I end up going the other way a lot, using shorter screws. If you have an EMT connector in a handy box the device screws are going to be too long.
(I still like sleeving NM on a block wall vs the standoffs)
I know you can cut them but it is just as easy to simply use the right screw in the first place. I agree with E57, the screws included with equipment is more likely to be chosen based on price than quality. Some are very crude and not even a good fit in the threads.
