Table 12 Torque Table
NOTE
Castellated nuts requiring cotter pins should be tightened initially to the lower value. Torque can then
be increased up to the maximum limit in order to install the cotter pin. A thick or thin washer may be
added under the nut as required in order to maintain within tolerances.
