ABSTRACT:
The present disclosure relates to self-piercing fasteners, such as studs, bolts or nuts, the method of attaching such fasteners to a panel and fastener installation apparatus, including the installation head and die button. The fastener includes a self-piercing and riveting annular wall which is driven into a panel supported against a die member by the installation head. The die member includes an annular die cavity surrounding a central projecting die portion which is telescopically receivable in the free open end of the fastener annular wall. The free end of the fastener annular wall includes a piercing surface which mates with a piercing surface at the outer edge of the projecting die portion to pierce a slug from the panel. The panel slug is then pressed into the opening in the annular fastener wall by the conical end of the projecting die portion and the free end of the annular wall is simultaneously deformed radially outwardly in the die cavity forming a rigid mechanical interlock with the pierced panel edge.
