Suggestions for a torque wrench
Does anyone have a suggestion as to which torque wrench to buy? Best value? I'm looking at (probably) 1/2-inch drive, 20-150 ft. lbs. Is Sears Craftman OK? This will be for general use on my 'Vette, including wheel lug nuts, drain plugs, brake work, etc. Thanks in advance for any suggestions.

Sears Craftsman clicker should work fine for your needs. Can usually be purchased on sale for something like $69-, if memory serves me correctly. Remember to return setting to -0- when not in use. There are better torque wrenches, but more expensive.

If you are truly concerned about the torque you are applying, have your torque wrench calibrated. And no, this is not a sales pitch even though I do calibration for a living.
Most Craftsman torque wrenches have a tolerance of 4% of full scale. So at an applied 40 Ft/lbs on a 150ft/lb wrench, you could actually be applying 46ft/lbs and still be in tolerance.
Unfortunately, the Craftsman/Kobalt/Husky wrenches that you buy at the local retailers are often outside of their tolerance.(Even new!)
That being said, a new torque wrench(any brand) will most likely give you a better point of reference that a socket set and a "tight enough" mentality and will probably be good enough for your application.
It just depends how concerned you are about your torque. Joe Gibbs Racing sends us their torque wrenches for calibration, but they are probably a bit more concerned about their torque tolerances on their cars than you and I !
In my experience, Snap-on/CDI torque wrenches are among the best....but they also cost a lot more. They typically are 3% of full scale and are rarely out of tolerance if not right on the money.
You get what you pay for.

I've got three SEARS click torque wrenches and one old school SEARS beam/pointer torque wrench. They're perfectly fine for the average DIY owner. Don't abuse them (use as a breaker bar) and always crank them back down when not in use.
If you're doing lots of automotive work, engine building, etc, then a more expensive SNAP-ON or MATCO might be considered.

Sears has them on sale right now for $59.99 each, Craftsman Club members.
I own one Sears and two from Harbor Freight. I have a 1/4 and 1/2 from Harbor Freight. The ones I got from HF were around $20 each and they are calibrated within +/- 4% as well.

You can check your own percentage of error for your torque wrench. Since your are measuring foot/lbs, measure 12" back from the socket, attach 50 lbs of weight at that point and then find how much torque is need to just click at that point. I have 4 torque wrenchs, 3/8, 2 clickers and a beam. Suprisingly the beam is the most accurate every time. Anyway I measure them twice a year and they vary slightly each time. I put the wrench in a vice and level it for each test.

Question. If the tolerance is 4% of full scale which is 6 lbs in this case, that would not necessarily mean it’s off 6lbs across the entire range would it? I would think it would be closer to 3lbs at the 75lb setting.

4% of 100 = 4
4% of 50 = 2
4% 0f 25 = 1
4% of 200 = 8
4% of 150 = 6
HOWEVER - The the MOST accurate percentage is usually found at FULL SCALE. So at 25ft-lbs the accuracy may only be say 5%.

Harbor Freight.. I have 3 of them in all sizes.. Work awesome for the very few times you need one..
More money does not always equal better.. As long as it's calibrated correctly.. you are golden.. Less thna $50 for all 3 and very well made..

I have owned several. The cheaper ones the lock mechanism is not very good and before you know it you have changed the torque setting and question ??? When did I do That??? The craftmans seems to work ok but I invested in a Snap On and consider it worth every penny. When you reach the set torque it has a very distinctive click and a lock mechanism that you can't change without an planed effort. If you work on C5's you will need an inch pound wrench also IMHO
