Fixing part for theft-proof fixing of a vehicle wheel to a wheel hub comprises a thread region concentric to an axis (24) of the fixing part and designed as an external or internal thread corresponding to the counter-thread of the hub. A drive region (34) has recesses distributed in a coded arrangement, especially key holes (52), onto which a driving torque is applied. A guide region extends in the direction of the axis. The drive region has an edge region (66) which rises outward from the recesses. Preferred Features: The edge region rises at an angle (beta) between 5 and 75, especially 20 and 60degrees, relative to a radial plane. The edge region rises constantly outward, especially in a linear or curved manner.
