OVERVIEW
Overview of Bi-metal Self-drilling Screws
Core Advantage: Bimetallic Structure with Wide Applicability
Developed under a US-standard quality management system, our Bi-metal Self-drilling Screws offer a premium fastening solution for demanding environments. Featuring a sophisticated composite structure of 300 series stainless steel and high-strength alloy steel, these fasteners deliver an optimal balance of high toughness and exceptional penetration power, effortlessly drilling through steel or aluminum plates up to 12.7mm thick.
To ensure long-term durability, the screws are treated with advanced bright anti-corrosion coatings, enabling them to withstand over 2000 hours of salt spray testing without red rust while effectively eliminating the risk of embrittlement. Fully compliant with both ANSI and GB standards, our bi-metal screws undergo rigorous quality control to provide high strength, superior reliability, and excellent compatibility across diverse industrial and construction applications.
ADVANTAGES
Advantages of Bi-metal Self-drilling Screws
Bi-metal Composite Structure
By utilizing advanced seamless welding technology, these fasteners combine a 300-series stainless steel body for superior corrosion resistance with a high-strength alloy steel drill point for powerful penetration. This engineered structure optimizes the balance between performance and cost while effectively preventing brittle fractures and enhancing impact resistance.
Superior Corrosion Resistance
The stainless steel section provides inherent protection against the elements, while the alloy steel drill point is treated with a specialized high-performance coating. This dual-protection approach ensures that the overall anti-corrosion capability far exceeds that of standard carbon steel screws, maintaining structural integrity in harsh environments.
Exceptional Versatility & Material Compatibility
Specifically designed for joining dissimilar materials—such as aluminum alloy profiles to steel structures—these screws are the ideal solution for preventing galvanic corrosion. They offer a professional and reliable fastening method for diverse architectural and industrial applications, ensuring long-term stability across different metal interfaces.
