6.2 Torque Specifications
The following torque values are to be used on all fasten-
ers unless otherwise specified.
Lubricated refers to fasteners in the “As Received” condi-
tion, which is normally a light preservative oil coating on
unplated fasteners and no oil coating on plated fasten-
ers. No special steps are taken to add further lubrication
prior to assembly. Dry refers to parts that have been
degreased, both mating parts.
