ABSTRACT:
Bolt element (10) having a shaft part (12) which is designed at a first end (14) for a rivet connection (16) to a panel element (18), in particular to a sheet metal part, is characterized in that the shaft part (12) has a spherical formation (22) at its other end (20) the ball diameter (D) of which is larger than that of the shaft part (12). In this manner a bolt element with a spherical head can be manufactured in an extremely favorable manner price-wise and it can be ensured that the spherical head has no burr which would lead to the wearing of the socket provided in operation which slides on the spherical head.
