    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.

    Rust-proof material

    Rust-proof & Corrosion-resistant Stainless Steel Material

    Made of AISI 304 stainless steel (A2-70). High chromium content forms a dense passivation film, preventing rust in humid, salt-spray, outdoor, or chemical environments. No plating needed – retains natural metallic luster. Ideal for marine equipment, outdoor furniture, and bathroom assembly. Even after long-term exposure to rain or high humidity, it stays bright, eliminating disassembly difficulties and connection failure caused by corrosion.

    Tightening & Anti-Loosening

    Metal Material for Tightening & Anti-Loosening

    304 stainless steel offers tensile strength ≥700MPa. The self-tapping sharp thread bites tightly into sheet metal, plastic, or wood, creating an internal thread locking effect. The large pan head increases bearing area, preventing thin material deformation or indentation. Metal material never ages or becomes brittle, maintaining stable clamping force under vibration or temperature changes – ensuring lasting, reliable connections without extra lock washers.

    Wear Resistance

    Long Service Life with High Wear Resistance

    Stainless steel substrate with passivation offers high hardness and no plating peeling risk. The Phillips drive and large pan head reduce tool slippage; the self-tapping thread resists wear during repeated assembly/disassembly. Proven in durability tests, this product performs long-term in high-vibration or frequent-maintenance applications (e.g., appliance housings, vehicle interiors) – resisting thread stripping or wear, greatly reducing replacement frequency and maintenance costs.

    Frequently Asked Questions
    Q1: What are the primary benefits of using 304 stainless steel for these screws?

    A1: 304 stainless steel provides exceptional corrosion resistance and durability, making it perfect for humid or outdoor environments where standard carbon steel would rust.

    Q2: Do I need to pre-drill holes for these self-tapping screws?

    A2: While they are designed to tap their own threads, a small pilot hole is often recommended in harder materials to ensure precise alignment and prevent material splitting.

    Q3: Can these screws be customized for specific industrial requirements?

    A3: Yes, we offer flexible customization for head shapes, slot types, special materials, and personalized packaging to meet your specific project needs.

    Q4: Are these screws suitable for high-vibration applications?

    A4: Absolutely. The sharp self-tapping threads bite tightly into the substrate, creating a locking effect that maintains stable clamping force even under vibration.

    Q5: How do you ensure the quality of each batch of screws?

    A5: We utilize a comprehensive quality control system including raw material source locking, full batch traceability, and fully automatic optical sorting for 100% precision.

    Q6: What technical support do you provide for product selection?

    A6: We offer on-site failure analysis, selection calculations, BOM optimization, and guidance on installation tool selection to ensure the best performance.
