    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.

    High Tensile Carbon Steel
    01

    High Tensile & Hardness Carbon Steel Material

    Made of Q235 carbon steel with hardened treatment and black oxide finish. Compared to ordinary low-carbon steel screws, this product offers higher tensile strength (Grade 4.8 ≥400MPa, Grade 8.8 ≥800MPa) and increased hardness to prevent thread stripping or head breakage. When driving into hardwood or composite panels, its high strength ensures smooth penetration without deformation – strong and durable for heavy-load connections in furniture and construction.

    Metal Material Tightening
    02

    Metal Material for Tightening & Anti-Loosening

    The carbon steel substrate is heat-treated for excellent elastic limit and torsional strength. The self-tapping sharp thread bites deeply into wood fibers during driving, creating a "female thread" locking effect. Metal material never ages or becomes brittle, maintaining secure fastening under long-term vibration or temperature changes (e.g., outdoor wood structures, movable furniture). High preload is retained after tightening for reliable, long-lasting connections.

    Long Service Life
    03

    Long Service Life with High Wear Resistance

    Black oxide finishing increases surface hardness and provides self-lubricating properties, reducing friction wear between the screw and wood during assembly. The countersunk Phillips head fully embeds into the wood surface, preventing tool slippage or head damage. Proven in durability tests, the threads withstand repeated driving and removal without significant wear. Compared to common zinc-plated wood screws, this product offers superior wear resistance and lower replacement frequency in outdoor or repetitive-use applications.

    Frequently Asked Questions

    What is the advantage of the black oxide finish on these screws?
    The black oxide finish provides increased surface hardness and self-lubricating properties, which reduces friction during installation and enhances wear resistance compared to standard zinc plating.
    Are these screws suitable for use in hardwood?
    Yes. Due to the heat-treated Q235 carbon steel construction, these screws offer high tensile strength and hardness, allowing them to penetrate hardwood and composite panels without deformation or head breakage.
    Do you offer customization for specific project requirements?
    Absolutely. We provide flexible customization for head and slot shapes, special materials, extra-long specifications, and personalized packaging or labeling to meet your unique application needs.
    How do you ensure the quality and traceability of your products?
    We implement a strict quality control system including raw material source locking, furnace number batch traceability, and real-time salt spray monitoring. All process parameters are open and transparent.
    What technical support services do you provide?
    We offer comprehensive technical services such as on-site failure analysis, BOM optimization, installation tool selection guidance, and free sample making for testing.
    Can these screws withstand vibration without loosening?
    Yes, the self-tapping sharp threads bite deeply into wood fibers, creating a secure "female thread" locking effect that maintains high preload and prevents loosening under long-term vibration.
