I'm a machinist and know well how much leverage you get with a fine thread pitch. I see over-tightened hardware almost daily where I work, and often tell employees to be more gentle when applying torque to threaded things. There is one particular piece of hardware on a few of our machines, it's a sensor that is held in place with small allen head screws, and every time I have to reset the machine for a different job and move those sensors, I also have to go to my locker and get my bottle with more of those same small screws in order to replace the ones that have been stripped out by whomever was last to move them. Drives me nuts. Do your small threaded and finely machined hardware a favor and be more gentle with it!
