Bolt Tensioners
A hydraulic Bolt Tensioner is a lifting cylinder like device that is used to grip the threaded portion of the stud or bolt using a internally threaded puller bar and use a hydraulic cylinder ram to push a puller which in return pull/’stretches’ the bolt. Once the bolt is stretched the gap created is closed by tightening the nut.
