ABSTRACT:
Disclosed herein is a bolt retainer for use as a component of an access panel fastener. The retainer comprises a grommet having an axial end and an aperture in open communication therewith. The grommet has a radial shoulder surface facing away from the end of the grommet which also has an internal surface extending toward the end of the grommet from the radially inner edge of the radial shoulder surface. The disclosed retainer has only two discrete retaining jaws in the aperture adjacent the radial shoulder surface and spring means biasing the jaws toward the axis. Each jaw is C-shaped and is substantially 180.degree. in circumferential extent. Each jaw also includes a boss adapted to enter the cylindrical surface of the grommet to limit jaw opening and the jaws present to the bolt a configuration of greater axial length than the pitch of the bolt thread.
