Hanger bolts are headless bolts designed to hang materials from wooden structures. One half has a lag thread wood screw and the other half has standard threading with a blunt tip. Commonly used to hang wiring and sheet metal, the assembly is complete when the lag end is wrenched into a pre-drilled hole, the item is threaded or attached, and a nut is added.
