Bolt tensions shown in Table 1 must be decreased by 25% when other or no lubrication is used. Non lubricated bolts can have an efficiency of 50% less than the torque values stated. Indicative torques are shown only, different body gasket systems, different seating styles, different sizes & classes etc., will have different torque requirements. Furthermore, other stud grades can have much lower torques depending if class 1 or class 2, and or above variables.
