Serious question, does anyone else run torque wrenches to the low end of spec on purpose?
Everyone in my shop says you go to the high side of the range, always. Last week I did a flap actuator install on a King Air 200 and hit the bolts at 40 inch pounds instead of pushing toward 50, which is the top of what the book allows. My lead gave me a hard time about it for ten minutes straight, said I was leaving them loose. Here is the thing though, I have pulled fasteners that were run at the top number and found stretched threads and crushed washers more than once, and nobody wants to talk about it. A torque spec is a range for a reason, not a dare to see how tight you can get it. Am I alone here or does anyone else aim low on purpose?

40 inch pounds on a flap actuator is not loose, it's 80 percent of the range. Your lead is the guy who rounds every spec up and then wonders why the next guy has to drill out snapped bolts. Aim low, sleep easy.
