Note: The above table has been composed based on using B7 Studs, Dow Corning Molykote Cu - 7439 lubricant, with friction
value of µ = 0.15 - Torque Values are in Ft Lbs.

TJ Tools offer this information as a guide only. Used at own risk. Any critical torque values should be nominated by your engineer relevant to your application and environment. TJ Tools offer this data relayed from other sources as a guide not a engineering document. No responsibility is excepted for any data entry errors. Factors such as type of lubricant, stud material, flange rating, Gasket choice, tightening technique, preparation, flange condition, and sequence all are factors in outcomes. A/F sizes and torque values will vary between manufactures based on gasket, lubricate etc. Break out Torque may increase by 100%
