DEWALT 1/2X4 WEDGE-BOLT(316SS BIMETL) (Box of 50)

The 1/2X4 WEDGE-BOLT(316SS BIMETL) is a self-tapping concrete screw anchor that threads directly into a pre-drilled hole in concrete or block, with no separate anchor body or expansion clip required. Made from marine-grade 316 stainless steel, it installs fast and can be removed if needed, making it a favorite for contractors hanging conduit, shelving, and fixtures, and simple enough for a first-time DIYer with a hammer drill.
