torque wrench, as the fastening torque is affected by many
factors including the following:
• Voltage: Low voltage, due to a nearly discharged battery, will
reduce fastening torque.
• Accessory size: Failure to use the correct accessory size will
cause a reduction in fastening torque.
• Bolt Size: Larger bolt diameters generally require higher
fastening torque. Fastening torque will also vary according to
length, grade, and torque coefficient.
• Bolt: Ensure that all threads are free of rust and other debris to
allow proper fastening torque
