Abstract of the Disclosure An improved fastener is provided with retainer elements which are utilized to prevent undesired movement of the fastener relative to an associated member. In one embodiment of the invention, the retainer elements are resiliently deflectable spring fingers having relatively narrow base portions and relatively wide free end portions with sharp peaks which penetrate the associated member to prevent reverse rotation of the fastener, that is rotation of the fastener in a direction tending to loosen the fastener. When the threaded fastener is being rotated in a first direction to tighten it, the spring fingers are deflected into recesses formed in the fastener to prevent gouging or marking of the member. Upon the application of a force tending to loosen the fastener, the free end portions of the spring fingers penetrate the member and dig in to prevent loosening movement of the fastener.
