A hybrid panel fastener for use in conjunction with a nut and cage assembly for fastening and unfastening a composite access panel that is galvanically compatible with the composite access panel, suitable for low observability applications, and high cycle usage includes a composite shank member and a metallic sleeve member integrated in combination. The composite shank member includes an interface segment having a peripheral engagement surface, a body segment contiguous with the interface segment, and a head having a torque-input surface contiguous with the body segment. The metallic sleeve member has an externally threaded surface and an integration bore that is complementary to the peripheral engagement surface of the interface segment. The metallic sleeve member is mated with the composite shank member by press fit insertion of the metallic sleeve member onto the interface segment wherein the wall defining the integration bore mechanically engages the peripheral engagement surface of the interface segment to preclude relative rotation between the composite shank member and the metallic sleeve member. A retention mechanism for use in combination with the hybrid panel fastener is mounted in combination with the composite access panel and operative to retain the hybrid panel fastener in combination with the composite access panel by mechanically engaging the hybrid panel fastener upon threaded disengagement thereof from the nut and cage assembly.
