Self locking nuts work by using increased friction between the threads of the two mating faces to cause a slight distortion of the threads. They are frequently used in areas where vibration is experienced.

Self locking nuts can be re-used, but only a few times before they lose their inherent locking qualities.

Stiff nuts, jam nuts and bent beam nuts are all terms that are used to describe self-locking nuts.

UNC stands for Unified National Coarse. It is a common imperial thread type with less threads per axial distance than its UNF equivalent.

Unified thread types (UNF and UNC) were introduced at the beginning of World War 2 to enable the interchangeability of machinery manufacturing between the USA, Canada and Great Britain. Still commonly found on a vast array of old machines and vehicles in the UK, UNF and UNC threads continue to be the standard thread in the USA and Canada.
