CAUTION: Capscrews threaded into aluminum may require reductions in torque of 30% or more, unless inserts are used.
NOTE: Do not use above values in place of those specified in the engine groups of this manual; special attention should be ob-
senmd in case of SAE Grade 6, 7, and 8 capscrews.
1. Always use the torque values listed above when specific specifications are not available.
2. The above is based on use of clean and dry threads.
3. Reduce torque by 10% when engine oil is used as a lubricant.
4. Reduce torque by 20% if new plated capscrews are used.
