I can ' t fint rivet in That size the hoes arena to big for 6 mm rivets .. Forego the rivet and just use 5200. All you really need to do is seal the mast.DO NOT put a stainless steel bolt or rivet in the hole just to fill it. Stainless will cause galvanic reaction and you don't need the strength of stainless for anything in that repair.
