Abstract
The fastener includes a pin and a grommet for attaching a primary panel to a secondary panel. The pin includes two dual-height finger assemblies and a circular flexible flange or umbrella head. A primary panel through a first range of thicknesses is sealingly engaged between the flexible flange and the fingers of a first height of the dual-height finger assemblies, and a primary panel through a second range of thicknesses is sealingly engaged between the flexible flange and the fingers of a second height in the dual-height finger assemblies. The pin further includes a male element with external serrated ridges. The male element engages a passageway in the grommet which includes an internal ridge for engaging the external serrated ridges. The grommet further includes a pair of spaced disks for engaging an opening in a secondary panel.
