Torque wrench

I own 3 TWs, a 1/2" drive for torquing lug nuts, a 3/8" drive for most other things like suspension and brakes, and a 1/4" drive inch-pound one for the gentler stuff like the water pump where you don't want to crush a gasket.

For the large one (1/2" drive) I bought a Craftsman, new on sale. I bought the other two (used Snap-on's) from tool vendors at a local flea market and had them calibrated (checked really - both were within spec) through a friend who owns a shop. You can get some good used ones at really cheap prices if you keep your eyes open (flea markets, craigslist, and ebay). I'd recommend buying a good used one that's been taken care of over buying a new cheap HF one.

My recommendations:

1. The time to be looking for a torque wrench is now, not when you need it for a repair. Keep your eyes open for a quality used one and take your time. Although you might use it only once a year, you want to buy a good quality torque wrench because the good ones will last forever. I've had my 3/8 drive one for over 30 years!

2. Store your torque wrenches dialed all the way back to zero (or as low as they go) and store them in their cases. This will help them hold calibration.

This entire post, along with other just stated completely sums up my prospective.


Right now I think I want the AC Delco ARM601-4 1/2" Digital Torque Wrench (4-99 ft-lbs)

According to the reviews its very accurate and repeatable within what I believe to be its sweet spot range (from about 10-80). To me this is effectively a 3/8" TW in a 1/2" body. I would not use it for lug nuts being that require about 96ft/lbs which would be the upper range where I would avoid using it.

Again I agree that having multiples TW's is the best way to go. In my case, I'd probably pick up a relatively inexpensive 1/2" TW for the lug nuts and either a 1/4" or a 3/8" in for the lower range where the primary AC Delco would not fit (physically that is).

Is this sound judgment and strategy? Again I need this for oil changes, brakes and who knows what else is in store, but those are the big two.

That sounds like a good plan except lose the "probably". Especially when it comes to wheel lugs. Even though I can't afford new shoes, I found a way to get a 1/2" 0-150 lb torque wrench.
