I've got a craftsman clic type that has served me well. Â I wanted to get it calibrated once, I live in West Michigan, called around the Grand Rapids area to three or four places that do weights/measures/tooling calibrations and the price for calibration was almost THREE TIMES what I paid for the tool.
Each service explained that they are unable to provide a service that is any less than the completely full roster of checks and certifications. Â
"Can't you just do a simple bench test and reset? Â The tool itself isn't even mechanically accurate enough to benefit from the degree of precision you describe"
No, we cannot do that. Â There are liability and certification issues.
"Can you suggest anyone to recalibrate this "consumer grade" tool for me for a reasonable price?"
No we can't.
So where did you get guys get your wrenchs calibrated? Â Or did you do it yourself?
I've seen versions of these....

These often cost considerably less than the one time calibration I was referring to above.  These "toolbox" calibration tools can be used on-their-own as primary torque wrenches with a standard socket wrench and have an accuracy similar to my wrench (just off the top of my head it's about 3 percent or so). As your primary torque tool the most obvious problem is the length that is now pretty obstructive for any tight situations at all.  They can also be used to calibrate your existing wrench, but  using a such a similarly (in)accurate tool would compound the calibration inaccuracy to six percent possible in a worst case scenario.  Not real good.
