Hex Jam Nuts

A six-sided internally threaded fastener which is thinner than the thickness of a finished hex nut.

Used in combination with a finished hex nut to keep the nut from loosening.

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.

All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc...
