Zusammenfassung:	A self-piercing rivet element is provided with a body part having a thread cylinder and with a hollow rivet section to be pressed into an as yet unpierced component. In this arrangement, the rivet section is designed to be at least regionally dilatable by means of a die button and tapers in the direction of the central longitudinal axis and away from the body part. The hollow rivet section has, inthe region of the transition to the body part, a diameter, which is larger than the outer diameter of the thread cylinder. Furthermore, the rivet section has a closed peripheral wall and an opening at its free end which corresponds at least substantially in diameter to the core diameter of the thread cylinder. Furthermore a component assembly, a method for the manufacture of the component assembly and the die button are claimed.
