Abstract
A fastener system having a fastener and a fastener retention member is provided. The fastener includes a threaded portion, a head, and a shank portion extending therebetween. The threaded portion includes threads having a major diameter greater than a diameter of the shank portion. The fastener retention member includes a body member having an axial opening therethrough, and at least one shank engagement member protruding into the axial opening of the body member. The shank engagement members define a diameter smaller than the major diameter of the threads of the threaded portion of the fastener. The shank portion of the fastener is received in the axial opening of the fastener retention member and is axially movable therein and trapped between a position where the head of the fastener abuts the fastener retention member and a position where the threaded portion of the fastener engages the shank engagement members.
