Zinc Nail Drive Anchor Nylon Truss Hammer in Masonry Concrete Anchors

Hammer Drive Anchors, sometimes referred to as nail or pin drive anchors, consist of an expander drive pin and an expansion sleeve. Once the anchor is placed into a pre-drilled hole, the nail or "pin" is hammered into the anchor causing it to expand and wedge itself into the concrete or masonry forming a tight fit.
