Torque specifications define how tight fasteners should be tightened to achieve the correct clamping force that holds parts together under load, vibration, and temperature changes. When the right torque is used, joints maintain consistent preload, reducing the chance of loosening, wear, or structural damage. If torque is too low, fasteners can loosen and joints may separate, leading to wear, leakage, or failure. If torque is too high, threads can strip or parts can crack or be overstressed. Therefore, following the specified torque ensures safety, reliability, and longevity of structural components, taking into account lubrication, materials, and the particular assembly sequence.
