I am really confused why or what paticurly are you riviting? if you are putting in a buckle why not just use chicago screws? they are crome plated, or come in brass. now if you are doing special belts and are looking for somthing different to put on the belts perhaps Ohio Travel bag would have something that you would like. if you use steel if they get wet they will turn the leather black. and aluminium flakes off so it looks like the leather has a lot of grey junk on it. still wondering what you are actually using the rivets for?
