304 Bimetal Clad Screws


Scope of Application

Suitable for mechanical fixing systems in highly corrosive environments, such as coastal plants, paper mills, tobacco processing facilities, and areas with constant 270% humidity. Can be used with battens, metal gaskets, or sleeves.


Technical Advantages

  • 304 stainless steel screw shank: Offers exceptional corrosion resistance, ensuring long-term durability of the screw body in harsh environments

  • High-hardness 435 composite drill tip: Solves the common issues of softness and poor self-tapping performance associated with 304 material, enabling rapid self-drilling and ensuring quick, efficient installation
