6. Summary

The appearance characteristics of rivet nuts include shape, structure, size, surface characteristics, material and color. These features not only affect the aesthetics of the product, but also closely related to the performance and service life of the product. Therefore, when selecting and using rivet nuts, it is necessary to pay attention to their appearance quality to ensure that they meet the standards and requirements.
