Grinding mills have critical fasteners that hold the structure together. If they have incorrect pre-load and loosen the ramifications are dire. Historically these bolts were torqued to 75% of the yield strength of the material. When you consider that the torque to tension relationship is normally regarded as + / - 25% it’s easy to see how they can easily be over or under tightened.
