As cheap as they are, I’m a little paranoid. After setting them, I always clamp the drive end into a bench vise and take it to the click to make sure it feels right. With spark plugs, were the clicker to fail, one could do a lot of damage waiting for a click that never came.

That said, I’m on my third set and no problems to date.


Folks, this is sage advice, thanks Eddie. I bought Harbor Freight torque wrenches and found the 3/8 drive was bad out of the box. Read this and tested it and the 1/4 and found them both bad. Replaced them and from now on will “Bench” test them prior to use. If I get another bad one, I’ll spend the money on a digital one.
