Review on TEKTON TRQ21101 1/4 Inch Drive Dual-Direction Click Torque Wrench (10-150 in.-lb.) by Omar Austin

I opened the zippered hard case and was immediately impressed by the feel, markings, handling of the micrometer setting and the ease of use of the ratchet. Mechanism. Not a big fan of quick release knobs on the ratchet as it requires a hollow drive wheel that releases the drive connector. You could remove it from the design and it wouldn't matter. Proper maintenance of the ball bearing with a drop of penetrating oil periodically will prevent the need to remove the seats. However, this is not a major concern with a torque wrench that is not expected to break stuck fasteners. The markings are very easy to read, as is the torque setting. This wrench has a novelty slip ring that you pull down to unlock the handle and rotate in 1 inch-pound increments. I've never come across a half inch-pound spec that requires a wrench that covers a 10 to 150 inch-pound range. If I did, I'd just round up or down and be done with it. Even at a minimum of 10 in-lbs, 0.5 in-lbs is 5%, which is close to wrench specs and close enough for practical purposes. Those working on stealth composite aircraft, spacecraft, and nuclear weapons that require 1% or better accuracy will not use Tekton to begin with. Its function has been tested using a 1/4" drive breaker with a 1/4" octagon socket (for nuts, bolts and square head screws). The "click" is easily felt throughout the range and is unmistakable, even at 10 inches per pound. Haven't noticed any difference either forwards or backwards. There is a common misconception that the "click" is meant to be heard. Although audible depending on the ambient noise level (some stores are noisy due to machinery and fans), it can be felt by hand turning a wrench as a roller bearing rolls over a stationary roller bearing on a carrier. on a heavy spring that causes a "break" of about 10 degrees when the key is turned. Release the pressure on the handle and it will lock into place. The fabric-covered, semi-rigid, zippered case differs from the traditional inflated cases that most wrenches are currently supplied with. He won't put up with the bumps and bumps bouncing around in the box of the other steel tools he's exposed to. I certainly don't store or carry torque wrenches that way. These are (semi) precision gauges, not breakers or sliding T-handles, and should be properly protected. Some may disagree with the case and its strength compared to blow molding. I do not know. Over the last 45+ years I have edited, used and owned many brands of instruments including high quality Snap-On, SK and Proto which I still own and use. This is an impressive torque wrench, especially for the price. It's easy to spend 2-3x or more for a 1/4-inch micron bidirectional clicker and get little, if anything, useful for significantly more money. to break stuck or rusted fasteners, especially bi-directional ones like this one. This can easily upset the calibration and permanently damage the snap mechanism inside the key (even on a unidirectional one). Proper use requires slow and firm rotation when tightening the fastener until the wrench "breaks" approximately 10 degrees, indicating the set torque has been reached. This is not a race team competition. Achieving the correct torque with reliable and repeatable torque is a deliberately methodical process - the wrench only turns in the middle of its grip. It may seem counterintuitive, but clamping over the handle or worse, using a 'rogue pipe' to increase wrench length will not accurately tighten the fastener. I've seen this demonstrated on a torque calibration machine and the reason lies in the construction of the click button and its internal beam mechanism. They all use the same mechanical concept inside.
