Absolutely; I've also worked with screws that were, as far I as I could understand, purposely made of less rugged metal to ensure that when they were tightened against the object they were meant to fasten (made of plastic), they would strip before damaging it. Still sucks to accidentally strip a screw that really should be that tight!
