A captive fastener system having a fastener and a retention member is provided. The retention member includes a cylindrical body having a flange at one end thereof. Work piece retention members project outwardly of the body for securing the retention member in a bore of a work piece. A plurality of dimples project inwardly in the retention member, and are narrow in a circumferential direction and elongated in an axial direction of the body. The dimples frictionally engage a shank of the fastener, to hold the fastener in the retention member.
