Abstract
A fastening element (1) such as a tensioning nut made of deep drawn steel sheet and having a threaded section (5) formed therein by rolling and on its outer peripheral surface (6), the fastening element comprises an integrally formed dog device (9) which starts from the end of the fastening element on which the threaded section (5) is arranged and comprises at least one tab-like section (7) which is bent over onto the outer peripheral surface (6) of the fastening element (1) which when viewed in axial direction, the tab-like section (7) may overlap the threaded section (5) at least partly, economic to manufacture and fulfills the requirements of light-weight construction and a particular advantage of the invention is that the dog device (9) has no influence on the threaded section (1).
