Always use the torque values listed above when specific specifications are not available
1.
Note: Do not use above values in place of those specified in the engine groups of this manual, special attention should be
observed in case of SAE Grade 6, 7 and 8 capscrews.
iS based
on use of clean and dry threads
2 The above
Reduce torque by 10% when engine 0il is used as a lubricant
3
4. Reduce torque by 20% if new plated capscrews are used
Caution: Capscrews threaded into aluminum may require reductions in torque of 30% or more, unless inserts are used.
