The Stovebolt Site Forums The Shop Area Paint and Body Shop Fulton visor mounting screws

After a lot of refurbishing, measuring and procrastination I’m going to attempt to mount my Fulton 800 visor today but don’t know what size sheet metal screws to use. I’ve narrowed it down to stainless steel #8 X 3/4” Pan heads or #8 X 3/4” Flat heads. The instructions just say to “attach with the screws included”. Which head should I use? Should I use a finer thread? Also, would a shorter 5/8” length be a better choice?

Thanks
