Abstract
A fastener assembly for a wheel of a vehicle includes a screw element including a threaded portion, a first supporting surface and a number of first wedge shaped teeth being located at the supporting surface. A supporting element is rotatably connected to the screw element. The supporting element includes a second supporting surface and a number of second wedge shaped teeth being associated with the first wedge shaped teeth. The first wedge shaped teeth are located at the first supporting surface to face the supporting element and the second wedge shaped teeth are located at the second supporting surface to face the screw element. The first and second wedge shaped teeth are designed and arranged in a way to realize positive engagement between the screw element and the supporting element when the fastener assembly is being tightened and to make the first and second wedge shaped teeth slide on each other and to press the screw element and the supporting element apart when the fastener assembly is being loosened.
