CAUTION: Ensure fastener and/or system will withstand the level of
straight at the fastener.
Always check torque with a 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 coeffi cient.
