<p>The element (10) i.e. bolt element, has a hollow head part (16) including external diameter that is larger than external diameter of a shaft part (14). The shaft part is passed through the head part by an angular shoulder that is formed through a convex rounded region (15) such that the convex rounded region extends up to a cylindrical lateral surface of the head part. An inner chamber (18) of the head part is in circular-cylindrical shape, and a half-spherical shaped transition section is provided between the head part and the shaft part. Independent claims are also included for the following: (1) a method for producing connection between functional elements (2) an assembly component for a punching unit.</p> |
