I use the Husky hand tools and do use their torque wrench. I was worried about it at first, took it to work with me and had the motor pool (Army) guys run it on their calibration, it came out to be ~1.5 lbs, too low, so I set it 1lb over recommended tq and call it even. I have also tested other off the shelf wrenches this way and found many are about the same variance. Exception was my old Snap-On someone decided they needed more than I did, smashed my truck window and took it. Anyway, that one came out <.25lbs off. so it was good.
For the $ I havent found many hand tools out there I like the ergonomics of better then the husky. And havent had a failure yet. Of course, these LS1 dont require the same torque as the Olds BB do either.
The QC on their Tq wrenches may suck, just seen where above stated it was off a lot more than mine....maybe I got lucky, you unlucky or thats just the lacking of QC.
