Products Description
Bi-Metal Hex Washer Head Self-Drilling Screws are high-performance fasteners designed for efficient and secure fastening in a variety of applications, particularly in metal-to-metal and metal-to-wood connections. These screws feature a unique bi-metal construction that combines the strength of steel with the corrosion resistance of stainless steel, making them ideal for use in harsh environments. The hex washer head design provides a larger bearing surface, ensuring a tight seal and reducing the risk of stripping during installation. The self-drilling tip eliminates the need for pre-drilling, allowing for quick and easy installation, even in tough materials.

Products Process
The production of Bi-Metal Hex Washer Head Self-Drilling Screws involves several key steps to ensure high quality and performance:
Material Selection: The screws are made from a combination of high-strength steel for the body and stainless steel for the tip, providing both strength and corrosion resistance.
Forming and Shaping: The screws are formed using advanced cold forging techniques, which enhance the mechanical properties of the materials, ensuring durability and reliability.
Heat Treatment: The screws undergo heat treatment processes to improve hardness and tensile strength, ensuring they can withstand high loads and stresses during installation.
Drilling and Threading: The self-drilling tip is precisely machined to ensure efficient penetration into various materials, while the threads are rolled to enhance grip and holding power.
Surface Finishing: To further enhance corrosion resistance and aesthetic appeal, the screws may be coated with finishes such as zinc plating or other protective coatings.
Quality Control: Each batch of screws undergoes rigorous quality inspections, including dimensional checks, tensile strength tests, and corrosion resistance evaluations, ensuring compliance with industry standards.
