Yeah so, I needed to apply torque angle or angle torque to my hot wife’s 06 Malibu cylinder head, camshaft, crankshaft, etc. bolts. Amateur mechanic on best day but a Hanes manual and the right tools have helped me not tear anything up. Yet…Typically, this was a little more than I would spend for an automotive repair tool but I tried a cheaper dial adapter type and wasn’t successful. I’m positive it was operator error even after giving several goes at it. This is my 1st tool from AC Delco and I’m very pleased with its performance. The 1st thing I noticed was the quality of the case. Seems durable, well constructed out of quality metal, latches and sturdy handle. Inside the case the wrench has to be removed with some assertion as its surrounded in a comfortable looking cushioned protective mold that prevents any movement while in transit. Although it didn’t come with batteries there is a cut out in the cushion made specifically for battery storage. The wrench was smooth simple to use and big enough to get mean with. Push buttons for selecting type of torque and how much to apply. Digital readout. Has a single short audible beep as u near setting and speeds up to a long beep and vibrates when done. Specs for head bolts were 22 ft. Lbs. plus 155 degrees and I have no idea (other than guesses) why but according to this wrench these 10 are guud-n-tite! Again, I am no mechanic by any definition but this is a badass wrench. Well worth the $. It has many more features I’ll probably never use but for what I needed this worked out great and gave me the confidence that i did it correct according to the Hanes manual, anyway.

Needed a torque wrench that could do angles on bolts after doing a head gasket. This is the best

I like the wrench. I’m building a 6.0 LS for my 63 nova and used a dial gauge first go around. Long story short, I had to pull the crank back out to fix the cam bearings the machine shop got wrong. Going back together with this wrench was fast and easy. This is one wrench I’m keeping around!

I rebuilt a bmw x5 f15 engine with this. It gives accurate measurements.
