This appendix lists standard torque values, as shown in Table H-1, and provides general information for
applying torque. Special torque values and tightening sequences are indicated in the maintenance procedures for
Always use the torque values listed in Table H-l when the maintenance procedure does not give a
specific torque value.
Unless otherwise indicated, standard torque tolerance shall be ±10%.
Torque values listed are based on clean, dry threads. Reduce torque by 10% when engine oil is
used as a lubricant. Reduce torque by 20% if new plated capscrews are used.
Capscrews threaded into aluminum may require reductions in torque of 30% or more of Grade 5
capscrew torque. Capscrew threaded into aluminum must also attain two capscrew diameters of thread engage-
If replacement capscrews are of higher grade than originally supplied, use torque
specifications for the original. This will prevent equipment damage due to over-
