Abstract
A method for the connection of sheet parts, of which at least one is formed as an organic sheet part, with the aid of an auxiliary joining part and an apertured metal washer, the auxiliary joining part having a functional section with an undercut and a piercing section with a shaft surface and a shaft recess. The sheet parts and the metal washer are brought into a stacked arrangement in such a way that the metal washer contacts the organic sheet part. The piercing section slugs are punched out of the stacked sheet parts. The auxiliary joining part is joined to the metal washer. The other of the undercut or of the shaft recess is brought into a holding engagement with a sheet part not formed as an organic sheet metal part or with a further metal washer.
