ABSTRACT:
Disclosed is a quick fastening quick releasing nut-and-bolt assembly in which the bolt has finger elements disposed along the bolt's longitudinal axis. The finger elements have sets of accurate thread segments matable with complimentary sets of radially inward facing arcuate thread segments on the inner diameter of a nut. The nut's inner diameter includes smooth semi-cylindrical surfaces circumferentially alternated with the nut's sets of thread segments. The nut has a central core body sliding upon radially inner surfaces of the finger elements so as to keep the finger elements in bearing relation with the nut's inner diameter. The assembly has a first, unlocked configuration in which the bolt's thread segments face the smooth surfaces on the nut's inner diameter. The assembly has a second, fastening configuration where the bolt's thread segments are engaged with the nut's thread segments.
