Products Process
These Hex Head with Washer Zinc Self-Drilling Automotive Screws are manufactured using advanced cold forging techniques, ensuring precision and high-quality standards. The raw material, typically high-carbon steel or stainless steel, is carefully selected for its strength and toughness. The screws undergo heat treatment to improve their hardness and tensile strength. After the basic shaping process, the screws are coated with a zinc layer for added corrosion resistance, providing excellent protection against rust and wear, even in harsh automotive environments. The self-drilling tip is formed with precision, allowing the screw to easily penetrate without the need for pre-drilled holes. The hex head is crafted to provide a secure grip for installation using a standard wrench or socket tool.
