FLANGE NUTS. Flange nuts are hex nuts with a bottom circular flange that is larger than their top hex section. There are two types commonly available: flange lock nuts, which are prevailing torque type lock nuts, and serrated flange nuts, which are free spinning but have a serrated bearing surface to grip the mating surface.

Stainless Steel Double Threaded End Machine And Wood Hangle Bolt

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.
