    Patent number: 11686336
    Abstract: A semi-hollow punch rivet by which a joint is establishable. The rivet includes: a rivet head having a rivet shaft, which comprises a lateral surface, a rivet foot having a foot front surface is provided at an end of the rivet shaft facing away from the rivet head, the foot front surface is perpendicular to a longitudinal axis LA of the rivet shaft, and a bell-like shaft cavity extends into the rivet shaft beginning at the end facing away from the head. The shaft cavity is formed by: an inlet portion beginning at a radial inner side of the foot front surface and extending arc-shaped with an inlet radius RS in the direction of the rivet head, a linearly extending continuation portion into which the inlet portion transitions tangentially and which is arranged in an acute angle with respect to the lateral surface, and a final dome portion.
