TORQUE VALUES FOR THREADED FASTENERS
This WP lists standard torque values (Table 1) and provides general information for applying torque.
Special torque values and tightening sequences are included in the maintenance procedures for
Always use the torque values listed in Table 1 when the maintenance procedure does not give a specific
Unless otherwise specified, standard torque tolerance shall be 10%.
Torque values 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. Capscrews threaded into aluminum must also attain two capscrew diameters of thread
If replacement capscrews are of a higher grade than originally
supplied, use torque specifications for the original. This will
prevent equipment damage due to overtorquing.
