Material

Alright, so most stainless steel self clinching round rivet bush units use austenitic stainless steel. AISI 304 (aka A2) is the common choice because it handles corrosion pretty decently in everyday situations. But if you're dealing with chlorides,like saltwater or bleach or acids, you'll want AISI 316 (A4). That's the pick for marine stuff or places with harsh chemicals.

Both 304 and 316 grades meet common stainless steel specs like ASTM A666. They've also got decent strength and hardness, which means these self clinching round rivet bush fasteners work reliably for heavier-duty jobs where you need a permanent, no-fail grip.

How it works

This stainless steel self clinching round rivet bush is made for permanent, vibration-proof fastening. Here’s how it works: you stick the expanded part at the bottom into a pre-drilled hole. When you install it,usually with a rivet gun or a press,this part deforms on the backside (the side you can’t see) and bulges out, creating a solid mechanical lock. At the same time, the flange and knurling on the nut grip the surface and spread the pressure when you tighten it down.
