ABSTRACT:
A fastener to retain at least two members together under spring tension including a bolt having a fastener head shaped with two lateral extending protrusions respectively forming two shoulders for engagement of an outside surface of one of the members to be secured together. An opening is provided through the members to be secured together and at least the opening through the latter-mentioned member which is to be engaged by the shoulders of the fastener head is generally contoured to the shape of the fastener head such that the fastened head freely passes through this opening in keyhole fashion and the bolt is turned so that the shoulders of the fastener head ride up onto this outside surface clamping the members together under spring tension. Lock recesses may be provided in the outside surface of the member closest to the fastener head to receive the shoulders of the fastener head in locking engagement.
