Video
Boltight in action
This video walks through a hydraulic tensioner on a bolted joint. Hydraulic pressure stretches the bolt, the nut is run down while the bolt is stretched, and the pressure is released. The bolt is left with an accurate, even load.
Official Nord-Lock Group video, played from YouTube.A multi-stud tensioner tightens several studs at the same time from one tool. The video shows it set up on a flange and pressurised, so every stud gets the same load in one step. This saves time and gives an even joint.
