1) Torque values in this table are not to override other specific torque specifications when supplied.
2) When using loctite, torque values in this table are only accurate if bolts are tightened immediately after
Loctite is applied.
* The proof strength of Grade 2 bolts is less for sizes 7/8 and above and therefore the torque values are less
than smaller sizes of the same grade.
