    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.

    Self-Drilling Sharp Tip

    Self-Drilling Sharp Tip – No Pre-Drilling, Save Time & Effort

    Built-in sharp self-drilling serrated tip penetrates drywall/plasterboard directly – no pre-drilling or hammering needed, completing drilling and installation in one step with an electric driver. Ideal for large-area or overhead work, reducing tool changes and steps. Countersunk cross (or flange) design ensures flush surface or larger load distribution, neat and surface-friendly – one person can finish batch fixing quickly.

    Foldable Metal Expansion Wings

    Foldable Metal Expansion Wings – Large Bearing Area in Hollow Walls

    Self-tightening foldable metal wings automatically expand into a butterfly shape after passing through the wall, closely hugging the back surface with a large bearing area that evenly distributes loads across drywall or partitions – effectively preventing local crushing or tearing. Made of high-strength spring steel with excellent elasticity, the wings self-lock after expansion – even long-term mounting of bathroom hardware, cabinets, or light electrical panels stays secure without loosening or pullout.

    Yellow Zinc Coating

    Bright Yellow Zinc Coating – Rust-Proof, Wear-Resistant & Long-Lasting

    Carbon steel substrate with high-gloss yellow zinc plating – dense and uniform coating effectively resists moisture, dust, and mild corrosion, suitable for kitchens, bathrooms, and interior partitions. Wing and thread surfaces resist wear and abrasion, maintaining elastic deployment and thread locking even after repeated use. Fatigue-tested, this anchor withstands static loads and light vibration without failure – extremely low replacement frequency, offering excellent cost-performance.
