ABSTRACT:
Profiled bolt mounting unit for mounting on a structural member, comprising a blind rivet body having a sleeve and a flange for abutting against the structural member provided for mounting purposes with a mandrel having a setting head and a pull stem which may be gripped by a setting tool and detached from the mandrel at a predetermined breaking point (break neck) after exceeding a certain pulling force. The predetermined breaking point is separated by such a distance from the flange that the portion of the mandrel between the flange and the predetermined breaking point acts as a profiled bolt, whereby the mandrel portion remaining inside the blind rivet body after the setting process projects the profiled bolt portion away from the flange.
