Jam Nut, 1 in-14 Dia

Hex jam nuts are thinner than a standard hex nut, but have the same dimension across the flats and corners. 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. Warren Fastener’s #14825 nut measures 1 in-14, and is made of zinc.
