Actual torque varies with lubrication and clamp load - use this four-step approach instead.
Confirm Clamp Load
Get the required preload from your engineer or connection design.
Check Lubrication
Plain, galvanized and lubricated bolts each carry a different friction (K) factor.
Apply T = K · D · P
Torque = K-factor × bolt diameter × required clamp load.
Verify With Calibrated Wrench
Spot-check with a calibrated torque wrench before sign-off.
