Abstract:
1. A screw nut comprising a metallic material with a threaded bore and an inner groove which is associated with the longitudinal axis of said threaded bore in radially circumferential fashion, wherein an annular collar is integrally formed on one of the end faces of the screw nut and is bent cross-sectionally towards the axis in such a way that, with a section of this end face which surrounds the threaded bore as a bearing face, it delimits an accommodating slot which is directly associated therewith, the cross-sectionally deformed annular collar forms a shaped collar, whose outer face runs at a radial distance from the axially parallel edges of the wall face sections of the screw nut, the accommodating slot being arranged close to the outer face of the shaped collar, the accommodating slot, which provides two parallel peripheral edges, is inclined cross-sectionally at an angle with respect to the peripheral edges, and wherein the annular collar is bent cross-sectionally towards the longitudinal axis in such a way that the accommodating slot is closed towards the threaded bore and the peripheral edges of the accommodating slot bear against one another towards the threaded bore.
