11.2 Common Bolt Torque Values
Checking Bolt Torque
The tables shown give correct torque values for various
bolts and capscrews. Tighten all bolts to the torque
values specified in the table, unless indicated 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.
