ABSTRACT:
The bolt, in the one-way nut and bolt combination, includes a head, a stem, and bolt threads on said stem. A longitudinal channel is defined on the bolt stem by a plurality of notches extending through the crests of the threads. In one embodiment, each notch is defined by a radially aligned surface and an angularly displaced surface. The nut, in one embodiment, has a threaded bore that is complimentary to the bolt thread and includes at least one longitudinal cut-out. The nut further includes a compressible tine extending into the cut-out. The compressible tine has a body portion and a substantially radially aligned distal end portion. The distal end portion of the tine and the cut-out defines a narrow mouth leading to a wider throat deeper in the cut-out. The nut thread and the bolt thread cooperatively permit a user to translate the nut along the bolt threads by means of one-way rotation. The tine is alternately flexed inboard into the cut-out, by the bolt threads, and then released when the tine is disposed in the longitudinal channel. The longitudinal channel and respective notches forming the channel prevent counter-rotational movement of the nut on the bolt when the distal end of the tines abuts the radially aligned surface of the notches. In another embodiment, the tine is located on an insert. The insert is mounted in the nut. In another embodiment, the tine is formed at one terminal end of a U-shaped or a J-shaped clip. The clip is slipped over a sheet panel to thereby form a locking nut bore.
