ABSTRACT:
Preferred embodiments (60, 70) of a fastener adapted to secure any selected one of a plurality of threaded members (S") are provided. Fastener (60) features substantially parallel spaced-apart flat plate members (2, 4) preferably folded from one piece to provide a resilient end fold (6) connecting them together at one end and which features respective apertures (28, 26) that are axially offset by a distance ("x") and have respective thread engaging edges (24, 20) about at least a portion of their respective peripheries that are oriented to cause at least one of plates (2, 4) to rotate relative the other a distance effective to enable apertures (28, 26) to align sufficiently to enable threaded members ("S") to advance rotationally therethrough with end fold (6) further adapted to impart a resistive force against the threads that is effective to enhance the secured relationship therebetween. Fastener (70) differs from fastener by being adapted such that threaded members ("S) cause the plate members (32, 34) to move in substantially opposite parallel directions rather than rotate relative each other.
