  1. Accuracy

This is one of the most important things to consider when buying a torque wrench. Torque wrenches have different accuracies. Always try to find a wrench with an accuracy of plus or minus 5%. It would be even better if you can get a smaller amount of that. Because precision is always important in most of the tasks that a torque wrench will be used for, it is highly recommended that you should look for the accuracy of each one you pick.

  1. Type

There are some several types of torque wrenches that you should know. When buying a torque wrench, you should know the purpose of it to select the right one.

  • Beam Torque Wrench

This is the oldest type as we handed it down from generation to generation. It works by applying circular force to the handle clockwise or vice versa. If you need to tighten the bolt, just turn the wrench’s handle clockwise. If you want to loosen or detach the bolt, turn the wrench’s handle in counterclockwise. Really easy! However, there are still some disadvantages. One is that it is unable to provide any type of physical or audible feedback indication after reaching the desired level of torque. And the other is that most models can only be used in one direction for tightening nuts or bolts. A beam type of wrench cannot provide a versatile direction choice.

  • Micrometer Torque Wrench

If you are considering buying the most used and most versatile torque wrench, you will probably look out for the Micrometer Torque Wrench. To set up the torque, all you need is to twist the handle until it reaches the correct torque setting on the barrel of the tool. Rotating the handle clockwise tightens a spring inside. When you apply torque to a nut or bolt, the tool will click when the correct torque has been reached. The biggest advantage of the Micrometer wrench is its flexibility for either left or right-hand operations. One of the disadvantages is that because of the force being applied to wearing parts such as an internal coil spring, they require regular recalibration.

  • Electronic Or Digital Torque Wrench

Electronic or Digital torque wrenches have a digital readout screen which let you set the torque limit as your desire. Of course, it will be more costly than the beam one. But electronic or digital wrenches have come down in price in the last few years. Now you can afford one in most automotive stores.
