2122631 9309355 PCTABS00022 A fastener bearing assembly (10) for reducing the turning friction between a head of a fastener (12) and an object to be fastened, for example, a vehicle wheel. The assembly (10) comprises a first part (14) having a first pressure transmitting surface (16), and a second part (18) having a second pressure transmitting surface (20), and adapted to rotatably receive the first pressure transmitting surface (16) in facing relation thereto. A solid dry lubricant material in the form of an annulus (22) is provided to reduce friction between the first and second pressure transmitting surfaces (16, 20). In use, the first part (14) rotates with the head of the fastener (12) and the second part (18) remains stationary relative to the surface (23) of the fastened object so that the dry lubricant annulus (22) acts as a bearing between the head of the fastener and the fastened object. A locking member (40) adapted to engage a surface of both the first and second parts (14, 18) may be provided to prevent rotation of the first and second parts relative to one another.
