Industry Grade Countersunk Head Riveted Nuts

Alright, so these Industry Grade Countersunk Head Riveted Nuts are basically used to add a solid threaded point into materials that are either too thin to have their own threads or don't have threads at all. This lets you bolt other parts onto them securely. You see them a lot in sheet metal work—like when you need to attach panels on an electrical cabinet, put together the metal shell of a washing machine or fridge, or join the thin parts on some factory equipment. The "countersunk" head means the top of the nut sits flat, or flush, with the surface of the metal. That way, nothing sticks out to get in the way of other parts or make the final product look uneven.

They're also pretty common in making cars, used to fix things like interior trim panels, outer body sheets, and some parts underneath the vehicle. In construction equipment, you might find them holding lighter metal frames or some of the non-structural covers in place. They get used in other areas too, like putting together metal furniture frames or mounting brackets inside electronic gear. The nice thing is they can be installed into different materials—aluminum, steel, even some plastics—so they're pretty versatile for all sorts of assembly jobs. You don't need any fancy tools to put them in for most basic jobs, which keeps things simple and cuts down on maintenance time later.

These Industry Grade Countersunk Head Riveted Nuts are made from a few different materials that are pretty standard in factories and workshops. Which one to pick really depends on where you're using it and how much weight or force it needs to handle.

The most common and budget-friendly option is carbon steel. You'll see these nuts used a lot for general indoor jobs, like putting together electrical panels or the metal shells of appliances. Since plain carbon steel can rust, they usually give it a zinc coating. This plating gives it a basic layer of protection against everyday moisture and stops it from corroding too quickly in normal use.

The other go-to material is stainless steel. This is the better pick if the nuts are going to be outside, in a damp place, or anywhere near saltwater—think parts on the outside of a car, equipment on a construction site, or anything used near the coast. Stainless steel naturally fights off rust and moisture much better. The two grades you'll usually come across are 304 and 316. If the environment is especially tough or corrosive, like right by the sea, going for 316 is often the smarter move because it holds up even better.

Q: What are its standard specifications?

A: Okay, so when it comes to Industry Grade Countersunk Head Riveted Nuts, they're made to match up with common international standards, like DIN 7967 or ISO 15072. The sizes you can usually get run from M3 all the way up to M12, and they normally come with standard metric coarse threads. Their countersunk head is typically cut at a 90-degree angle, which is what lets the top sit flat and smooth with the material's surface. Which size you'll need just depends on how thick your workpiece is and the specs of the bolt you're using. We have a straightforward size chart available that shows all the options, so you can easily check and pick the right one for your job.
