Abstract
A component assembly comprises a sheet metal and a fastener element. A flange has a larger diameter and a shaft of smaller diameter extends away from the flange and merges at its end remote from the flange into a cylindrical rivet section. The fastener element is used with sheet metals with thicknesses in the range of 3 mm and larger. With thin sheet metal parts the sheet metal has a smooth pierced cylindrical opening with a diameter corresponding to the diameter of the shaft. The cylindrical rivet section is reshaped to a rivet bead contacting the sheet metal underside. Medium thickness sheet metal parts have a stepped hole with the hole region of larger diameter receiving the rivet bead. For thick sheet metal parts the sheet metal has a conical pierced hole and the cylindrical rivet section is reshaped to a conical rivet bead wedged in the conically diverging hole.
