There are many classifications of rivet nuts, such as flathead, small head, hexagonal, half-hexagonal rivet nuts, there are also through holes, blind holes, knurled and non-knurled rivet nuts. No matter what type of rivet nut, it is indispensable in our lives.

The rivet nut can also solve the problem of "yellow water" after a long time in the air conditioner shell and can prevent problems such as false welding. Now the widely used hexagon socket nut is also a kind of rivet nut. It can be more convenient to use a long-handled wrench to tighten or loosen. The wrench is an outer hexagon, which coincides with the bolt. This kind of inner hexagon nut bolt can be used on occasions that require a compact machine and are generally out of reach of a wrench.

Rivet nuts are mainly used in non-structural bearing bolt connections, such as the connection of interior parts such as highway buses, railbuses, and boats. The improved rivet nuts that can prevent spin are more excellent than the pallet nuts for aircraft. The advantages of rivet nuts are lighter weight, no need to fix the pallet nuts with rivets in advance, and the back of the substrate can still be used without operating space.

Since the stainless steel rivet nut is deformed under the condition of axial pressure applied at its two ends, the force is better than the bulging shape in which the radial pressure is applied to the simple shape or the pipe material. The length of the stainless steel rivet nut will be shortened after riveting, and its shrinkage is related to its material plasticity and size. In order to prevent the bulging coefficient from exceeding the allowable value and causing cracks in the bulging, the amount of shrinkage must be controlled.
