Abstract
A retaining nut comprises a nut body and a plurality of axially extending integrally formed deflectable locking fingers. The locking fingers have a frusto-conical surface opposite a threaded surface. The frusto-conical surface of the locking fingers are adapted to co-operate with a conical washer. Tightening the threaded nut on a threaded shaft against the washer causes the locking fingers to deflect radially towards the shaft. This provides a secure radial clamping of the nut on the shaft.

A retaining nut comprising a nut body and a plurality of axially extending integrally formed deflectable locking fingers, wherein the locking fingers have a frusto-conical surface opposite a threaded surface.
A retaining nut and washer combination comprising a retaining nut in accordance with any preceding claim, and a conical washer, wherein the frusto-conical surface of the nut locking fingers and a frusto-conical surface of the conical washer are co-operating plane contact surfaces.
A method of retaining a nut on a threaded shaft, the method comprising:
- providing a retaining nut comprising a nut body and a plurality of axially extending integrally formed deflectable locking fingers, the locking fingers having a frusto-conical surface opposite a threaded surface;
- providing a conical washer;
- and
- threading the nut onto a threaded shaft such that frusto-conical surfaces of the washer and the locking fingers co-operate to deflect the locking fingers radially towards the shaft.
