but for how long? I have had bad luck with cheap tools. I personally like craftsman overall. Good quality at a good priceI bought mine from a Tool store then tested its accuracy against a High dollar Snap on one I use at work. The one I bought from harbour freight was just as accurate best 50$ I ever bought.
I can't complain about the.accuracy of my Harbor Freight torque wrench. some of the tools they sell there are actually very good quality. several years ago I bought a floor nailer for installing hardwood floor and I have put a lot of hardwood down with thatfloor nailer and never had a problem with it. yet it was half the price of a floor nailer anywhere elseHF makes a digital torque adapter that is very accurate--a claimed ± 2.0%, however my dead weight testing found it to be better than that. This is more accurate than any clicker you can buy.
I do not use it as a torquing tool, however I do use it as a standard against which I calibrate the various clickers and digital wrenches I have. FWIW I have also found the HF torque wrenches to be as accurate as any others...
I have a HF in lbs TW and after doing a dead weight test it was off by 18 in lbsMy step-son and I were discussing this just yesterday. While Snap-On, MAC, an a very few others are still top-of-the-line (in quality and price), Craftsman tools are a mere shadow of what they once were and overpriced to boot. Harbor Freight's wrenches, if you avoid the real cheap happy-homeowner crap, as good as or better than Craftsman--at 2/3 to 1/2 the price.
And they are all, except some (not all) of the Snap-On, etc line, made in China now--so much as it pains me I have decided to be "over that..."
18 lb-in at what setting (just curious, at 7% error it sounds as though you were near the top of its range)?I have a HF in lbs TW and after doing a dead weight test it was off by 18 in lbs
My Great Neck Ft LB TW was balls on.
That being said now that I know its about 7% off its still usable but its something that should be done prior to using it that way nothing would be under torqued, also for paying 10.00 for the HF wrench I guess I cant complain.
thats at 260 in-lbs, i did not know about the calibration screw nice info.18 lb-in at what setting (just curious, at 7% error it sounds as though you were near the top of its range)?
There is a small port on the wrench body through which you can calibrate the HF wrench, pull off the plastic cap and there is a calibration screw:
"Clicker" torque wrenches, except the beam type, need to be calibrated at least once every two years--more frequently if often used. It is also important to back off the torque setting after using the wrench. I back it off all the way and then tighten the adjustment just up until you can start to feel resistance--this will leave the torque mechanism engaged, but the spring minimally loaded.
i'm sorry it was actually at 126 in-lbs , 11lb weight x 11.5in, and its the 20-200 inch-lb wrench which would put it right at the 70% range of the wrenches range7% error at either extreme of a clicker wrench's range is not uncommon, Snap-On only guarantees ± 4.0% for their clickers. MAC says ± 3.0%.
It is best to select a torque wrench so that the desired torque will fall within 25% to 80% of its full range. I have not mapped one in years (like 30 maybe) however back then I found accuracy at the extremes to be off by as much as to 30%, even more...
