What is the torque requirement you need?

First things first; how much torque do you need for your application? 

  • Very light duty torque: If the range of your torque application is 15-75 ft. lbs. then you would only need a very light duty torque wrench. Some of the applications that fall in this range include fastening spark plugs, oil drain plugs, and valve cover bolts.
  • Light duty torque: Automotive repair industry mostly uses light duty torque wrenches that fall in the 30-150 ft. lbs. ranges for their tyre changing operations. Some of the applications that fall in this range include common repair needs like head bolts, lug nuts, and calliper bolts.
  • Moderate duty torque: Automotive fastening applications like fixing axle bolts, hub bolts, and light duty fasteners require a moderate duty torque in the torque range between 50 and 250 ft. lbs.
  • Heavy duty torque: Heavy duty automotive bolts require a torque between 120 and 600 ft. lbs. Some of the applications that need heavy torque include driveline components and bearings, as well as much of the work involved in transfer cases and differentials.
  • Very heavy duty torque: Very heavy duty automotive fasteners require a torque in the 200 to 1,000 ft. lbs. range. Some of the applications that would need a very heavy duty torque include fastening work on off-road vehicles and performance racing vehicles.
