ABSTRACT:
A symmetrical self-attaching female fastener including a body having a bore, and identical integral tubular barrel portions extending from opposed ends of the body coaxially aligned with the bore. The installation method includes driving either barrel portion through an opening in a panel, which may be formed by piercing the panel with the barrel portion, and simultaneously deforming both barrel portions radially outwardly and inwardly, wherein one barrel portion entraps the panel and the other exposed barrel portion is folded at an acute angle relative to the bore to reduce the overall length of the assembly.
