Some non-professionals may think that the more you tighten a fastener, the better it’ll hold in place. This is absolutely wrong. Over-torquing a fastener will increase the probability of its fracture in the future if it didn’t already fracture during the tightening.

But how to actually know how much torque you’re applying? That’s when a digital torque wrench comes in handy. In contrast to the traditional wrench, this tool lets you know the exact torque you’re applying in real-time.

That’s why we’ll review the 3 best digital torque wrenches in the market. Shall we begin?

What We Chose for You

We’re going to review each product based on its technical specs in addition to the pros and cons we found in customers’ reviews.

GEARWRENCH 85078 “3/8” Flex Head Electronic Torque Wrench – Our Top Pick

GEARWRENCH 85078 "3/8" Flex Head Electronic Torque Wrench - Our Top Pick

This is one of the most accurate torque wrenches out there. It reads torque in a range of 10-100 ft-lb with +/-2% accuracy in the clockwise direction and +/-3% accuracy in the counter-clockwise direction. For better accessibility in tight spaces, the head can rotate up to 5 degrees.

It works with a pair of AA batteries and reads torque in 5 units: ft-lb, In-lb, Nm, kg-m, and kg-cm. While setting the torque, you can add in increments as small as 0.1 ft-lb, which really makes sure you provide just the right torque.

For a better experience, this wrench provides a triple alert when it reaches the specified torque. These are: a vibrating handle, a buzzer, and a solid LED indicator.

It can also notify you before actually reaching the torque by a percentage of your choice. So if you set the torque to 100 ft-Ib with a notification at 10%, it will alert you at 90 ft-Ib.

The tooth count on this product is 72-tooth, which gives you a fast seamless ratcheting experience.

Considering durability, the grip handle and the metal housing are both resistant to varying oils and solvents, which are abundantly found in most workplaces.

It also comes as 1/2″ drive, with or without the flex angle.

Since we mentioned 3 products from 3 different brands, we’ll refer to them by the brand name for convenience.


GearWrench and CDI both share the same torque range. But GearWrench excels in the accuracy.

ACDelco falls behind in the torque range but holds high accuracy.

ACDelco is the best for your budget. GearWrench is cheaper than CDI but with a small difference.

How Often Should You Calibrate Your Torque Wrench

As a general rule, torque wrenches should be calibrated after 12 months of regular use.

However, if the wrench is subjected to a high workload, extreme temperatures or frequent physical impacts, you’ll need to calibrate it more often.

The Verdict

Our top pick for the best digital torque wrenches is GEARWRENCH 85078 “3/8” Flex Head Electronic Torque Wrench. It has one of the best accuracy levels in the market. The triple alert system and the five torque measurements it reads greatly improve its experience.

The 3/8″ driver size is the most common size you’ll need in your garage, car, etc. If you have other special uses in mind, consider the other sizes of 1/4″ and 1/2″.
