What are Torque Wrenches Used for and How to Get the Best One

For every fastener on every vehicle, the manufacturers specify exactly what needs to be the right tightening measure. This is not only to protect the drivers and passengers of the vehicle but for everyone that comes in its way or has to deal with it, like at the car wash. If you know what are torque wrenches used for, you will get a lot of head start at selecting your vehicle repairing methods when at the mechanic’s and knowing if it is done well.

Of course, it is the duty of them to fix it right, but it is your duty to make sure you are receiving the right thing.

To tighten nuts and bolts, the torque wrench is a tool that gives you predetermined torque value. “Torque” measures exactly how much force on an object makes it rotate. The pivot point of the Torque is the axis of the object on which you are willing to put pressure. Newton-meter, pound-foot, pound-inch are notable units of measurement of torque.

Now, a torque wrench allows the fasteners of a car or any vehicle to be tightened at just the right tension, without causing damage to the vehicle itself. Assembly, performance, and safety depend on setting this tension right. So whoever has the responsibility, should put his full practice to use.

What are Torque Wrenches Used for: Each Type and Uses

All the industries for all their different tasks use the torque wrench. Starting from construction to home and equipment maintenance, this is quite a handy tool to have around. However, it is essential to use it in places that require secure and tightening screws and nuts. To make sure that the recommended specifications of pressure to be put on these screws fit the one you tend to put, the wrenches are pretty useful. In the automotive industry often for vehicles, this tool is used.

The different types of torque wrenches that are available in the market differ in some basic points such as their reading and their adjustments. Their respective uses are mentioned here:

1. Dial Torque Wrenches

In terms of accuracy, these torques are often named with the few who can give you that. These are usually wider than the other wrenches and hence fail to be used in small spaces. Also, these are quite a bit popular in the Aerospace and Defence industry.

2. Micrometer Torque Wrenches

Manufacturing and cargo transportation industries often use this tool. When transporting large loads by ships, planes, and trains, it is necessary to know the weight of the load, because it can compromise the distribution of the freight. To stop the crew from being in danger and for the safety of the cargo itself, this is a great option.

3. Hydraulic Torque Wrenches

This uses the principles of hydraulics to set the torque and is frequently used in industrial settings.

4. Click Torque Wrenches

This is the best one to use for those of us who aren’t professionals when it comes to choosing the right torque. This is because when you hit the correct torque setting, it gives an audible click. They are the ratcheting type and are used frequently for the tightening and fastening we have been talking about so often here.

5. Beams Torque Wrenches

These are the most inexpensive and more accessible to use. A scale is used in a beam, and it stops at the number when you have reached the right torque. To employ force, there is an obvious handle on the wrench. When you use the beam, the scale does its job. This is also a daily-use tool like the one before it.

6. Electronic Torque Wrenches

The digital ones are not so much of a fuss and have an electric sensor that lets them check the torque measurement. The applied twisting force shows on the digital display. You can also save the readings you take using this one as it allows you to store data on a computer, with the memory chip inside.

Properly Using a Torque Wrench

Always use a torque wrench that is calibrated. When you purchase it, it will be on the package. There is a lock that you need to disengage before you rotate your handle and do the thing. Turn it off, and let the handle be in-line with the middle of the calibration and lock it again for proper future use without set-up time. For the click wrench, rotate the handle till you hear an audible click and stop then and there.

If you aren’t using it, put it in the lowest setting to preserve the accuracy. Do not use them to check an already-tightened fastener or to fasten them better. Loosen and re-torque with your new wrench if needed.

What Happens if You Don’t Use a Torque Wrench?

There are two reasons major enough for you to invest in a good torque wrench:

  1. If your nuts or bolts are too loose, they can come off midway and leave your vehicle unscrewed and dangerous to deal with.
  2. If your screws are too tight, the bolt shank will break and everything that was supposed to be together will come off.

Torque Wrench and Wheel Nuts

It is believed the tighter the lug nuts, the more safely it is fastened and a mistake often made by some mechanics. A loose wheel nut is dangerous, but so is an over-tight one. Checking the recommendations and using the best torque wrench will ensure a proper assembly of everything.


Now you know what torque wrenches are used for, and hopefully, you understand how important it is to invest in a good one. A torque wrench maintenance may sound just as easy as the buying. But you will have to be cautious or else there will be errors in reading when using your wrench. So for the sake of just one word: safety, get yourself some of the best torque wrenches out there and protect your car, friends, and family.
