Problem: The previous method - customer fabricated support track to support extremely heavy impact wrench - caused problems with improper torque and thread galling. It was also unsafe and time consuming.

Solution: Superbolt® Mechanical Tensioners were easily installed with common air tools as seen in the picture (torque should be verified with a torque wrench). Proper bolt load with no thread galling is achieved.

Tension on bolt = 428,400 lb.
Equivalent Hex Nut Torque = 18,925 ft-lb
Jackbolt Torque = 233 ft-lb
