Stainless steel round self clinching nuts feature a raised, rounded head and are used as fasteners for sheet metal or thin plates. Xiaoguo® offers a variety of nut sizes and specifications, and custom sizes are also available.
The Expanded rivet round nut-Stainless steel is a kind of blind fastener. It's mainly used for permanent, high-strength threaded connections when you can only access one side of the workpiece. The key part is its split-sleeve body - when you install it, this sleeve expands outward.
You just use a regular threaded tool to set it. When you do that, the sleeve collapses and flares out behind the material. This creates a big, solid surface that holds things tight. The good thing is, it resists being pulled through really well and stays secure even with vibrations.
That makes it perfect for panels, extruded parts, and sheet metal assemblies. You know, the kind of places where you can't use normal nuts. And after installation, the round nut shape gives it a smooth finish, nothing sticking out or looking rough.

The main benefits of the Expanded rivet round nut-Stainless steel are its great blind-side fastening ability and strong strength for its size. The way it expands makes a big contact area, which spreads out the load well. That means it won’t pull out easily, even if you’re using thin or fragile materials.
When you install it, the parts lock together mechanically, so it’s really good at handling vibrations. Putting it in is quick, and you only need simple tools that are easy to find. Also, since it’s a standard size, it works with common bolts (like M3 to M12) and is easy to buy. That helps simplify assembly and makes inventory management easier for lots of different industrial uses.
Expanded rivet round nut-Stainless steel are often made from carbon steel types like 1018 or 1022. To fight rust, they usually get a zinc plating,either clear or yellow chromate,that meets ASTM B633 standards. This plating gives them a basic layer of protection.
If you need them for harsher conditions, there are stainless steel versions too, like SS304 or SS316. These don’t need extra plating because they already have bet
