DURATECH Extra Long Anti-Slip Flex-Head Ratcheting Wrench Set, Double Box End Wrench Set, 6-Piece, Metric 8-19mm, CR-V Steel, with Pouch

I bought the upgraded ones with the non rounding feature. I used them to change GMC brakes. The caliper mounting brackets were on really tight like a gorilla last tightened them down. I had to put all my might on the 19mm wrench. I was worried it would brake or bend at the hinge but it didn’t. The head of the bolt did round a bit but the non rounding feature of the wrench didn’t let it go to the point where head was fully damaged. The bolt came out but was jammed in the wrench. I had to put it in my vise and use a punch and hammer to knock the bolt out which worked fine and no damage to the chrome wrench. I did wrap it in a rag to prevent marring. Something to watch out for, when I went to reinstall the bolt I reversed the wrench to tighten. I got to the point where torque was beginning to be applied. The minimally rounded head of the bolt slipped into the non slip teeth of the wrench and the bolt was now jammed again in the wrenches grasp. I don’t blame the manufacturer, this is a caveat of the design. I had to use a flat head screw driver and hammer to dislodge the stuck wrench this time I just gave it a shot or two and it came loose. Left a small mark on the wrench but it’s fine it’s a wrench. Finished applying the rest of the torque with a socket wrench. Overall, Buy them, they are nice. I like how long they are giving plenty of leverage. The pivot head is convenient for tough to reach bolts. The chrome finish is quality and the roll up case will help keep them organized. Good addition to the tool box.

Extra long flex head box ratcheting wrenches are really handy in way more applications than you would think until you have them. They've made a huge difference when doing front end/steering/suspension work. I will readily admit that I have used these to break stubborn and rusted bolts (best practice is to use a regular box end or breaker bar to break the nut free, then switch to the ratcheting) and they are still holding up perfectly fine. The 6 point non-slip heads have nice tight tolerances and have not marred any fasteners I've used them on. Overall fit and finish is better than I expected at this price point. Flex heads have some lateral slip in the pinned joints, but the pins can be tightened. All the ratcheting heads were excellent in terms of smoothness and back drag, except the 17mm for some reason was very stiff and almost "crunchy". Let it take a bath in automatic transmission fluid over a weekend, worked the mechanism a bit, and she's great now. Probably a little swarf left over from manufacturing binding up in the pawls or something, at this price point I consider slight QC issues to be perfectly acceptable. These are great wrenches for DIY and home-gamers, and if you're a professional tech just starting out these would serve you fine until you can afford a set of Mountains or comparable tool truck set. These are FANTASTIC to have in a junkyard tool kit in particular.

So glad I found and purchased this set. Super awesome wrench set that truly locks down on bolts and does not slip, rounding the bolt head. Absolutely awesome and easy to use , sleek design, with the faux gold color on the inside of the heads, down to the engraving. Length is great, unless of course a shorter wrench is needed.
