Japanese Industrial Standard
I was unaware of JIS. Owning Toyotas for years and never learned that the "Phillips" screws were actually JIS which was why my screwdrivers always had sloppy fit. Just learned this last night, now I could buy a set of Vessel brand screwdrivers which seem to be the only quality ones I could find however I will grind 1MM off a few old phillips screwdrivers for a better fit on my Japanese products
Not sure if I may run into JIS on offshore carbs etc for GT's
