Hanger bolts have threaded areas at both ends: a lag screw thread at one end and machine screw thread on the other. They are used to suspend objects from or attach items to wood. Like a typical stud, they are headless, double-ended bolts that have threads at each end—lag threads to screw into wood but, at the other end, machine screw threads to accept a nut or thread into an internally threaded (tapped) hole.
