    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.

    Product Highlights & Performance

    High Load Capacity

    Multi-Material & High Load Capacity

    Made of AISI 304/316 stainless steel or carbon steel, the 316 version resists salt spray corrosion, while carbon steel can be galvanized for enhanced rust protection. With sizes from 50mm to 200mm and a breaking strength up to 25kN, they deliver reliable load-bearing performance for marine, outdoor, and lifting applications.

    Quick-Open Design

    Quick-Open & Locking Design

    The one-touch spring gate allows easy opening with automatic rebound locking. Optional screw-locking or self-locking gates prevent accidental disengagement, meeting safety standards like EN 362. Tool-free single-hand operation balances convenience and anti-loosening security.

    Versatile Design

    Versatile Multi-Structure Design

    Multiple designs (basic, locking, eye-ended) fit ropes, chains, and anchor points. Polished stainless steel versions work in humid, salt spray environments without coating contamination, while carbon steel options offer excellent rust and wear resistance for outdoor, marine, and industrial lifting use.
