Note

'The values listed above are for clean and dry parts free of lubricants and thread lockers. A lubricated fastener must have the torque values reduced 25 - 30% from the above ratings. Keep in mind that this is only an estimated value. It may provide satisfactory performance. Every application needs to be evaluated on its onwn to determine the optimum torque for each application.
