    304 Stainless Steel Cross Recessed Countersunk Head Self-Tapping Screws01

    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.

    Multi-Material Series

    Multi-Material & Full Strength Series for Demanding Conditions

    Our clevis pins are made of AISI 304/316 stainless steel or 45#/40Cr alloy steel, with strength grades including A2-70 (304), A4-80 (316), and carbon steel grades 8.8/10.9. The 316 stainless steel version offers exceptional chloride corrosion resistance, passing ≥720 hours of salt spray testing to withstand harsh coastal and humid environments. Carbon steel options with electro galvanizing, hot-dip galvanizing, or black oxide finishes balance high strength and rust/wear protection.
    Standardized Precision

    Standardized Precision Design for High Fit Performance

    Manufactured to international standards including GB/T 882, ISO 2341, and DIN 1443, our pins feature a flat head with cross-hole and high-precision polished shaft. The smooth shaft minimizes wear during installation and operation, extending service life. When paired with cotter pins or R-clips, they provide dual anti-loosening security. The evenly distributed load on the flat head ensures stable performance under dynamic loads.
    Quick-Install Design

    Quick-Install Design for Efficient Assembly

    The cross-hole design allows fast locking with cotter pins: simply insert the pin through the clevis, secure it with a cotter pin spread open in the hole, and the connection is complete. No special tools are needed for disassembly, greatly improving assembly and maintenance efficiency. Customizable lengths suit applications from automotive trailers to marine equipment and industrial machinery.
