1. The protection of the product should be strengthened during the storage of stainless steel screws. In a dry environment, the electroplated iron screws should not be placed in a humid place. In addition, be careful during the packaging process and not violently subpackage. Non-standard parts with special requirements need to be wrapped in mesh bags or other objects, and pay attention to avoid collisions with each other.



3.5 Mm Nuts And Bolts



2. The hardness of a stainless steel screw indicates the ability of a material to resist hard objects pressed into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance. Commonly used hardness indicators are Brinell hardness, Rockwell hardness and Vickers hardness.

3. When testing the hardness of stainless steel nuts, the bolts without heat treatment only need to make the surface hardness within the qualified range. If it is a heat-treated bolt, it is necessary to have a large hardness on the surface without a diameter. The hardness test is at 1/2R of the surface, and the hardness meets the standard.
