Abstract

A fastening element (1), in particular for blind riveting, has a setting head (4), a deformation segment (2) and a shank end (3). The deformation segment (2) is arranged between the setting head (4) and the shank end (3). The fastening element (1) is hollow, optionally having a mandrel (7) inside the fastening element (1). The mandrel includes a head (23) and a foot (24) at least tension-resistantly connected to the shank end (3). The shank end (3) includes a punching edge (6) extending substantially along the outermost periphery of the shank end (3). Also identified are a process for setting the fastening element (1), a riveted connection to the fastening element (1), a device for setting the fastening element (1), an employment of the riveted connection obtained, and a die suitable for setting the fastening element (1).
