The rivet (1) has a rivet shank (4) provided with a concentrically arranged recess (5), where the shank opens into a rivet foot (6) that serves as a blade. A lower side (3) of a rivet head (2) is formed in round shape, where diameter (dk) of the rivet head is less than or equal to 1.3 times of diameter (ds) of the shank. The recess is filled with an incompressible medium i.e. self-curing adhesive, where diameter of the recess is 3.2 mm. A cutting surface (7) has a chamfer (8) running into the recess. |
