Usage Tips

Always use a calibrated torque wrench.
For angle-torque bolts (e.g., head or rod bolts), first torque to the specified Nm, then rotate the correct angle.
Replace any torque-to-yield components after removal.
Apply proper lubrication to threads as specified for reliable torque application.
