Bolt Tensioning

Bolt Tensioning is a simple and reliable method of applying a preload to a fastener assembly. Bolt Tensioning applies a force directly to the bolt and stretches it axially, eliminating most of the factors which provide control problems using other tightening methods such as torque tightening.
