To attach a nut to a plate-shaped workpiece, especially to a metal sheet, in such a way that it has self-locking properties without additional aids or parts, the force fastening the nut and acting on a free thrust surface of the nut is divided into at least two effective components generating a shearing stress in the nut material, transverse deformation of a part of the nut facing away from the workpiece being produced, and the thread diameter in the thread region deformed for self-locking purposes being reduced, while at the same time the thread pitches are inclined towards the center axis. A nut which can be used either as a locking nut or as a non-locking nut is characterized by a force-deflecting design of the thrust surface. |
