Abstract

A locking nut includes a threaded main bore for receiving a threaded portion and a number of oblique bores in each of which is positioned a locking pin having a forward end for engagement against the threaded portion. The oblique bore and the associated locking pin have a common longitudinal axis extending at generally the same angle to the axis of the threaded main bore as one of the flanks of the thread of the threaded main bore so that the forward end of the locking nut has at least one flank generally parallel to the longitudinal axis and lying parallel to the portions of the one flank of the threaded main bore adjacent the inner end of the oblique bore. Each locking nut is generally cylindrical and possesses an outer surface that is grooved or serrated to facilitate insertion of the locking nut into the respective oblique bore.
