry. The Pound-It Drive Anchor is pre-formed with a bend along the anchor shaft that creates an expansion wedge that locks the anchor in place. There is no need for secondary tightening, which speeds up and greatly reduces the cost of the anchor installation. SPIKE EQUIVALENT
