Small washers are for mounting racks to braze ons and bottle cages (if you are that kinda person), and some light mounting situations. Oversized washers are used to sandwich fork crown light mounts, SKS fender stays to drop out braze ons, and mounting front racks to fork crowns. We stock 18-8 grade stainless washers. They’re strong, highly corrosion resistant, but really, there is isn’t much more to a washer.
