SUPPORTING INFORMATION
TORQUE LIMITS
SCOPE
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.
GENERAL
CAUTION
If replacement capscrews are of higher grade than originally supplied, use torque
specifications for the original. This will prevent equipment damage due to overtorquing.
a.
Always use torque values listed in Tables 1 and 2 when a maintenance procedure does not give a specific
torque value.
1.
Table 1 provides torque limits for SAE standard fasteners.
2.
Table 2 provides torque limits for metric fasteners.
b.
Unless otherwise indicated, standard torque tolerance shall be 10 percent.
c.
Torque values listed are based on clean, dry threads. Reduce torque by 10 percent when engine oil is used as
a lubricant. Reduce torque by 20 percent if new plated capscrews are used.
