Abstract: A re-usable integrated plastic part (20), such as an automotive plastic trim panel (36) and fastener (22) for attachment to a support member (24), such as a steel frame. The fastener (22) includes a mandrel (26) integral with and extending transversely from the panel (36). A flexible component (30) coupled to the mandrel (26) includes a pair of rivets (32) disposed on opposite sides of the mandrel (26) for engaging the support member (24). The flexible component (30) also includes arms (56) bending at hinge points (62) upon engagement of the support member (24) by the rivets (32). The flexible component (30) includes an intermediate section (34) expanding to an installed intermediate width (wi) to maintain the rivets (32) in wedged engagement between the mandrel (26) and the support member (24).
