A fastener element including a barrel portion, a first radial flange portion integral and coaxially aligned with the barrel portion and a second radial flange portion having a diameter greater than the first radial flange portion coaxially aligned with the first radial flange portion including an annular face having circumferentially spaced radial ribs and a method of installing the fastener element which includes forming an opening in a panel which receives the barrel and first radial flange portions, wherein the panel is deformed radially inwardly against the first radial flange portion and the first radial flange portion is preferably deformed radially outwardly forming a secure fastener and panel assembly.

Fastener, method of attaching a fastener to a panel and fastener and panel assembly

A stud for installation in a host panel and for fastening a component to the host panel includes at least one shaft having a longitudinal axis. An annular flange extends radially from the shaft at a substantially right angle with respect to the longitudinal axis. A shoulder for engagement with the host panel has a top adjacent to the shaft and a base adjacent to the flange. The shoulder extends radially from the shaft wherein the shoulder and the flange define an undercut therebetween at the base of the shoulder such that a diameter of the shoulder is smaller at the base than at the top. At least one anti-rotation tab is located intermediate between the shoulder top and the flange, and is aligned for engagement with the host panel.
