SS Cap Rivet vs Aluminium Rivet vs Blind Rivet — Which is Best for Pressure Cookers?
SS Cap Rivet vs Aluminium Rivet vs Blind Rivet — Which is Best for Pressure Cookers?
If you manufacture pressure cookers, hardener cookers, steel cookers, fry pans, or kadahis, choosing the right rivet is one of the most important decisions you make. The wrong rivet means handles that rust, look cheap, or fail under pressure. The right rivet means a product your customers trust.
At Kamlesh Enterprises, Mumbai — manufacturer of SS cap rivets since 2004 — we answer this question every day. Here is our definitive comparison.
The 3 Main Rivet Types Used in Indian Cookware
1. SS Cap Rivet (SS Cap Aluminium Rivet) — The Industry Standard
An SS cap rivet has an aluminium body with a stainless steel (SS 202 or SS 304) cap on the visible outer face. This combination gives you the best of both worlds — the lightweight strength of aluminium for easy installation, and the premium mirror finish of stainless steel on the cookware surface.
Best for: Pressure cookers, hardener cookers, steel cookers, fry pans, sauce pans, dosa tawa, tawa, kadahi — all premium Indian cookware.
Why it wins: Mirror finish matches SS cookware. Fully corrosion resistant. Food safe (SS 202/304). Heat resistant. Cost effective. This is why 90%+ of India’s premium cookware manufacturers use SS cap rivets.
Sizes: 5×10 to 6×18mm. MOQ: 5000 pcs. Available from Kamlesh Enterprises.
2. Plain Aluminium Rivet — Budget Option
Made entirely from aluminium. Lightweight and easy to set, but the dull grey colour does not match stainless steel cookware. Used in budget and economy cookware ranges where appearance is not a priority. Also used in industrial applications.
Best for: Budget cookware, aluminium vessels, industrial assembly where aesthetics do not matter.
Why it loses for premium cookware: Dull appearance. Does not match SS surface. Can look cheap on retail shelves.
3. Blind Rivet (Pop Rivet) — For Closed-Back Applications
A blind rivet (also called pop rivet) is installed from one side only — ideal when you cannot access the back of the joint. It has a two-piece construction: a rivet body and a mandrel stem. The mandrel is pulled to expand the rivet body and then snaps off.
Best for: Applications where only one side is accessible. Used in RVs, trailers, aircraft panels, electronics enclosures.
For cookware: Less common in Indian cookware manufacturing. SS cap rivets are preferred as both sides of the cookware wall are accessible during handle assembly.

Frequently Asked Questions
What size SS cap rivet do I need for a pressure cooker?
For standard Indian pressure cookers (2L to 10L), the most common sizes are 5×12mm, 5×14mm, and 6×12mm. For larger or heavy-duty pressure cookers and hardener cookers, 6×14mm and 6×16mm are recommended. Contact Kamlesh Enterprises for size selection guidance specific to your cookware design.
What is the difference between SS 202 and SS 304 cap rivets?

Yes. SS 202 and SS 304 stainless steel are non-reactive and food safe even with acidic foods like tamarind, tomatoes, and citric ingredients commonly cooked in Indian pressure cookers.
