A reversible threaded fastener system which provides holding of a nut in a f ully conjoined state with respect to a bolt, yet the interrelationship therebetween is fully reversible and is accomplished without friction and without inelastic deformation. Included is a bolt having a threaded shank, a nut having a threaded bore for being threadably engaged on the threaded shank of the bolt, and a washer non-rotatably interfaced with the shank and provided with a plurality of radial washer waves. The washer is held in non-rotatable relation with respect to the bolt by the shank and the bore of the washer being mutually asymmetric. In a first preferred embodiment, the inner face of the nut is provided with a plurality of radial nut waves which correspond to the washer waves, and the washer is resiliently deformable. In a second preferred embodiment, the nut is provided with a plurality of radial nut waves which correspond to the washer waves, the washer is not resiliently deformable, and the nut is resiliently deformable. In a third preferred embodiment, the nut is provided with a plurality of radial nut waves which correspond to the washer waves, the washer is not resiliently deformable, the nut is not resiliently deformable, and the head of the bolt is resiliently deformable.
