Could you be more generic?
Ha ha...sorry.
I'd say don't use them if the snow around the crevasse is unconsolodated and requires a picket or dead man.
Otherwise, more specific questions??

Also don't try to sink a screw if you're on a moraine. :-)
But seriously, in a crevasse rescue situation, if you can make a screw part of your anchor, then do it.
That's assuming, as Brian pointed out, that the conditions allow you to place a screw at all. You may need to dig/hack a little ways below the surface to get to ice solid enough for a good placement. If you can't get to solid ice, use a snow anchor instead.
What sort of scenario did you have in mind?
