Stainless where rust simply isn't an option.
Coastal air, damp sheds, marine gear, anything that sits outside for years, that's where 304 stainless earns its keep over a standard steel or aluminium rivet. It won't streak or corrode, and it holds its strength through wet and dry cycles that would eat a cheaper fixing.
Sets the same way as any blind rivet, one hand riveter, one side of access, done in a squeeze. The dome head sits flush once it's pulled tight.
Full diameter and grip specs are in the tabs below. If you're picking rivets for a coastal or marine job, ask us which grade actually holds up out there.
