ABSTRACT:
A method of attaching a fastener assembly to a member is disclosed. The fastener assembly includes a male fastener element which is fastened to a female fastener element wherein the male fastener element is adapted to engage and pierce through a panel. The female fastener element is adapted to rivet itself to the panel thereby forming a secure mechanical interlock between the female fastener and the panel. In a preferred embodiment, the female and male fastener include threaded surfaces which cooperatively engage one another thereby permitting the male fastener to be easily removed and used to fasten a structural member, or the like to the female fastener/panel assembly. While the fastener assembly is particularly suited for self-piercing applications, it may be used equally well in pre-pierced panel applications.
