A self-locking nut for application to a threaded shaft, especially a wheel bearing nut. The shaft has a spline groove along its thread. A cup-like thrust washer fits on the shaft with a tang in the spline grove to prevent its rotation. It has retention grooves in its wall. A lock ring is slidably retained in the washer with tangs in the retention grooves. A bias spring is fitted between the washer and the lock ring. An internally threaded nut is threaded to the shaft and has a depending neck passing through the lock ring having a bearing surface to bear against the washer, and an outward deformation which prevents removal of the nut from the lock ring. |
