1. Always use the torque values listed above when specific specifications are not available
NOTE
Do not use above values in place of those specified In this manual, special attention should be
observed In case of SAE Grade 6, 7, and 8 capscrews.
2. The above Is based on use of clean and dry threads.
3. Reduce torque by 10% when 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 30%/o or more, unless Inserts are
used.
