A Jam nut is similar to hex nut but typically half as tall as a standard Hex nut.It is also used in installations where a standard hex nut would not fit.Hex jam nuts have two common applications. A jam nut can be threaded onto a bolt and run tight against the standard nut which will lock the nut in place and prevent it from backing off. Jam nuts are sometimes used for leveling purposes as well.
