A locking device (11), e.g. a lock washer, for use with a screw threaded fastener (71), said locking device comprising at least a first disc-like body (12) comprising an annular portion (13) with at least one aperture (15) therein and a central through-hole (14) e.g. a washer having notches (15) open to the outer periphery and at least one further body (25) held in said one aperture (15). The further body may be shim (22) also having a central hole (24) and at least one tab (25) which extends through the notch (15) and has an end portion which juts above adjacent surface of the washer to engage an adjacent surface on the fastener when compressed, on tightening of the fastener deflects within the void of the aperture in which it is located under the influence of the tightening of the engaging surface such that under any tendency to loosen, the tab jams against the opposing surfaces and resist loosening of the fastener.
A locking device for use with a screw threaded fastener, said locking device comprising at least a first disc-like body comprising an annular portion with at least one aperture therein and a central through-hole and at least one further body held in said one aperture, the further body having a least one projection extending through the one aperture and having an end portion jutting above adjacent surface of the disc-like body to engage an adjacent planar surface on the fastener when compressed on tightening of the fastener so that the projection deflects within the void of the aperture in which it is located under the influence of the tightening of the engaging surface such that under any tendency to loosen, the tab jams against the opposing surfaces and resists loosening of the fastener.
