Equipment that needs to be maintained at high altitude or under complex working conditions requires screw loss prevention design. Although traditional captive screws can achieve the purpose of preventing falling off, because the diameter of the screw is smaller than the major diameter of the thread, it is difficult to match the gasket, and the gasket will be eccentric, which is easy to install. Scratch the surface of the product, affecting the corrosion resistance and appearance of the product.

Many customers ask what is the difference between a rivet nut and a rivet nut, and how to use it? Let's take a look at the difference between a rivet nut and a rivet nut with Yueluo.
