How is the material type for nuts determined?

The material type for nuts is determined by markings on the nuts. These markings are standardized indicators that provide information about the material composition and strength of the nut, ensuring that the correct type is used for specific applications. Proper identification via these markings helps maintain safety and structural integrity in mechanical applications.

In contrast, while weight, luster, and diameter can provide some information about a nut, they do not reliably indicate the material type. Weight can vary widely between different materials and sizes, luster may be affected by oxidation or coatings, and diameter alone does not inform about the metal composition. Thus, relying on markings is the critical method for determining the material type of nuts.
