Hillman 1/4 In. X 1 In. Nylon Truss Hammer Drive Anchor (4-count)

Formed from engineered plastic and drive nails, the Truss Head Anchor is a fastening system that consists of two parts. It is installed by inserting the nylon shank into a pre-drilled hole and hammering the head of the nail until it meets the head of the anchor body. Driving the nail expands the split ends and allows the ribs to grip the wall of the hole. Common applications and uses include brick ties and masonry anchorage, electrical fixtures, furring strips, and aluminum frames.
