APPENDIX H

TORQUE LIMIT S

H-1. SCOPE .

This appendix Iists 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

applicable components.

H-2. GENERAL .

a. Always use the torque values listed in Table H-1 when the maintenance procedure does not give a specific

torque value.

b. Unless otherwise indicated, standard torque tolerance shall be + 10%.

c. 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.

d. Capscrews threaded into aluminum may require reductions in torque of 30% or more of Grade 5

capscrews torque and must attain two capscrew diameters of thread engagement.
