<p>A stud tensioning apparatus includes an array of arcuate jaw segments that are movable inwardly to cause grooves on the segments to engage the threads of the studs. The tensioning force is applied to the segments by a pull member that has hangers received by apertures in the segments. The hangers fit loosely into the apertures, permitting the segments to move pivotably in two perpendicular directions to compensate for misalignment between the stud and the tensioning apparatus.</p> |
