<p>The invention relates to a screw device, an assembly for theft-proofing vehicle wheels, and a motor vehicle with theft-proofed vehicle wheels. The screw device (1) comprises a screw (2) having a head (5) and a threaded portion (6) intended to be screwed into a thread (7) of a wheel hub (8), a sleeve (3) and a lock member (4), wherein the threaded portion (6) is intended to be screwed into the thread (7) of the wheel hub (8) via a recess (14) arranged in a central portion of a vehicle wheel (13). The lock member (4) comprises an endless, smoothly undulating or curved lock member (9). The dimensions of the sleeve (3) are adapted to the dimensions of the recess (14), so that regions of the central portion adjacent to the recess (14) substantially entirely and with close fitting will encompass a circumference (15) of the sleeve (3) when the threaded portion (6) has been screwed into the thread (7). The invention can be applied to all types of vehicle wheels, and particularly advantageously when exclusive private cars with special rims are concerned.</p> |
