Bests & Worsts Reviews from Amazon

In order to gauge the accuracy of this torque wrench I tested it with an AC/Delco Digital Torque Adapter and compared it with a Snap-on I already owned. The AC/Delco unit was certified to be within 0.3% of actual torque. The Tekton wrench did not come with a certification as mentioned by some, but only had a sticker stating it was "certified." Straight out of the box, the Tekton was wildly inaccurate, but after exercising it a bit, it measured on the outside range of the +/- 4% specification. It generally applied about two to five percent too much torque for the setting, rarely applying too little torque. After using it a while, my observation is that it should be exercised at least five times at 50% of max torque before torquing anything. If it has been sitting overnight, exercise it again. You just have to know this should be done with click type wrenches since it is not mentioned in the operator's manual. Compared to the Snap-on wrench, I would say the Snap-on supplied more accurate and consistent results, without the need for exercising it as frequently. Of course, the Snap-on cost about 10 times as much as the Tekton. For the money, I would say it is a pretty good wrench as long as you remember to exercise it before using it each day. Don't expect the spit and polish of a Snap-on. If you want chrome, shine, and a polished finish, you will need to drop a few more dollars.
