In order to optimize a nut and a method for the production of a nut, comprising a nut body which is provided or can be provided with an internal thread and has a polygonal section with a polygonal outer contour which has, on the one hand, edge areas and, on the other hand, key faces which are located between the edge areas and extend in key face planes extending in a manner conforming to standards, in such a manner that it has mechanical properties which are as ideal as possible with as low a weight as possible, it is suggested that the nut body have a plurality of recesses which extend into the nut body in the direction of the bore proceeding from the respective key face planes.

A securing nut and a screw-nut blank for producing the securing nut are disclosed. The securing nut (20) has a shaped collar (8) on an end surface (3), in one piece with the nut body (1), and an inner end surface (11) running concentrically relative to an internally threaded bore (9) of the nut body (1). Nut (20) is spaced axially (A) from the internally threaded bore (9) and has a securing internal thread (22) offset relative to an internal thread (23) of the internally threaded bore (9). The screw-nut blank (10) has an axially running annular collar (2) to form the shaped collar (8), and has a contour which remains constant in the circumferential direction. In the axial direction (A), the annular collar (2) has a cross-sectional shape which increases as the distance from the end surface (3) increases, in particular a conical cross-sectional shape. The ratio of a thickness (S1) of the annular collar (2) in the transition portion (6) with respect to the end surface (3) to a thickness (S2) of the annular collar (2) at a free end (7), which is used to form the inner end surface (11), is between 0.45 and 0.75, preferably between 0.5 and 0.7.

Self-locking nipple for attaching wheel spoke to wheel part. The self-locking function of the nipple is created by deforming the nipple body in a rotationally symmetrical way and over a predetermined axial distance, such that such a narrowed part is created in the internal screw-thread of the nipple which is rotationally symmetric with respect to the longitudinal axis of the nipple and extends over only one to two windings of the internal screw-thread.
