    Screws for Hardibacker

    Hi I've only seen specific branded screws in 30+mm for Hardibacker boards, but they seem a bit long for some installations. However, some other basic screws don't always seem to finish flush on the surface. Am I missing a trick here? Should any screws really suffice? Cheers
