ABSTRACT:
A method for connecting piping system components, such as a valve and a pipe fitting, using a pair of half-height nuts in place of a single full-height nut on each stud. Each first half-height nut is torqued on its associated stud while a stud tensioner exerts an axial pull on the stud. Each second half-height nut is torqued onto the stud, using a standard torque wrench, after the stud tensioner is removed. The two nuts together produce a combined nut strength capable of withstanding the tensile force on the associated stud.
