Render carrier board

Just bought some sheets to do an alcove ceiling and forgot to ask about screws.
Is it ok to use drywall screws. Thanks

Yeah if you want to lose ya fingers!

Outside? Use stainless.

Do not use drywall screws outside... over time they will rust (especially if covered in a render)

will end up with rust spots coming through, and maybe have the soffit boards fall if the corrode too much...
