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.
