ABSTRACT:
The present invention provides a method and apparatus for adapting standard threaded fasteners for use with a standard stud tensioner. An adapter has internal and external threads. The internal threads mate with the external thread of the stud to be tensioned. The external threads of the adapter engage the internal threads of a fastening nut having slots on the top thereof for engagement with a turning wrench of the tensioner. The adapter has a central threaded bore on the top portion thereof which is adapted to threadably engage the puller bar of a tensioning apparatus. The stud is elongated by actuation of the tensioner, via the puller bar, lifting the adapter as the stud is tensioned. When appropriate strain is achieved on the stud, the fastening nut is turned down to a fastened position and the stud then can be relaxed.
