Buying Guide – What is the best torque wrench on the market?

When it comes to tightening and loosening threaded parts like bolts and nuts, there is nothing better than using a torque wrench. That is why we have prepared this guide to buy the best torque wrench on the market, with the aim of reviewing its operation and the most important characteristics to take into account when we are comparing torque wrenches to choose a good and economical one.

What is a torque wrench and how does it work?

Many of us have “isolated” a screw or nut or what is the same, we have damaged the thread. This happens because we put too much force when squeezing. Each piece has its own “tightening torque”, which is nothing more than the force limit it needs to be properly tightened, but without damaging the thread.

As its name indicates, it is a pair of forces, the tightening that we apply to the resistance of the screw or nut. The tightening torque is expressed in units of force by the distance of the turn, that is, in Newton per meter (NM) or in Kilograms force per meter (Kgf-m). Torque wrenches are tools capable of measuring the tightening torque, in this way we do not damage nuts and bolts.


These tools can be of many types, however, the most used are the ratchet type, which allow the tightening torque to be adjusted and the wrench emits a “clack” sound when the correct tightening has been achieved. They usually have the adjustment system in the handle itself, but others, which are also very exact, have a scale on the head of the tool. As you tighten the part, the tool marks the tightening, when the necessary tightening torque is achieved, you just have to stop tightening and that’s it.

Of course, there are many models of all kinds and prices also vary a lot, but before asking how much it costs, let’s see other more relevant specifications.

Scope or tightening range

This is expressed in Nm and is the ability to recognize the different tightening torques. For example, a torque wrench can have a range of 2-14 Nm, 2-24 Nm, 10-80 Nm, etc. For example, if we wanted to tighten a metric 8 screw, a wrench with a range of 5-25 Nm would work perfectly.

If it is a motorcycle or any other vehicle, the most recommended in terms of tightening is to read the manufacturer’s instructions, since it appears there what is the tightening of each screw and nut. Oddly enough, properly tightened bolts and nuts can make our vehicles last longer in good condition.

square measure

The head of the cup can be one-half, three-eighths, or one-fourth of an inch. These measurements influence the tightening range, for example, the 1/4” wrenches will not reach a tightening of 210 Nm but will cover the range of smaller tightenings.


These are the ones that attach to the wrench to tighten. The glass must have the metric of the nut or screw that we need to tighten. However, we can always use different sockets with the same torque wrench using adapters.

click mechanism

This is very important because it is how you find out that the nut is already tight. It is a very simple system, but not all keys have it. It is best to make sure that yours will have this characteristic sound.


The best torque wrenches have been calibrated by a computer, but over time they can lose calibration, so it is good that the wrench supports a new one. This means that it can last much longer. As for calibration, some skill and knowledge are necessary, so we recommend going to have it done by a professional or, in any case, buying a key that comes correctly calibrated from the factory.

Finally, we recommend you not to get carried away by the offers of more accessories. It is great to have several sockets to choose from, however, the most important thing is the quality of the faucet, the calibration and the accuracy it offers.

Remember to think carefully about your own needs. Many people who need a simple wrench to adjust the motorcycle chain end up buying a large, complex and expensive wrench that, however, is impractical for its intended use. The more certain you are of what you need, the more you will get out of your new torque wrench.

How to use a torque wrench

To make repairs or adjustments on motorcycles or any other mechanism that requires screwing, it is very important to have the necessary tools for it. When it comes to screwing properly and without putting the components of the machine at risk, there are torque wrenches and in this article we will tell you how to use them.  

How to know what is the correct tightening

Components such as nuts and bolts have printed on some part of their surface or on the labels what is the tightening torque that is necessary to achieve the proper adjustment of the parts, in such a way that they work correctly and do not loosen when the mechanism is in operation or become distorted because the manufacturer’s recommended tightening force has been exceeded.

Although you can read the specifications given by the manufacturer to correctly fasten the bolts or nuts, if you do not use a torque wrench it is difficult to know when you have reached the correct tightening torque. On the other hand, with the key you just have to turn it until you hear and feel the clack in the tool that indicates that you have reached the correct tightening torque.

Make the adjustment torque

This is an easy task to do if you use your torque wrench. Start by taking the bolt or nut and tightening it with your hands until you feel resistance, that is, until you can no longer turn it by hand. If necessary, place the socket of the size corresponding to the size of the component you are adjusting on the machine on the head of the wrench.

Next, attach the socket to the component and start turning the key with some force as required until you hear the key click indicating that you have reached the component’s tightening torque. When you hear the click stop, otherwise you will exceed the torque.

How to calibrate it

Torque wrenches are factory calibrated in most cases, but can be knocked out of calibration by a heavy blow. However, you can recalibrate them yourself. To do this, put a mark in the center of the back of the key head; follow this indication straight to where you put your hand to take it by the handle. In that limit put another mark. Take the measurement between the two marks.

Insert only the head of the key in a vise and put the rest of its body in a horizontal position. Next, align the torque value of the tool according to the measurement you previously took after multiplying it by 0.97.

At the point marked on the handle of the key tie a weight or object weighing 9.07 kg; push as you move the handle toward the wrench head until you can no longer hear the clicks.

Care you must have

The torque wrench is a calibrated tool, so it is very important that it does not suffer strong shocks that could affect its calibration level. You should also not expose it to moisture and heat.

The most popular brands
