9.2. Bolt Torque Values

Tables 9.2 and 9.3 give correct torque values for various bolts and capscrews. The bolt

diameter is measured to the outside of the threads. When tightening all bolts, tighten the

nut on the bolt to the torque specified in the tables, unless otherwise specified. Do not

replace or substitute bolts, nuts, or other hardware that is of lesser strength than the

hardware supplied by the manufacturer.

Torque values indicated below are valid for non-greased or non-oiled threads and head,

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%.
