Bolt Torque Factors
LUBRICANT OR PLATING TORQUE CHANGES
Oil / Anti-sieze Reduce torque 15% to 25%
Dry Film (Teflon or moly based) Reduce torque 50%
Dry Wax (Cetyl alcohol) Reduce torque 50%
Chrome plating No change
Cadmium plating Reduce torque 25%
Zinc plating Reduce torque 15%
Information provided by raskcycle.com
Torque values should be reduced if using lubricants such as anti-seize.
