Locknut

A locknut, also known as a lock nut, locking nut, prevailing torque nut,[1] stiff nut[1] or elastic stop nut,[2] is a nut that resists loosening under vibrations and torque. Elastic stop nuts and prevailing torque nuts are of the particular type where some portion of the nut deforms elastically to provide a locking action.[2] The first type used fiber instead of nylon and was invented in 1931.
