Abstract:
A blind rivet for connecting a plurality of components, comprising:a rivet shank including an essentially hollow cylinder having contiguous surfaces, said rivet shank having an inner diameter and an outer diameter and a first end and a second end;a rivet shaft penetrating the rivet shank and the set head coaxially and essentially without play;an annular set-head fixedly attached to the first end of the rivet shank and having a set-head end remote from the rivet shank and presenting a support surface approximately perpendicular to the rivet shaft, said set-head having an outer diameter greater than that of the outer diameter of the rivet shank and essentially forming with the rivet shank a T-shape in cross section;a shaft head fixedly attached to the end of the rivet shaft remote from the set head end of the rivet shank, said shaft head having a diameter that is greater than the inner diameter of the rivet shank; anda plurality of break-off groves arranged axially and in series along the rivet shaft, said break off grooves having a depth which constricts the diameter of the rivet shaft, wherein said break-off grooves are disposed on the rivet shaft such that, when the rivet shaft is displaced in a direction of the set-head with respect to an initial position as a result of a riveting process, one break-off groove is essentially flush with the set-head end remote from the rivet shank.
