The Best of Both Worlds – Hydraulic and Mechanical Tensioning
In this video, Steve Busalacchi from Superbolt and Steven King from Boltight demonstrate the benefits of using tensioning instead of torquing as a bolting solution. They also discuss the differences between hydraulic and mechanical tensioning.

A hydraulic bolt tensioning tool provides a quick, easy, and safe method for tightening large-diameter bolts to high and accurate preloads. It does not use torque or require forceful turning of the nut or bolt, like impact wrenches, flogging spanners, or hydraulic torque wrenches, where friction is a common enemy.
In 1984, Superbolt invented the multi-jackbolt tensioner (MJT), which took the large, cumbersome torque commonly associated with hex nuts and divided it among several smaller jackbolts. Since then, Superbolt MJTs have revolutionized the tensioning industry…and tensioning has never been easier.
