7.2 BOLT TORQUE
CHECKING BOLT TORQUE
The tables shown below give correct torque values for various bolts and cap screws. 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
otherwise specified. Therefore, do not grease or oil bolts or cap screws unless otherwise
specified in this manual. When using locking elements, increase torque values by 5%.
*Torque value for bolts and cap screws are identified by their head markings.
