English
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.
Material: The type of material and surface finish of
‑
the material will affect fastening torque.
Fastening time: Longer fasten ing time results in
‑
increased fastening torque. Using a longer fastening
time than recommended could cause the fasteners
