A method of attaching a functional element ( 10, 210 ), in particular a fastener element to a sheet metal part ( 12, 212 ), optionally in liquid and/or gas-tight manner, is characterized in that the functional element ( 10, 210, 410 ) is pressed against the sheet metal part ( 12, 210, 410 ) supported by a die ( 14, 114, 214, 414 ) and sheet metal material ( 13 ) is pressed by means of at least one movably mounted shaped part ( 16, 116, 216, 416 ) of the die ( 14, 114, 214, 414 ) into an undercut ( 18, 218, 418 ) of the functional element ( 10, 210, 410 ). The disclosure also claims a die, a functional element, and a component assembly comprising the functional element and a sheet metal part.
