You gotta explain to folks what it is like to have coal miners & ex-coal miners around. I've never met one that could resist tweaking any adjusment knob they've ever seen and it ain't tight 'till it squeeks & glows red.
American measurements of torque- inch pounds, foot pounds & erks. Erk is the sound the fastener makes as you approach its maximum tensile strength.
Few things are harder to put up with than the annoyance of a good example.
FWIW: I just watched a Journeyman electrician retorque some lugs to well over 30 pounds-feet, with a calibrated (have the paper) pounds-inch torque wrench set to 100 lbs-in. (watched it being set by the UPS tech and verified it). Some people just don't get it. Jim
