Lost on which types of torque wrenches to purchase? It doesn’t have to be difficult to find the right torch wrench for your project. We’re going to take you through our picks for the most accurate torch wrench so you don’t have to do the research yourself.

Accuracy Techniques

Always remember when it comes to making sure torque wrenches are accurate, you need to do some of the work to maximum accuracy yourself. The factory calibration alone isn’t enough. Making sure your torque wrench is properly calibrated is important and your technique can have a bigger effect on accuracy. The wrench’s own accuracy and calibration isn’t the only factor. Here are a few things to be looking for when maximizing accuracy:

• Make sure you’re looking carefully and not inducing your own error when setting the torque wrench’s calibration. This is something you’re going to need to set with your own eyes. It’s easy to get it even a couple digits off, especially if you are looking at the scale at an angle.

• Watch your technique when it comes to turning any type of torque wrench, whether a click torque wrench or drive torque wrench. Make sure you’re turning it slowly, smoothly, and steadily and that you stop when you feel or hear the click if using a click-type torque wrench. If you continue to tighten after you have heard the click, you’re setting yourself up for failure because you have applied an extra load to your clamping which could result in broken or stressed bolts. If you do not take care to slowly swing your torque, you could very well accidentally swing past the click.

• Be aware of the physical conditions that your torque needs to measure accurately. For example, some specifications require a cool, dry fastener but it’s possible that your fastener is hot or greasy. In this case, you are knowingly risking inaccurate measurements, although you may still come close. Generally, you do not want to base your end results on “close” or expect close to be considered a safe standard for your project – the results will be adequate at best. Keep in mind that over-torquing nearly always results in broken or stressed parts or early deterioration while under-torquing can result in loose parts. Loose parts are just as dangerous as they can fail or come apart at any given time.

• Be mindful that you are applying pressure to the wrench’s handle and not to the body of the wrench. A torque wrench measures force just below its head, at the pivot point. It is specifically designed and calibrated so that, by applying force to the handle alone, the force adds up to the amount of torque shown on its scale.
