Bolt Torqueing and Tensioning
The objective is to stretch the bolt or stud to a predetermined load. The stretching is accomplished by turning the nut, which pulls the shank due to the ramp angle of the threads.
Bolt tensioning works by preloading the bolt, stretching it before the nut is tightened. The tensioner is clamped to the bolt’s threads and pushes against the flange in the surface being bolted. This provides a very consistent amount of stretch to the bolt, ensuring consistent bolt stretch and clamping force.
