An access panel fastener in which a threaded fastener element is captured within an annular retainer affixed to the access panel and is movable axially relative to the retainer between a securing position and a hold-out position. A plurality of jaws in the retainer are resiliently biased radially inwardly by a surrounding cochlear spring to retain the fastener element in the hold-out position and enable ready movement of the fastener element past the jaws to the securing position. The access panel fastener includes a complementary threaded fastener having a self-locking mechanism which utilizes a collar of synthetic resin material.
