Abstract
In order to further develop a blind rivet element (5) comprising a head (51), an adjoining hollow shaft (53), the outer side of which has an outer diameter smaller than the head (51), and an internal thread (54) provided inside the shaft (53) and having an axial separation from the head (51), in such a way that when installed the blind rivet element (5) always forms a controlled deformation, in particular in the form of a bulge, at the same specifiable location, it is proposed that the shaft (53) is provided with a radially outwardly protruding adjustment contour (55) in the region of the head (51), that the shaft (53) has a curvature (57) formed in the radial direction and that said curvature (57) is arranged between the adjustment contour (55) and the internal thread (54).

A blind rivet element comprising:
- a head;
- an adjoining hollow shaft, the outer side of which has an outer diameter smaller than the head;
- and
- an internal thread provided inside the shaft and having an axial separation from the head;
- characterized in that
- the shaft is provided with a radially outwardly protruding adjustment contour in the region of the head, the adjustment contour being a centering element,
- the shaft has a curvature formed in the radial direction,
- the curvature is arranged between the adjustment contour and the internal thread,
- the curvature extends in a circumferential direction and is rotationally symmetric at any rotational turn, and
- the curvature is a fully closed bulge.
