No I haven’t. Two wrenches that I use the most come with calibration certificate traceable back to NIST standard. I pay special care when using all my torque wrenches so the setting is brought back to 0 when not in use. This type of work does not require very accurate tool anyway and if you take care of the tool, it can really go long way without re-calibration. I also always buy torque wrenches brand new since you never know how good care POs were taking. Many times you can see techs dropping them on floor and not resetting to 0 basically ever which is bad for spring and overall accuracy. If the tool is used for applications that require extreme accuracy, then often calibration is necessary and those are different type of torque wrenches used for those applications. Hope this makes sense. Thanks for watching!
Have you ever tested your torque wrenches for accuracy ?
