Abstract

A method of producing fastening elements and which includes placing, in a pin guide of a setting tool, an element having a first, tip-carrying stem section and a second stem section having a hardness lower than that of the first stem section, and forming during a setting process effected by a piston (21) of the setting tool, with the piston, a head (16,161) at a free end (15) of the second stem section (13) of the element (10) and having a diameter (17) greater than a diameter (18) of the second stem section, so that a fastening element (19,191) is produced, a fastening element produced by the method; and a setting tool for driving a fastening element formed in accordance with the method.
