I'd be happy to calibrate that wrench for you. Send it to me and I'll create a cal-sheet for it and send it back. Along with repeatability test. Won't take long in my instrumentation lab.




It proves that its doing the same thing it did last time, which is what I am after.

I appreciate the offer, but I am not sure its worth the time and trouble for a $60 wrench...is it?
