Externally threaded self-locking nut

摘要

A self-locking, externally threaded locking nut the outer periphery of the nut adjacent the threaded portion thereof having an annular groove in which is positioned an elastic ring. Portions of the outer periphery of the elastic ring are deflected outwardly by the nut to form protuberances for effecting increased frictional resistance to turning between the locking nut and a threaded cylindrical body to produce a locking action.
