Two metal sheets are connected to each other by the use of a self-piercing rivet.
When using self-piercing rivets, the metal on the die side is pressed into an indentation of the rivet. With semi-tubular rivets, a sharp collar on the rivet is pressed through the first metal sheet into the sheet on the die side and simultaneously extended outward. The result is a permanent joint of metal parts which may have different wall thicknesses or consist of different materials. For the setting process, the joint position must be accessible from both sides. A pre-drill in the component is not necessary.
