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 self-leveling support includes a first stile (1) and a second stile (2), a first leg member (6) and a second leg member (7), each having an elongate element adapted to move longitudinally relative to one of the stiles (1, 2), a spacer (3) adapted to secure the stiles (1, 2) substantially parallel to each other, and a cross member (8) adapted to pivot about a pivot pin (9) acting in a guide (10) in the spacer (3) substantially midway between the stiles (1, 2), the cross member being connected at each end to a respective portion of the leg members, angular movement of the cross member about or with the pivot pin causing one leg member to move outwards relative to its respective stile while the other leg member moves inwards relative to its respective stile.

Abstract: A wheel nut assembly is disclosed comprising a wheel stud (1) having a first portion having a firs external thread (2) which is adapted to co-operate with an internal thread provided on a wheel nut (3) and a second portion (4) having a thread (5) of the opposite hand to the first external thread which co-operate with a retaining member (6) having a thread which is of the same hand as the second threaded member, and a locking member (8) which is adapted to engage both the retaining member, and a locking member (8) which is adapted to engage both the retaining member (6) and the wheel nut (3) to prevent relative movement therebetween, and in which the locking member (8) is so constructed and arranged to permit the location of the retaining member to be visually identified whilst the locking member is in place. Preferable, the locking member comprises a cap that may completely or partially cover the wheel nut and the retaining member.
