ABSTRACT:
An integral tensioner assembly mountable on a stud selectively to insert and remove the stud as from a pressure vessel or the like, or to place the stud under tension so that a holding nut can be freely turned on the stud to tighten or loosen the stud connection to the pressure vessel. The assembly includes a housing which carries a plurality of nuts operable in selective pairs. Each of the pairs of nuts has a separate nut turning mechanism which is carried by the housing.
The integral stud assembly is fastened to the vessel to operate on the stud without the need of extra bulky temporary connection systems.
