Granted, I've worked on pretty much everything - which means I've run into more headaches than most. "I don't look for trouble, it finds me with alarming regularity..."

Some screws should not be re-used. Any carbon steel screw that is partially/wholly immersed in water, any steel screw subject to exhaust head, any fastener that locks through a deformed component (Nylon collar, deformed threads,) should not be reused if you have a choice.

I'm only a pessimist and a cynic because experience has shown that it's the best way for me to think...

Anytime!
