Abstract
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. A forging collar has a central aperture and is received in sleeve-like fashion over the shaft and is retained therewith. The forging collar includes a forging surface at an end most proximate to the annular flange wherein the forging surface is in deformable contact with the top of the shoulder. The forging collar further includes a first forging ring extending from the forging collar end and toward the annular flange for forging the host panel into engagement with the undercut.
