I used to have mine checked yearly because I used them so much. I'm surprised how off they can get. I actually wore a torque wrench to the point it was no longer able to be calibrated.

For wheels I just told the techs to buy a cheap harbor freights and compared the torque value with a known good one every once in a while. No need to wear out a expensive torque wrench on lug nuts.
