A wheel fastening system 100 for a vehicle comprises a hub 108 on which a wheel (102 figure 1) is mountable, the hub comprising a threaded surface 116, and a nut 106 which is engageable with the threaded surface to fasten the wheel to the hub, wherein, when the nut is engaged with the threaded surface, rotation of the nut in a first direction about an axis of the hub results in tightening of the nut on the hub. The system further comprises a pawl assembly 130 arranged on a first one of the hub and the nut, the pawl assembly comprising one or more pawls 132a,d, and a ratchet 128 arranged on a second one of the hub and the nut. When the nut is engaged with the threaded surface, each of the one or more pawls is configured to engage with the ratchet to thereby allow rotation of the nut about the axis in the first direction and block rotation of the nut about the axis in a second, opposite direction. In this manner, unwanted loosening of the nut, such as a centrelock nut, on the hub may be prevented.
