10.2 BOLT TORQUE
CHECKING BOLT TORQUE
The tables shown below give correct torque values for various bolts and capscrews. Tighten all bolts to
the torques specified in chart unless otherwise noted. Check tightness of bolts periodically, using bolt
torque chart as a guide. Replace hardware with the same strength bolt.
Torque figures indicated above are valid for non-greased or non-oiled threads and heads unless oth
-
erwise specified. Therefore, do not grease or oil bolts or capscrews unless otherwise specified in this
manual. When using locking elements, increase torque values by 5%.
* Torque value for bolts and capscrews are identified by their head markings.
