Blind rivet and method of making same

A self-plugging blind rivet for securing together apertured members comprises a tubular shell (11) having a tail end fact (16) at one end, a pre-formed radially enlarged head (13) at the other end, and a stem which extends through the shell and has a stem head (22) adjacent the tail end fact (16) of...

Beschreibung
Zusammenfassung:	A self-plugging blind rivet for securing together apertured members comprises a tubular shell (11) having a tail end fact (16) at one end, a pre-formed radially enlarged head (13) at the other end, and a stem which extends through the shell and has a stem head (22) adjacent the tail end fact (16) of the shell. The region adjacent the stem head (22) is of increased diameter relative to the rest of the stem shank and has a plurality of axial depressions (26) formed therein, the corresponding region of the shell being arranged to fill the axial depressions (16) in the stem and being harder than the material of the shell (11) in a region adjacent the radially enlarged head (13). In use and under axial compression leading of the shell (11), the shell (11) buckles in the region adjacent the member remote from the performed head to form a blind head in contact with said member so as to clamp together the apertured members.
