Abstract: A fastener for thin panels has a shank with a deformable collar which works in conjunction with a configured mating panel to produce enhanced attachment forces, especially in the case of very thin panels. The mating panel is prepared with a round mounting hole with cross-cut openings or slots. The panel is stamped into a conical section in a preparatory step before installation to provide the fastener with snap-in engagement prior to final pressing. The fastener shank has an undercut located immediately below the collar which is snapped into the prepared hole. Once snapped in, a punch and flat anvil are used to press the deformable band of the fastener tightly against the prepared panel, capturing the panel rigidly between the deformable band and a base of the fastener. During pressing, the material of the fastener collar will also flow into the slots of the panel to prevent rotation.
