    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.

    Our open type blind rivets are available in 304/316 stainless steel, anti-rust aluminum and galvanized carbon steel. The mandrel adopts stainless steel or carbon steel for optional matching to satisfy different strength and corrosion resistance requirements. 316 stainless steel performs well in chloride corrosion resistance, ideal for coastal and humid environments. Aluminum rivets feature light weight and non-magnetism, while carbon steel with galvanized finish enhances rust protection. They are widely used in automotive sheet metal, electronic equipment and furniture manufacturing for long-term stable riveting.

    Large Flange Structure
    Large Flange Blind Rivet Structure

    Designed with large flange round head, it expands the bearing contact area effectively and avoids piercing thin plates, plastic parts and soft materials, perfectly suited for furniture panels and electronic chassis. The blind rivet structure only requires single-side operation without tapping or welding, fitting enclosed or single-side accessible assembly scenes. The rivet shell expands evenly to form firm clamping force, preventing loosening and falling off during long-term service.
