Finished Hex Jam Nut

Finished Hex Jam Nut

A finished hex jam nut, also known simply as a jam nut, is a type of hexagonal nut that is thinner or lower in profile compared to standard nuts. It’s designed for specific applications where space is limited or where a locking mechanism is needed. One of the primary uses of a jam nut is as a locking mechanism. It’s often tightened against a standard nut on a bolt to prevent loosening due to vibration or motion. This is particularly useful in machinery or equipment subjected to frequent movement or vibration.
