Abstract: A fastener includes an elongated shank equipped with longitudinally spaced ribs, and a clip having opposing collar sections connected for movement between first and second positions for engagement with the shank and for installation or removal of the clip from the shank, respectively. Internal tabs formed on the clip aid in maintaining engagement between the collar sections and the shank during application of external twisting forces on the clip.

Abstract: A fastener includes a threaded post and a nut formed with an internal threaded portion for threading onto the rod. A slot formed longitudinally in the post interrupts the threads and that is sized to slidably receive the threaded portion of the nut such that the nut slides freely along the length of the post. The nut is secured by sliding the nut onto the post until reaching a desired position, and then rotating the nut such that the threaded portion of the nut engages the threads formed on the post. The nut is secured into the desired position with an integrally formed locking tab that extends into the slot after the nut has been rotated onto the shank.
