    Key Features

    Our self-tapping screws are crafted from food-grade 304 stainless steel and treated to achieve metric Grade 12.9 ultra-high strength, overcoming the traditional hardness limitations of standard stainless steel. Featuring a countersunk Phillips head design, these screws can be installed flush with the workpiece surface for a zero-profile finish, making them ideal for precision electronics and architectural decoration. We have optimized the thread geometry for different substrates (metal, wood) to ensure low-torque driving with high-torque clamping, effectively preventing stripping. As a superior alternative to standard Tek screws, these fasteners perform exceptionally well in thin sheet metal connections, providing an intelligent fastening solution that balances aesthetics with high load-bearing capacity.

    Precision Manufacturing Process

    From wire rod to finished product, we strictly adhere to multiple international standards including ISO, DIN, ANSI, and GB. Utilizing multi-station cold forging technology, we ensure shank diameter tolerances are controlled within microns. Threads are formed through a precision thread rolling process to enhance fastening force. For non-standard requirements, we employ optical imaging sorters to reject minute defects like head cracks. In post-treatment, we offer a wide range of surface finishing options: from conventional zinc plating and nickel plating to highly corrosion-resistant Hot-Dip Galvanizing (H.D.G.), as well as decorative polishing and black anodizing. We even provide food-grade passivation treatment, ensuring every screw has a prolonged fatigue life in demanding environments.

    Transparency & Customization

    As a source factory, we are committed to breaking down the information barriers of traditional trade. From mill certificates for raw materials to hardness grades (covering Grade 4.8 to Grade 12.9, as well as A2-70 and A4-80 marine-grade stainless steel), all test data is traceable. We support full-chain customization: dimensionally, we can adjust thread length and head thickness according to drawings; functionally, we can combine processes like sandblasting, electrophoretic coating (e-coating) , or chrome plating. Whether you need British Standard (BS) fasteners or require a special colored anodized finish, we offer small-batch sampling. This ensures that when you purchase fasteners from us, you not only receive high-quality products but also full transparency and control over the entire process, from material selection to packaging.

    Flush Embedded Design

    Flush Embedded Design Balancing Safety and Aesthetics

    The core advantage of the Phillips Countersunk Head Machine Screw lies in its 90° countersunk cone angle. Once installed, the screw head embeds completely into the workpiece surface, delivering an unobtrusive, perfectly flush connection. This not only streamlines the appearance of electronic enclosures, furniture panels, and machine guards but also fundamentally eliminates snagging hazards caused by protruding screw heads—enhancing overall safety in mechanical assembly and architectural hardware. Driven by a universal cross recess, it enables fast one-handed fastening, dramatically boosting assembly efficiency while maintaining a compact structure.

    Corrosion Resistance

    Superior Corrosion Resistance Engineered for Harsh Environments

    We supply A2-70 (304 stainless steel) and A4-80 (316 stainless steel) grades, precisely manufactured to ISO 7046, DIN 965, and GB/T 819 standards. The 316 stainless steel countersunk screws excel in chloride-ion resistance, reliably passing 720+ hours of salt spray testing to endure humid conditions and outdoor installations far better than ordinary black-finished carbon steel. The 304 option is perfectly suited for standard indoor and mild outdoor use. For budget-sensitive applications, we also offer 4.8 and 8.8 grade carbon steel with electro-galvanizing or hot-dip galvanizing.

    Global Standard Coverage

    Strong Full-Thread Locking with Complete Global Standard Coverage

    Spanning a broad diameter range from M2 to M12 and lengths from 5mm to 120mm, the full-thread design ensures these Phillips Flat Head Machine Screws deliver continuous, stable clamping force to effectively resist vibration loosening. Strictly compliant with GB/T 819.1, ANSI B18.6.3, and other international standards, the extensive dimensional range seamlessly fits assembly lines for electronics, furniture, machinery, and outdoor engineering.
