Torque Wrench Buyer’s Guide
What is a Torque Wrench?
“Torque” is the name of a rotational force. Usually measured in Foot Pounds (ft/lb) or Newton Metres (Nm), this is how much you would tighten a fastener (such as a nut, bolt or screw). These fasteners are usually used as a force to clamp two or more things together.
It is important to measure this amount to avoid over or under-tightening anything. Overtightening will result in threads being damaged and in some cases, bolts can even be completely sheared, due to applying too much force. Under-tightening could lead to the two materials not being properly attached.
When using a calibrated torque wrench, the risk of overtightening and under-tightening is greatly diminished. It is important that the torque wrench is calibrated, to ensure that it is tightening everything to the level that the scale says it is tightening to.
The Importance of Torque Wrenches
It is very important to use torque wrenches when working on a range of tasks in the worlds of vehicles and construction. For example, imagine if you put a wheel back on a car, but only tightened the wheel nuts to finger tight. This leaves a high probability of the nuts working their way off while the car is being driven, leading to, at best, the tracking and suspension being thrown out, causing damage to both the car and the tires, and, at worse, the wheel falling off.
Other examples of things that must be tightened exactly could be when using a gasket. The gasket must be tight enough to be held together but loose enough to move. You can see how it would be difficult to just guess how much force you should be applying.
Different Types of Torque Wrenches
The most common type of torque wrench is a “click” type. The torque amount that you want would be set by a torque indicator, which is usually set by using a laser-engraved scale. You then attach a socket to the wrench and begin tightening the bolt that you need to work on. When you reach the torque that you have set, the wrench makes an audible clicking sound.
Once this happens, you should stop tightening – the required level of tightness has been reached. Just because the wrench has clicked doesn’t mean that it has stopped applying force to the bolt, and therefore you should not continue to tighten any more.
There are a few other main types of torque wrenches. These include beam-types, digital torque wrench, and torque sticks.
• Beam-types: this is essentially the original torque wrench. There are two parts to this style of wrench – the wrench itself and a pointer beam. When the wrench is twisted, the beam remains stationary. This means that torque can be measured on the scale. These types of wrenches do not stop you or alert you when you reach a certain tightness – they simply show you on the dial. Some argue that they are the best torque wrenches for accuracy because they never have to be calibrated.
• Digital Torque Wrench: these can be set to a certain torque using a digital display, which also sometimes shows the exact amount of force being applied. Digital torque wrenches work in many different ways, but they are arguably the easiest to read and human-error-free of all the options available.
• Torque sticks (aka torque limiters): these are small bars that are placed in between the wrench and a socket. Each bar is made differently so that it has an individual torque level, and when the required amount has been reached will bounce the socket away from what you are tightening, preventing it from going any further. Good quality torque sticks from trusted suppliers can be as accurate as a calibrated torque wrench – however, to be sure, it is always best to double-check the torque levels using a wrench you trust.
• Click types: as mentioned earlier.
The First Torque Wrenches
The first patent for a torque wrench dates back to the 1930s when beam torque wrenches came onto the scene. As the designs have been developed through the years since then, the main principle has remained the same: if you know the qualities of the material being used to tighten your fastener, you can measure how much it deflects when force is applied, and from that how tight it is becoming.
How to Use a Torque Wrench
Torque wrenches are not too complicated to use. On a click torque wrench, the torque setting must be selected, using the scale or dial, the socket attached, and the torqueing begin. Depending on the type of torque wrench you have, the wrench will probably either click or beep at the point where you have reached that set, desired torque. At this point, you should stop applying force. All of this will be explained in the manual which comes with the torque wrench.
On a beam torque wrench, the torque setting is not applied. The wrench simply measures how much force you are applying, and you stop when you reach your required amount.
Unless specified, do not lubricate the nuts/bolts you are tightening. It is also sometimes useful to tighten your fasteners halfway, and then all the way. This is particularly the case when you are attaching gaskets, as you need it to be an even covering of the surfaces it is between, without cracking or deforming in any way.
Sometimes you may need an extension. Different sizes of extensions can be used when you need a torque wrench. These will vary in length, usually from 1 inch to 6 inches. Although these are very useful when working in awkward spaces, the use of an extension makes the torque wrench slightly less accurate, because some of the force is being absorbed by the extension itself twisting. Therefore, the torque setting will be a higher amount than what is being applied to the nut/bolt.
Some torque wrenches have a clutch system that prevents you from tightening something any higher than what you have set it to.
Should I Buy a Torque Screwdriver?
Potentially. It depends on what you need it for. For small jobs, it is possible to use a torque screwdriver which will be potentially more accurate than a ratchet and can reach down into certain spaces where a traditional torque wrench will struggle. However, they are difficult to put any real power through due to the lack of leverage. If you are tightening anything tighter than a few ft/lbs, you’re going to need a wrench instead.
Keeping Torque Wrenches Calibrated
When click-type torque wrenches are not being used, most must be slackened off to their lowest possible torque setting. Failure to do this results in the torque wrench falling out of calibration, meaning that it will not give accurate results. Unless you check this, there is no way to tell.
There are several ways you can check and calibrate your wrench, with many different methods available. A quick Google search will show you this. We would recommend, however, reading the manual that comes with the wrench, because this should tell you what the manufacturer recommends in this regard, and it is always best to follow their advice.
To look after your torque wrench, you should take extra care with it. They are precision instruments and dropping it can make it lose calibration. Most companies recommend this calibration should be done about every 5000 uses or 1 year.
The regulations for the accuracy of torque wrenches can be found in the international standard DIN-ISO-6789, which refers to accuracy as “maximum permissible deviation”.
What to Think About When Buying a Torque Wrench
When buying a torque wrench, you should think about what you need it for, and that’s all it really comes down to. The best torque wrench for you will probably be different to someone else. Price is always a difficult one with tools – a very low price may appear good, but you might end up having something that doesn’t work and needs to be replaced after one use – however, you also may end up paying extortionate amounts for something which also doesn’t work.
Different Square Drive Sizes
So what do you need it for? These precision instruments come with 3 main sizes of square drive available, which will cover pretty much every task you might need to do on your car at home. These are 1/4-inch, 3/8-inch, and 1/2-inch.
You would need a 1/2-inch drive for bigger jobs such as when reattaching wheels or suspension parts. These are well known and can be put to good use for a range of different tasks. You would use a torque wrench with a 3/8-inch drive would come in more useful for middle-weighted tasks such as changing the spark plugs and gaskets, and a 1/4-inch drive is more likely to be used on very small screws or the occasional gasket.
Your torque wrench must also obviously be accurate. If not, then you may as well just use a normal wrench, and your money will have been wasted.
All torque wrenches should be accurate to at least +/- 6%, with the best ones accurate to 3 or 4%. You can see that even with today’s technology, this is not the most precise reading possible, but it is currently just about the best we can come up with. When purchasing a torque wrench, it should come with a certificate of calibration – always check this.
Another factor to consider is how easy the measure is to read. It may seem obvious, but some measures are much easier to see than others. For example, a digital display shows exactly what amount of torque you are on, whereas other scales and dials can be somewhat difficult to see.
Another factor to consider would be the range of the torque wrench. In general, as touched upon above, the smaller the square drive, the lower the torque range it can reach. Some torque wrenches will have a wider torque range than others – this is always worth bearing in mind when you buy one, because the larger the torque range, the more potentially use you might get from it in the future. However, it’s worth noting that to compromise on accuracy for torque range is not a good idea.
The bottom line is: always make sure that your torque wrench can do the job you need it for well. That will be the best product for you.
That pretty much sums up what you need to know when purchasing a torque wrench. We hope this buyer’s guide has been useful to you. Happy torqueing.
