Can I Loosen or “Breakout” Studs using Hydraulic Stud Tensioners?
Hydraulic Stud Tensioners are frequently used to loosen, or breakout, studs. It is important to protect the stud threads from damage and from corrosion during the time between makeup and breakout. The Hydraulic Stud Tensioner eliminates nut–to–flange friction, but you can only apply a limited torque to break the friction between the stud and nut threads. The easiest way to protect the exposed threads is to lubricate them and to then thread an additional nut over them.
