Tonight on GRM LIVE!: Torque Wrench Testing

A torque wrench is an indispensable tool for any shop, so choosing the right torque wrench is an important decision. Tonight live we'll use a torque wrench calibration meter to test out wrenches for every budget from USAG, Sonic, ICON, Kobalt and Harbor Freight. What features will we like the most? Which will be the most accurate? Tune in to find out! Join us live with your questions and comments.

I hate most tire shops and torque wrenches , 

The correct way to use one is to back off the pressure and then pull it down until it clicks !

Seems simple but most tire stores slam the lug nut on with an air wrench and then "check" that it is correct because the torque wrench "clicks"

Problem is it can click at  the number you set or ANY number higher !

So when you have a flat and try to change your own tire you may never get the lug nut off as it can be way over the limit.


Ok , rant over , I am sure you guys understand , tire shops do not :(

So, what was the torque wrench weight?  Did I win?

I've accumulated nine various torque wrenches over the years and these days generally default to the HF digital torque adapter.  It does take some time to figure it out as you can, as JG noted, overtorque if you don't stop when the beep goes constant.  It's also useful for calibrating the mechanical wrenches.

On the other hand, I've had two of the cheap HF click wrenches fail.  A 3/8" wrench took a bolt well into yield before I realized it wasn't working, and I have a 1/2" that reads about 40% high.  HF traded me a new 3/8" wrench, no questions asked.  Still need to see if they'll do the same for the 1/2" but I really don't trust the cheap wrenches any more.
