Yup, no need to order OEM replacement screws. Any metric screw of the correct size will be fine. Stainless screws have a certain attractiveness, but can sometimes be soft metal. I replaced most of mine with hex socket head screws so that I only need one tool to take most off, and I really don't care that much for phillips screws.
Life is a mortal adventure. Don't avoid all the risks.
