Frequently Asked Questions

The Importance of Torque and Preload

The first step to a secure bolted joint is achieving the correct torque and preload. Torque tightening involves applying a known rotational force to the assembly to achieve what’s known as preload, or clamp load. This is the tension in the bolt, which has been specified by the design engineer for best performance of the machinery. Torque tightening using correctly calibrated tools is normally sufficient to achieve a good preload for most industrial bolted joints. Remember that torque varies when tightening and untightening
