Abstract
A w-base fastener that may be used in many applications, including numerous applications throughout the automotive industry, combines the functionality of a w-base fastener with the serviceability of other fasteners. The w-base fastener of the invention provides the ability to service the w-base fastener without damaging the panel or hole in which the fastener is inserted. This is accomplished by incorporating a break joint configured to break at a predetermined load. This break joint permits the fastener to be easily extracted when it breaks under the predetermined load. As the two sections of the fastener are separated, hooks on the fastener body engage tabs on the legs and pull the legs of the w-base fastener inward to prevent interference between the legs and the panel as the fastener is extracted from the hole.
