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 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.
