3/8'' x 4'' Hex Head Concrete Screw Bolt

The Mega-Bolt anchor is a heavy-duty, single-piece screw bolt that is quick to install, fully removable, and easily identifiable. The unique thread design allows it to be installed with minimal torque and enhances job site productivity. It also eliminates the need for multiple tools and accessories. Simply attach the appropriate socket driver to any powered impact wrench or torque wrench and fasten. Steel threads along the anchor shaft tap quickly into the hole during installation to provide deep thread engagement and efficiently transfer the load into the base material. The reverse serrated teeth on the underside of the hex washer head help to secure the load against the fixture and prevent over-torquing.
