Patent ID: 6905298

Claim:
A nut assembly for joining two or more workpieces together comprising: a first fastener member having a first generally cylindrical inner bore provided with a first set of threads therein, a second fastener member provided with a second set of threads on an exterior surface thereof for threadable engagement with said first set of threads, said second fastener member having a second generally cylindrical inner bore provided with a third set of threads therein, said first set of threads, said second set of threads and said third set of threads all being cut in the same direction and being of approximately the same pitch, a threaded member having a shank including an unthreaded portion longer than coaxial bores in said workpieces through which said threaded member extends, said threaded member further having a conventional thread shank interface, whereby as said threaded member is threadably advanced into said third set of threads of said second fastener member, said third set of threads of said second fastener member contact said conventional thread/shank interface of said threaded member, with further relative advancement rotation between said first fastener member and second fastener member causing said first fastener member to be advanced past said conventional thread/shank interface of said threaded member and contact a said workpiece adjacent said nut assembly.
