   Multi-jackbolt tensioners (MJTs), registered under the trademark Superbolt or Supernut, are designed to decrease the torque required to tighten large bolted joints. One of the major problems associated with traditional bolt tightening methods is as the diameter of the bolt increases, the amount of torque required to tighten it increases in the third power of the diameter.

   The tolerances necessary to make the tools usable are listed in documents such as ASME/ANSI B18.2.2 for U.S. standards. [1] For instance, a bolt for a 1-inch nominal diameter thread might have flats that are 1.5 inches apart. The wrench for this bolt should have flats that are between 1.508 and 1.520 inches apart to allow for a little extra space.

   Bolt preload can also be controlled by torquing the bolt to the point of yielding. Under some circumstances, a skilled operator can feel the drop off of the work required to turn the torque wrench as the material of the bolt begins to yield. At that point the bolt has a preload determined by the bolt area and the yield strength of the bolt ...
