If you can do without your wrench, send it here: http://anglerepair.com/calibration/

Those MAC/SnapOn trucks also have universal calibration testers on them as well.

Or just Google for torque wrench calibration... like I did in my area and I got a place that is 10 minutes from my house: http://www.mohawkltd.com/

 

thanks for the tips on torque wrench, It is a harbor freight one.

 

It can still be calibrated.

I admit, I got a HF (Pittsburg) and I had it calibrated. Works just fine for home/farm/light shop use.

I also got some name brand ones too. They are all close enough for me -- I'm not working on aerospace tech in my shop... haha
