The device has a threaded bolt (1) matched with an internal thread of a threaded portion (3) of a wheel hub of a motor car, where a rim is overlapped with the internal thread. A supporting element is mounted on the threaded bolt for supporting pressing forces at the rim. The supporting element comprises an expanding element (5). Diameter of the expanding element is adjustable between a value that is smaller than a value of diameter of a through-hole of the rim and a value that is larger than the diameter of the through-hole. |
