How the hell do you know if these things work??? I THOUGHT I set it on 25 ft/lbs, tried to break loose a lug nut, and it snapped the extension! I bought it thru e-bay, and I guess a mechanic don't need instructions on how to operate them, still I wish something came with it to give me a clue. Anyway, I don't want to put it on something that HAS to be torqued, just to snap a bolt because it's set wrong. Any time and info is greatly appreciated.

Click types are very inaccurate at low torque values. At 30 lbs ft or less, I use my beam type TW, because a click type is too vague feeling at lower settings.

You can get them calibrated, usually by sending them to the manufacturer, but most people I know just compare them to another known good TW. It actually isn't all as crucial as you might think, you'll notice the range on torque specs are usually fairly wide. What is more important usually is that the fasteners all have a uniform torque to allow an even loading of a precision surface.

PS, if you saw how seldom some dealership techs use their torque wrenches, it would scare the hell out of you.

It may not be bad, Craftsman and Snap-On wrenches are the same way. Crank it up to 85 lbs ft and tighten your lug nuts, I bet it will feel fine.

Just curious,

Why would you be using a calibrated tool like a torque wrench as a breaker handle to begin with?

I never use my Torque Wrenches at home or at work for anything beyond what they are intended for..which is torquing bolts...not breaking torque.

FYI...in my line of work , all torque wrenches are sent out every 6 months for re-calibration...and even sooner if they happen to get dropped by accident.

My friendly suggestion to any and all..is to use these wrenches only for what they are intended for...breaker bars or breaker handles are cheap as opposed to breaking things or sending them out for re-calibration

I understand that. This was intended to see if it really did what it was supposed to. That's why I set it at such a low torque, I KNEW it should click way before it would ever break it loose. Well, the extension snapped before either of the other 2. Not a mechanic, so my use of these tools are limited, and I pretty much get all the info on the matter from you guys. But, if the wrench is good, then it should have "clicked" before the xtnsion broke, right??? I'm gonna take a real good look at it tonite and see if it's operator failure. Better chance of that, than the wrench being bad . Thanks for the replies guys.

William,

Yes , a good Torque Wrench should have clicked if the item being torqued was at the assigned value you had set on the wrench. The operative phrase being "Being Torqued"..not breaking torque.

I have never used one to break torque..as I have too much respect for my A&P License and my personal tools...I assume the click may not apply in reversal of torque application..as that is not its designed intent.

I do suggest this...breaker bars and breaker handles for breaking high torque items like lugs...and only use sockets and extensions that are rated for impact gun purposes when using these items.

Follow these simple practices...and your trips to the tool store for replacements will be far fewer..and you just might save a knuckle or two from a standard socket walling out or an extension breaking under load.

Thank you for the knowledge Sir, and I will use it to the best of my ability from now on. I was taught by a mechanic years ago, and he was not happy, that a torque wrench is NOT a breaker bar. I was under the assumption that it would work EITHER way, but I see NOW that it would not. Like I said, it's operator failure, as usual. Still gonna get more fimiliar with it, got some motor things to change that I want to be sure are done right the first time . Thanks again for the time and knowledge. I love learning something new.

Most don't click very loud at low torque readings.

William,

No problem my friend....hell , I wish I had a dollar for everything that I had to learn the hard way , I can assure you if I did...I wouldn't be wrenching on commercial jets for someone else now. (LOL)

Regarding the engine you plan to work..do a lot of reading on the subject...find a machine shop if you can , that won't mind you observing them...those things have helped me beyond belief.

Also...I for one , do not use Air Tools for tearing down engines or assembly. The educated feel between the wrench and the hand can sometimes prevent breaking off a factory spec bolt or rounding off a bolt head that has been in place for more years than we would care to calculate at times.

I'm tearing down a 351C at present...and I've done a number of Windsors in the past..but by far the worst I've ever encountered for frozen bolts was a 2.3L Turbo out of a 1988 T-Bird Turbo Coupe

I believe in a liberal use of a product called KROIL..I like it better than WD40 or Liquid Wrench...it is advertised as the Oil that Creeps and it works well. Just don't use it on items that can't be completely cleaned afterwards...or torque and tightness will be hampered along the way Lug Nuts being a great example.
