Whether you’re a professional tradesperson or a keen D.I.Y.-er, you will be aware that man is only as good as his tools. When it comes to assembling safe, long-lasting products, precision is key and getting the torque wrong can greatly affect the quality of your work.
In a Hurry? Here’s Our Top Choice:
This sturdy, precise torque wrench provides all the important functions of a great product, but its adapter, reducer and extension bar set it apart as a great all-around torque wrench solution.
It is likely for this reason that you are looking to purchase a torque wrench, but not sure where to start with the many different options, sizes, and settings available on the market. To help you make sense of which product is right for you, we’ve put together a simple guide to explain the numbers and simplify the facts.
Our Top 5 Torque Wrenches
If you haven’t come across a torque wrench before, then the idea is fairly simple; a scale, usually found at the bottom of the wrench, allows you to preset the desired torque (rotational force) you would like to apply to a nut or a bolt. When the desired setting is reached by the wrench, it will alert you to stop turning, usually through a click sound and vibration.
Torque wrenches come in a range of different options, despite essentially all doing the same thing. The best torque wrench option for you will depend on several things, including the size of the drive socket you require and the amount of torque you need to apply.
The length of the torque wrench’s handle may be of consideration and whether or not you require the wrench to be used in both directions, for which your torque wrench will need a reversible ratchet.
A good quality torque wrench will come with guaranteed calibration parameters to avoid errors and the settings dial should be clear and easy to read. Some products on the market even offer an LCD screen to show the settings, which allows you to work in low light levels.
So if you’re searching for the best torque wrench, then look no further than our handy guide below, with our five best product picks for you.

How to Choose the Right Torque Wrench for Your Needs
Have reversible ratchets got you in a spin? Here’s our simple breakdown guide of the key features of any torque wrench product.
Fastening Size
One of the most fundamental considerations when purchasing a torque wrench is the size of the fastening that it needs to work with. Drive sizes usually come in 1/4 inch, 3/8 inch or 1/2 inch, however, adapters and reducers are available to make your wrench multi-functional.
Torque Measurement
To use a torque wrench accurately, you will need to know the required torque that you wish to apply to the fastening. This can usually be found on information supplied by the fastening manufacturer. The measurement of torque is likely to be supplied in either foot-pound (ft.-lb.) or in Newton meters (Nm). Most torque wrenches have a scale to measure both metrics.
Torque Range
Once you have established the amount of torque that is required, you will need to verify that this amount is within the range of your torque wrench. Each wrench has its own range, meaning that you may need multiple wrenches for particularly high or low torque levels.
Drive Direction
The head of the wrench, the ratchet, drives the torque force in one direction. If your torque wrench has a reversible ratchet, then this means that the wrench can drive in both clockwise and anti-clockwise directions. However, most torque wrenches can only measure preset torque levels in the clockwise direction.
Calibration
For the best accuracy, your wrench should be pre-calibrated and provide a certificate with a guarantee of accuracy range. The industry standard is +/- 4% accuracy, however, some products may improve upon this further.
Alert System
When the preset torque requirement has been met, a torque wrench will alert you to stop applying force. Manual wrenches usually do this by a loud click, which can be heard and felt in the handle of the wrench. More advanced torque wrenches may emit a noise or flash a light instead.
Weight
The weight of torque wrenches generally varies, however, the heavier the wrench then the more strain will be applied to your wrist. If you have weak wrists, you may prefer a lighter option.
Length
The length of the wrench will affect the ease at which you can work. If you want to tighten difficult to reach nuts and bolts, then a longer handle will be beneficial. However, if you’re working at close range, then a smaller handle will be easier to manage and reduce effort to turn the wrench.
Final Thoughts
Once you have a clear understanding of the above features and considerations, then choosing the right torque wrench for you should be a piece of cake. All of the above products come highly reviewed and recommended and for this reason, they have made it to our top five torque wrench list.
