11.1 Bolt Torque
Checking Bolt Torque
The tables shown give correct torque values for
various bolts and capscrews. Tighten all bolts to
the torques specified in the table, unless specified
otherwise. Check tightness of bolts periodically.
IMPORTANT! If replacing hardware, use
fasteners of the same grade.
IMPORTANT! Torque figures indicated in the
table are for non-greased or non-oiled threads.
Do not grease or oil threads unless indicated
otherwise. When using a thread locker,
increase torque values by 5%.
NOTE: Bolt grades are identified by their head
markings.
