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. The inventive method is characterized in that a functional element provided with a hollow head segment is pressed against the metal part (212) witch is supported by a die (214) and the metal material is deformed into an undercut (324) by deforming the head segment when simultaneous deformation of the hollow head segment occurs and the metal part is shaped in a forming area defined by parts (216) of the die (214). Said 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 therefrom. The invention also relates to a die, a functional element, an assembly element and a die arrangement.
