Bully Clutch Screw Size

Button head 4-40 X 3/16"
Looks like the others covered it before I saw your post.
They may be difficult to find locally -- try better (old) hardware stores or you'll end up ordering them through MSC, Enco, Grainger, etc. We've got them in stock if you need as well, or most kart shops should have them.
