After reading that a bolt stripped threads during torquing with a torque wrench I just wanted to remind everyone that a calibrated tool may not keep its calibration forever. Having been in aircraft maintenance my entire working career these things stick with you. The helicopter company I worked for, for 39 years, had all torque wrenches checked once a year by the inspection dept. Granted, a full time mechanic turning wrenches will develop a natural feel for the correct torque in most cases. But, a backyard mechanic may not.
