Abstract
A self-attaching fastener and panel assembly wherein the free end of the tubular barrel portion is coined and deformed axially and radially outwardly against a planar die face into an annular shape having a planar annular bearing surface supporting the panel and a flat end face. The die includes a central post and an annular planar die surface extending substantially perpendicular to the longitudinal axis of the die member. The method of installation includes coining and deforming the barrel portion axially and radially eliminating cracking of the barrel, frictional resistance and hoop-stress.
