ABSTRACT:
A fastener is provided which is particularly suited for joining two or more panel members together, such as a circuit board with the internal support chassis of an electrical enclosure or casing. The fastener is configured with a compliant lower portion, such that the fastener can be installed and secured with a simple push-through action which requires only a moderate force. Because assembly of the fastener does not require a rotational motion, assembly costs for automated assembly operations are reduced, while physical demands on an assembler are significantly reduced for manual assembly operations. The fastener is reusable, in that the fastener can be readily removed without being plastically deformed.
