Screws are not recommended for fastening Hardiepanel or Hardielap siding. Nails are recommended by the manufacturer. There are pneumatic siding nails made just for this. I would go the extra mile and get the stainless steel ones. These nails have a thin flat head and will lie almost flush with the surface of the panel. You may not have to patch the holes before painting if using Hardipanel. They also work very well for blind nailing. A regular framing nail will bite into the board and will more easily rip through it.
