Torque figures indicated above are valid for non-greased or non-oiled threads and heads. Therefore, do not grease or oil
bolts or cap screws unless otherwise specified. When using locking nuts, increase torque values by 5%.
* Torque value for bolts and cap screws are identified by their head markings.
