Concrete Anchor Screw Steel 3/8" x 4"

Achieve a rock-solid hold in concrete, block, and brick with this heavy-duty steel concrete screw anchor. Engineered for both professional contractors and DIY enthusiasts, its one-piece design installs quickly with no additional hardware, delivering reliable strength where you need it most. The hex-drive head features under-head ribs to minimize stripping, while a corrosion-resistant coating ensures lasting performance—even in cracked or seismic-rated applications.

Whether you’re fastening sill plates, electrical equipment, furring strips, handrails, window framing or other fixtures, these anchors make every project faster and more secure. Simply drill the proper pilot hole with a carbide-tipped masonry bit, drive the anchor flush, and enjoy immediate holding power.
