Pro tip: a 20 year A&P at a hangar in Wichita showed me the torque wrench trick I never learned in school
Honestly I always just clicked the wrench and moved on, but he made me back the setting off to zero after every single use. Two years later my 1/2 inch Snap-on still holds calibration dead on, and the shop's loaners are all over the map. Any of you guys actually store yours wound down, or am I the only one who got taught this late?
