DEWALT Screw-Bolt+ Hex Head Mechanically Galvanized, 5/8" x 8" (Box of 25)

The Screwbolt MG 5/8IN X 8IN 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 zinc-plated carbon 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.
