Default Torque Wrench

Quick question: Looking to buy a torque wrench. Do we use a 1/2 or 3/8 wrench? Any suggestions as to a good but reasonably priced wrench?

Sears Craftsman Microtork is a good value. The only problem is you'll end up buying a minimum of two to cover the full range of torques...1/2 drive, 25 ft-lb to 250 ft-lb, and 3/8" drive, 25 in-lb (2 ft-lbs) to 250 in-lb (21 ft-lb). They also sell an intermediate torque wrench that a nice fit if you don't need torques over about 150 ft-lb.

Having a second torque wrench with a narrow scale for in-lbs is a actually a good thing...you are more likely to always get good readings on the low torques, and you not tempted to try driving a tack with a sledge hammer.

I managed to cover the range with 4 torque wrenches, including the tiny little beam wrench down to 5 inch-pounds.

2 is ideal, but if you only get 1, get the 1/2'' drive for the higher torque levels, like lug nuts and brake caliper brackets.

Hey Jack, out of curiosity, have you used that 1/2" drive much at the bottom end of the scale? I wondered if you have confidence in the accuracy of the clicker down low. It seems like it gets pretty mushy to me....

I agree it's less than ideal...calibrated instruments and tools are most accurate near the center of the scale. I have also noticed what you describe.

I have told myself that if the manufacturer extends the scale down to those values, it should be useable there. But, to be honest, I have an old beam torque wrench that I've used to double check the clicker down around 25 ft-lb. Unfortunately, there are a LOT of fasteners on a car that fall right in that torque neighborhood.

The wrench combination I have is a compromise to avoid spending the money for another torque wrench. I'm cheap...I should just spring for that intermediate range torque wrench; if you can only afford one torque wrench, then the intermediate is the way to go.

That's what I use 90% of the time.
