The Buyer’s Guide

Torque range

If you need the tool for the frequent use and versatile fasteners, it is worth choosing several instruments with different ranges. It is essential to know what tightening torque range will be relevant for your car repair jobs.

A range of up to 20 to 150 Nm is enough for small jobs. If you use a torque wrench more frequently – the range should be about 100-700 Nm. If you apply the force of 80 Nm, the tool should have the range from 20 to 150 Nm.

The square head drive size

The size of the square head drive is also crucial. It is measured in inches. There are 1/4-inch, 3/8-inch, 1/2-inch, 3/4-inch, 1-inch, etc. Check the size of the fasteners you need to tighten. Only then you should choose the corresponding square head drive size.


On the terms of accuracy, you should avoid any basic beam instruments because they are least accurate. Then click torque wrenches come and only then the most accurate digital instrument. Most U.S. tools follow the generally accepted measurement standards when the applied force is defined in Newton meters and inches-pounds (foot-pounds). The pre-calibration can be a good sign for people who seek the tool to use out of the box.

Ergonomic design

The leading manufacturers make sure that the ergonomic design of their tools is performed at the highest level. But there are the wrenches that are too long or too short and that’s why they may cover the fastener while you are tightening it. Avoid such tools at any cost. Also, stay away from the tools with too small markings on the handle. If you use torque wrenches at night, make sure to invest in a digital instrument with an LCD screen for better visibility. Or, at least choose a click wrench with large engraved markings.

The direction of torque measurement

It’s worthwhile to understand beforehand in which direction the wrench can measure the torque. Most instruments are adapted for right-handed people and therefore have a corresponding clockwise direction. But some people are used to working with the left hand only and that is when you need to choose a bi-directional tool that can rotate in both directions.


Typically, at least one interchangeable pivot head comes with a wrench. Interchangeable heads produced by the same manufacturer are more preferable than interchangeable heads purchased in different places and made by different brands. But if you initially bought a cheap wrench, you should not rely on its high quality, including the head.

A storage case

A convenient, relatively lightweight and capacious storage case can help to keep the torque wrench and its attachments organized and safe from moisture. If the manufacturer sells the tools in a special case, offering space for additional components, this is a great benefit.

What factors did I consider during my tests:

  • Accuracy – do not but cheap and inaccurate wrenches. Opt for a certified tool that is accurate from 30% to 80%. Also, the range must be good enough for small jobs;
  • Quality – another thing to look for is a tool with a solid body made of steel alloy. They will serve much longer;

I also like to add that markings also matter. If you have poor eyesight like me you will need a tool with printed markings that are more visible. Engraved markings last longer, on the other hand.

I sincerely believe that my top 3 will be the best picks for people who need a durable torque wrench with multiple measurements, peak and trace modes. I recommend investing money in a good tool if you repair cars, bikes, and bicycles on a daily occasion. That should be chromium and vanadium steel alloy, with a highly-accurate range. I also give tips on where to buy such top-notch tools at a low price.

My top 3 of the best 3/8 torque wrenches in the U.S. market:

  • TEKTON 24330 – I really like this tool for being very accurate, with the range of 13.6-108.5 Nm;
  • EPAuto offers a 24-tooth gear for the length of 14-1/2″;
  • TACKLIFE has a very good torque range – 13.6-108.5 Nm;

Final thoughts

Do you still have the problems of choosing 3/8 in. wrenches? Then check this review of some best instruments and make a choice. The most important factor to consider – accuracy. Nevertheless, also, select the wrench made of durable materials and long-lasting warranty.

I’m a Matthew Johnson, and I’m a motor mechanic. I like my profession and every day I use many tools, but a torque wrench is most useful of them. I’m going to write about my experience of using different torque wrenches and share with you.
