Patent ID: 8382601

Claim:
A method for producing fastenings or fasteners having radial outer contours from a solid metal, which comprises the steps of: forming, in a first pressing stage, at least three recesses at a fixed radial distance in a prefabricated blank having at least one shank-shaped section; performing a second pressing stage, by the steps of: inserting the prefabricated blank with the recesses in a multi-part split mold with at least three die stocks in such a manner that the recesses are at places where the die stocks are open, in an open, starting position, the die stocks having an inner profile that forms an outer contour on the prefabricated blank; and performing a pressing process by closing the die stocks, by means of an application of a radial force, at least one radial outer contour is pressed into the shank-shaped section of the prefabricated blank resulting in a completed blank, and no radial outer contour is created during the pressing process in a region of the recesses extending in an axial direction, and that an entry of material between the die stocks of the multi-part split mold is prevented during the pressing process by means of the recesses running in the axial direction.
