1. Always use the torque values listed above when definite specifications are not available.
Note: Do not use standard values In place of those specified in other sections of this manual; special attention should be observed
when using SAE Grade 6. 7 and 8 capscrews.
2 The above is based on use of clean and dry threads.
3. Reduce torque by 10Svwhen engine oil Is used as a lubricant.
4. Reduce torque by 20% If new plated capscrews are used.
Caution: Capscrews threaded into aluminum may require reductions In torque of 303% or more, unless inserts are used.
