摘要：
A bolt with braked unscrewing consists of a screw and a nut. The screw or nut includes, in the axial direction, at least three stepped portions of continuous thread, namely an introduction portion for introducing the screw into the nut, a braking portion and an intermediate portion connecting the introduction portion to the braking portion. The braking portion has a thread diameter that is constant and different from the thread diameter of the introduction portion.
