What Exactly is a Torque Wrench?
I am sure you have probably heard the term thrown around, especially at a mechanics shop, but a torque wrench is basically a specialized tool designed to deliver the precise amount of torque to a bolt or a nut like those of a vehicle wheel. It is important to not over tighten as this can damage the wheel.
Torque Wrenches and their Different Types
There are nine types of torque wrenches, but the ones most common number four. Each one has its own function and purpose. Depending on the type of job you are doing, you'd need to examine for yourself which one will work best for that project.
Note: I keep several items in my car in a kit located in the trunk. First is the torque wrench then a portable air compressor and jump starter combo, and finally road hazard reflectors. Okay, back to the types of torque wrenches.
Electronic Torque Wrench
For super precise readings an electronic version of this tool simply displays the exact torque on an LED display. Keep in mind these are mainly used by production lines and quality assurance due to their expensive and exact measurements, so they can be considered a little overkill if you just want one for your garage or vehicle.
What makes this tool so useful is its ability to utilize an internal computer that regulates the voltage. It has a backup safety feature that keeps the voltage under a certain level (a setting that the user can manipulate depending on the type of project their working on.
This type of torque wrench was invented in Europe (Germany) back in the 1980s. Surprisingly, this type of wrench can run without you even hearing it and can be connected to a standard electrical outlet.
