ABSTRACT:
An improved lock nut of the kind having a deformable section at one end, with a generally elliptical cross-section. The deformable section has a maximum radial thickness in the region of the ellipse's minor axis, to provide a desired degree of frictional locking when threaded onto a bolt, and it has a minimum radial thickness in the region of the ellipse's major axis, to reduce stresses and plastic deformation that could otherwise adversely affect the lock nut's reusability.
