摘要： A nut and stud assembly (10) for securing workpieces via threaded engagement of the stud (14) with one of the workpieces and engagement of the nut (12) with another of the workpieces and with the nut preassembled on the stud with the stud having a stop preventing the nut from advancing further on the stud until the stud has reached a preselected position in the one workpiece whereby the nut and stud assembly will function similarly to a headed bolt until the preselected position is attained and thereafter the stop will permit movement of the nut on the stud through such stop and be free running to function similarly to a separate nut and stud combination to a final clamp up of the workpieces.
