Problem: During design, it was realized that not enough space was available for a torque multiplier, and that if a “special” torque multiplier was used, it would probably not be available in the field.

Solution: Superbolt® Multi-Jackbolt Tensioners are easy to install and remove with only hand/air tools. The Torquebolts® used on this application dropped the required installation torque to values easily obtained with a small hand held torque wrench. This eliminated the need for a special design torque multiplier, or a re-design of the equipment to allow for a larger tool. Additionally, service in the field has been greatly simplified.
