Zusammenfassung:	A fastening bolt has a threaded screw (11) with a terminal portion (18) whose diameter (19) is less than that of the threaded portion, and an end surface (21) of said terminal portion has a transverse opening groove (22). The fastening bolt also has a nut (30) comprising a threaded body (32) and an unthreaded crown (34) drilled with at least two holes (35) diametrically opposite to one another and a rod (23), able to fit in the groove of the screw and in the two lateral holes of the nut to lock the bolt. The body of the nut comprises a driving portion (38), as well as a cylindrical portion (39) less thick than the driving portion, and the cylindrical portion (39) of the nut has an elliptical deformation that was previously a circular shape.
