Torque figures indicated are valid for non-greased
or non-oiled threads and heads unless otherwise
specfied. Therefore, do not grease or oil bolts
or capscrews unless otherwise specified in this
manual. When using locking
elements, increase torque values
by 5%.
* GRADE or CLASS value for bolts and capscrews
are identified by their head markings.
