To select the torque wrenches featured in this buyers guide, our team first combed through dozens of resources such as DIY mechanic and auto enthusiast forums, manufacturer and maintenance-specific websites, instruction manuals from manufacturers, and reviews from online retailers. We pay particularly close attention to quality reviews and recommendations that highlight the quality of warranties, customer service support, build quality, materials, and overall reliability.
We also factored in the quantity and quality of online retailer reviews from websites such as Amazon, RealTruck, Advance Auto Parts, and more. We looked at factors such as standout customer reviews, prices, meaningful superlatives, and discount shipping eligibility.
Our product testing team ordered the wrenches that best met these standards. A team member tested each torque wrench, taking note of accuracy, ease of use, and quality of construction (durability). Each torque wrench was given a rating out of 5 stars based on these criteria.
Accuracy is vital for a quality torque wrench. The best torque wrenches can be accurate to 1.0 lb-ft of torque. We gave the highest accuracy scores to those torque wrenches that most closely matched the readout of our torque adapter.
Ease Of Use
Our ease of use score is based on several factors. How simple is it to set the desired torque and in what increments? Handle comfort and features like a flexible head also contributed to our ease of use rating.
Our durability score is based on our experience with each torque wrench as well as the collective consensus of verified Amazon reviews. Torque wrenches built to last, featuring solid construction, and said to be long-lasting according to online reviews scored best in this category.
Torque Wrench Testing Process
We tested each of our recommended torque wrenches by tightening the lug nuts on a 2017 Ford Fusion. We set each torque wrench to a specific rating and compared this measurement to the readout given by the ACDelco ARM-602, a digital torque adapter guaranteed by an ISO 6789 certificate of calibration.
