Abstract: A method for placing a functional element, especially a fastening element, in an especially liquid-tight and/or gastight manner, on a metal part. In this method a functional element provided with a hollow head segment is pressed against the metal part (212) witch is supported by a die (214).

The parts (216) are kept in a stationary position during the forming process but are partially removed from the die to enable the functional element which is placed on the metal part (212) to be extracted. The invention also relates to a die, a functional element, an assembly element and a die arrangement.
