Carbon Steel Self Clinching Round Rivet Bush

Carbon steel self clinching round rivet bush is a fastener with a knurled pattern and has the following outstanding features:

The expanded rivet part lets you install it permanently on the backside with a strong hold, even if you can't see that side.

The knurled flange is built right in, so you don't need a separate washer. It stops the nut from spinning and spreads the pressure evenly when you tighten it.

The round nut body has deep threads, so it grips well when you screw in a bolt.

Being stainless steel means it won't rust and lasts a long time, even in rough conditions.

Surface treatment

Carbon steel self clinching round rivet bushes (actually stainless steel) are inherently rust-resistant, but to extend their lifespan, they undergo additional surface treatment before shipment.The most common passivation treatment involves soaking the stainless steel in acid. This removes any stray iron filings and strengthens the existing protective chromium layer. This helps it better resist corrosion, especially for 316 bushings used near salt or chemicals.

Sometimes we add other finishes. Electro-polishing makes the surface really smooth and clean. Or, we might throw on special lubricant coatings, like fluoropolymer. These coatings make the self clinching round rivet bush (stainless) easier to install by reducing the force needed to turn it, and they help stop the threads from sticking or tearing up when you tighten the bolt.

Customized sizes or special knurling patterns

We can customize these carbon steel self clinching round rivet bushes. That includes non-standard diameters, thread sizes, and even specific knurl patterns like diamond or straight to get better grip. Whether we can do your custom order and the minimum quantity you need depends on what exactly you want. Just send us the details of what you're looking for.
