TING INSTRUCTIONS
TIGHTENING TORQUE
The fastening torque is affected by a wide variety of factors, including the those listed below. After
fastening, always check the torque with a torque wrench.
Voltage:
Low voltage, due to a nearly discharged battery, will reduce fastening torque.
Socket size:
Failure to use the correct socket 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.
Material:
The type of material and surface finish of the material will affect fastening torque.
NOTICE:
Before starting your job, always perform a test operation to determine the proper fastening time.
WARNING!
• Do not over-tighten, because the force of the impact driver can break the fastener. Keep the impact driver
pointed straight at the fastener to avoid damaging the fastener head.
