A jam nut is a low profile type of nut, typically half as tall as a standard nut. It is commonly used as a type of locknut, where it is "jammed" up against a standard nut to lock the two in place. It is also used in situations where a standard nut would not fit.
The term "jam nut" can also refer to any nut that is used in the same function (even a regular-thickness nut used for the jamming purpose). Jam nuts, other types of locknuts, lock washers, and thread-locking fluid are ways to prevent vibration from loosening a bolted joint.
Jam nuts are also known as: half height nuts, hex thin nuts. Jam nuts are used without lock washers when jammed against another nut, and may be used with lock washers when installed as a single nut.
