Even for a seasoned mechanic, there are parts of the car where relying on intuition isn’t enough. Torque wrenches are perfect for taking the guess work out of tightening bolts and ensuring you conform to the standards set out by the car manufacturer when it was designed.

Torque is a unit of measurement that determines how much pressure is required to turn it, torque is determined by the amount of force used and the distance to the pivot point. But we don’t need to go all sciencey on you because a digital torque wrench will do all of that for you and use it’s electronic sensor to tell you when the correct torque level has been reached.

In this guide, we’ll take you through the best digital torque wrenches available in the UK to help you choose your next tool.

Digital Torque Wrench Buying Guide

Here are the key things to keep in mind when buying a digital torque wrench. If you’re familiar with buying torque wrenches, the concept of buying a digital torque wrench is relatively similar so you can skip straight to the recommendations.


Each torque wrench will have a certain range of accuracy depending upon the electronic sensors inside. Cheap torque wrenches are often not as accurate as more expensive ones, as you’d expect. We recommend a wrench that has an accuracy within 5%. Although some of the wrenches here have an accuracy within 2% which means they are even more precise.

Torque Range

A torque wrench will have a set range within which it will work so you should ensure it’s suitable for the tasks you’ll be doing. Torque is measured in foot-pounds (ft lbs), kilogram-metres (kg-m) or newton-metres (n.m.). We’d typically recommend a torque range of about 20-120 n.m. for an all-round wrench. A spark plug might be at the lower end of this spectrum, whereas head bolts will be at the other end.

Head Size

The head sizes of a torque wrench is really important. For most people, a ½” or 3/8” head will provide the torque range needed and be most suitable for working on most vehicles.

Metric or Imperial

As mentioned earlier, there are various units of measurement for torque. Being from the UK, we try to work in metric units where possible (n.m.) but there are benefits to having both options available. Most digital torque wrenches will cover foot-pounds and newtown-metres, however, don’t take this for granted and be sure to check. Ultimately, this depends on the make of your car and how you like to work.
