1) Torque values in this table are not to override other specifi c torque specifi cations 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.
