To make the uniform thread micro self clinching nut work better and last longer, they often come with different surface coatings. Aluminum ones usually get a clear or yellow chromate coating to fight rust. Steel types,including these riveted nuts are often zinc-plated (clear, yellow, or black) or cadmium-plated (where it’s allowed). Stainless steel versions rely on their natural rust resistance, but sometimes they get special surface treatments too. These coatings keep them from corroding and make installation go smoothly.
The uniform thread micro self clinching nut is way smaller than regular rivet nuts. Common thread sizes are from M2 to M5, with tiny mandrel and body diameters to match. Important specs include the grip range (how thick the materials can be that it clamps), head styles (usually countersunk or low-profile dome), and the total height when installed.
For each type of UN miniature riveted nut, having exact size details is key. That way, you can pick the right part for your hole size and material thickness.
To install the uniform thread micro self clinching nut, you’ll need a standard rivet nut tool. Make sure the tool’s mandrel and nosepiece are the right size for the specific nut. Apply enough force so the rivet shank fully forms against the material, creating a solid bearing surface on the blind side. Installing it properly ensures the locking collar works as it should and gives the nut the best vibration resistance and pull-out strength.
When installing uniform thread micro self clinching nuts, a standard rivet nut tool must be used. Ensure the tool's mandrel and tip dimensions match the specific nut. Apply sufficient force to ensure the rivet shank fully seats against the base material, forming a solid bearing surface on the blind hole side. Correct installation ensures the locking ring functions properly, providing vibration resistance and preventing easy removal.
