Heavy Duty Inch Torque Wrench Auto locking torque-adjusting mechanism; 40” length fully extended; 3/4" drive provides up to 410 Ft-Lb of torque, enough for the most heavy duty work—industrial machinery, semi-trucks, and more
Precise Turn the handle of the adjustable torque wrench clockwise to up the torque and counter clockwise to decrease the torque; Wrench is accurate to +/- 4%; Over or under torquing fasteners makes them more likely to fatigue or loosen from use
Safe Torquing The 400 ft lb. torque wrench makes a loud click when you’ve tightened your fastener to the desired torque; To keep your wrench accurate do not use it as a nut buster as this can cause the wrench to become uncalibrated
Includes Instructions Simple to follow instructions included with torque wrench set; If you use a 3/4 drive extension, make sure to figure out how the torque rating changes, as the flex in the extension alters the output torque
