Overview

Bi-metal screws are screws made of two different metals, which combine the characteristics of the two metals to provide excellent performance and durability. They are usually used in scenarios that require corrosion resistance, high strength or special conductivity.

Common bi-metal screw materials include SS304+SS410, SS316+SS410, SS304+SCM435, and SS316+SCM435. These combinations offer anti-corrosion performance that can reach 1000 hours.

• Self-tapping composite nails: Mainly used for the installation of photovoltaic support. Can punch 0.4-1.00mm iron plate.
• Self-drilling composite nails: Can penetrate 1-6mm iron plate.

Application of Bi-Metal Screws

1. Construction industry: In construction, it is widely used for the installation and fixation of steel structures, color steel plates, roof panels, etc. For example, when the color steel plate is fixed on the light steel keel, the self-drilling and self-tapping performance of bimetallic screws can quickly complete the installation, and its corrosion resistance can ensure the reliability of the connection in long-term use.
2. Manufacturing industry: Commonly used in the assembly of mechanical equipment, the connection of the body and engine in automobile manufacturing, etc. On the automobile production line, bimetallic screws can firmly connect parts of different materials together, such as connecting plastic panels to metal body frames. Its good comprehensive performance can adapt to complex working conditions and frequent vibrations.
3. Electronic and electrical industry: In electronic equipment, it can be used for the installation of circuit boards and the grounding connection of various electrical equipment. Due to its good conductivity and corrosion resistance, it can ensure reliable electrical connection between electronic components and prevent electrical failures caused by screw corrosion.
