ABSTRACT:
Quick action fasteners, nuts, and end-to-end couplers, which eliminate the need for time-consuming and labor-intensive threading of nuts, couplers, and the like to helically threaded reinforcing rod and sections thereof and to other types of textured surface reinforcing rod, particularly in environments in which the fastener will be subjected to high loads and/or torques. Fasteners according to the invention include a housing, a plurality of nut segments, and an end cap for retaining the nut segments in a specially shaped bore defined in the housing. The bore includes a tapered section and an expansion section; the nut segments are formed, along interior segment surfaces, to be closely engageable to a corresponding section of the reinforcing rod. The nut segments are also shaped, along their exterior surfaces, to be congruent with tapered section of the bore. The nut segments are movable from locked engagement with the tapered section and the rod section to a release position in which the nut segments can be moved into the expansion section to slide or "ratchet" over the surface of the rod.
