Everbilt 5/16 in. - 18 in. x 3-1/2 in. Stainless Hanger Bolt

These hanger bolts are headless bolts designed to hang materials from wooden structures, walls or overhead. One half has a lag thread wood screw with a pointed tip, and the other half has standard machine thread with a blunt tip. Commonly used to hang wiring and ceiling hooks, the assembly is complete when the lag end is screwed into a pre-drilled hole. The item is threaded or attach on the opposing end and a nut is added. Stainless steel offers excellent corrosion protection.
