Hanger Bolts
Hanger bolts are a type of headless fastener with a lag screw thread on one end for wooden components, and a machine screw (unified) thread at the other end for use with nuts. The end of the lag screw thread specifically is designed as a taper, meaning the threading continues to the blunt tip of the bolt. Depending on the length of both types of thread, some sizes offer full or partial threading.
