• 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 fastening
time results in increased fastening
torque. Using a longer fastening time
than recommended could cause the
fasteners to be overstressed, stripped or
damaged.
Capacity
Your 1/2" (12.7 mm) impact wrench uses
sockets with 1/2" (12.7 mm) square drive ends.
