A quick-clamping nut for permitting rapid engagement with an externally threaded member, such as a bolt, with a minimum of turning to lock a first member to a second member, the second member carrying the threaded bolt. The nut includes a tubular housing having a pair of elongated, similarly configured segments carried therewithin, the segments each including outer ends having an internal thread formed therein. The elongated segments also include outwardly facing tapered surfaces, and inner ends that are secured to the tubular housing and that carry biasing means to urge apart the outer ends of the segments. A clamping cone is provided having a through bore and an outer surface adapted for engagement with the first member, an inner tapered surface for cooperative engagement with the outwardly facing tapered surfaces of the elongated segments so that axial movement of the elongated segments into the clamping cone operates to urge the threaded ends of the elongated segments inwardly toward each other to engage the internal threads therein with external threads on a threaded member. Inward movement of the threaded ends of the elongated segments is limited by an annular shoulder that is carried by the clamping cone to engage with the inner surfaces of the threaded segments and thereby limit the inward movement thereof to prevent binding of the interengaged threads.
