* In the Air Farce we were supposed to click the break type torque wrench
three times at the lowest setting before using it. This was supposed to
spread the lubrication inside.

Having said that, in my first shop in the USAF we calibrated torque
wrenches so I may be a tad biased. The machine we used was huge and
probably weighed close to a ton. Torque wrenches in the USAF are
periodically calibrated, I forget the cycle, and taken in for calibration
if dropped or abused.

system that didn't even require a torque wrench. (PMEL calibrated, of

Simply "strip" it and back off one half turn. Farm boys from Georgia taught
me that.

Yeah, but ya gotta know the difference between metric and SAE torque.

SAE = 1 3/4 grunts
Metric = Gutentieght
