Abstract: A wheel nut assembly for fixing a wheel to a vehicle hub. The wheel nut assembly has a wheel nut. The wheel nut has an internal thread. The wheel nut assembly further includes a wheel stud having an external thread adapted to co-operate with the internal thread of the wheel nut. The wheel stud further has an internal thread. A retaining member has an external thread of an opposite hand with respect to the internal thread of the wheel stud for cooperating with the internal thread of the wheel stud. A locking member is adapted to engage both the retaining member and the wheel nut to prevent relative movement there between and is further adapted to permit a location of the retaining member to be visually identified when the locking member is engaged to both the retaining member and the wheel nut.

Abstract: A wheel nut assembly is disclosed in which a wheel stud (1) is provided which comprises a first portion having a first external thread (3) adapted to cooperate with an internal thread on a wheel nut (4), and a second threaded portion (5) having a thread (6) of the opposite hand to the first external thread (3) which cooperates with a retaining member (9) having a thread (10) which is of the same hand as the second threaded portion. The retaining member (9) may be a bolt which engages a threaded bore provided in the end of a standard stud. A locking cap (12) may be provided which fits over the wheel nut (4) and the bolt (9) to prevent relative rotation between the two. This has the advantage of preventing the wheel nuts becoming loose on the wheel.
