There are many ways to classify rivet nuts, so they can also be divided into many types. According to the material, it can be divided into carbon steel, stainless steel, and aluminum. According to the appearance and shape, there are cylindrical, half-hexagon, full hexagon, etc.; according to the flange shape, it can be divided into flathead and small head There are several types such as countersunk head, etc.; whether the through-hole is through can be divided into two types: through-hole and blind hole; according to the size, there are several types such as MMMMMMM12. Therefore, it may be better and more convenient for those who do not understand to choose a custom rivet nut .

The distance between the overlapping parts of the two mating thread profiles in the direction perpendicular to the thread axis, etc. The nominal diameter of the thread is the nominal diameter of the pipe thread, except for the pipe inner diameter, and the outside diameter is the nominal diameter. The thread has been standardized, and there are two metric and imperial systems. One end of the nut is made into a non-circular closing or is slit and then radially closed. When the nut is tightened, the closing is expanded, and the elastic force of the closing is used to compress the screw threads. The anti-loose structure is simple and reliable and can be disassembled and assembled many times without reducing the anti-loose performance. Its working principle is generally self-locking by friction. The types of self-locking nuts classified according to their functions are those with embedded nylon rings, those with neck closures, and those with metal anti-loosening devices.

Of course, the performance effects of the knurled rivet nut are also good for flying shovels.
