This work package lists standard torque values and provides general information for applying torque. Special
torque values and tightening sequences are indicated in the maintenance procedures for applicable components.
1. Always use torque values listed in Tables 1 and 2 when a maintenance procedure does not give a specific
a. Table 1 provides torque limits for SAE standard fasteners.
b. Table 2 provides torque limits for metric fasteners.
2. Unless otherwise indicated, standard torque tolerance shall be ± 10 percent.
3. If the maintenance procedures do not specify a tightening order, use the following guides:
a. Unless otherwise specified, lightly lubricate threads and mating surface of the head on fasteners with
clean oil (OE/HDO-10).
b. When tightening fasteners above 30 lb-ft (41 Nm), use the torque pattern but only tighten to 70 percent of
final value (multiply final value by 0.7). Repeat pattern until final value is reached.
Tighten circular patterns using circular torque pattern and tighten straight patterns using straight torque

If replacement capscrews are of higher grade than those originally supplied, use torque
specifications for the original. This will prevent equipment damage due to overtorquing.
