    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.

    Multi-Grip Anti-Slip Ribs

    Multi-Grip Anti-Slip Ribs for Strong Anchoring

    The fish-scale/spiral anti-slip ribs on the sleeve embed into the hole wall from multiple directions, creating a 360° "multi-grip" holding force far superior to ordinary smooth sleeves. Combined with flexible longitudinal expansion slots, the sleeve expands evenly as the screw is driven in, tightly conforming to brick, concrete, or drywall holes – no spinning or loosening. The flange anti-sink rim prevents the sleeve from sinking into the wall, providing a solid base for hook hanging, reliably supporting everything from lightweight picture frames to heavy lamps.

    Metal Hooks Styles

    Metal Hooks in Multiple Styles – Corrosion-Resistant & Load-Bearing

    The included hooks come in two styles: closed ring (ideal for rope or chain hanging) and open J-hook (for quick attachment/removal). Made of carbon steel zinc-plated (blue-white/yellow zinc) or 201/304 stainless steel (A2-70), they resist rust and corrosion, suitable for kitchens, bathrooms, and damp environments. Load tests prove that properly installed hooks can withstand several times their rated load – no deformation or breakage over long-term use.

    Ready-to-Use Kit

    Ready-to-Use Kit – Quick Installation & Long Service Life

    Each set includes both the expansion sleeve and matching hook screw – no need to source separate components, ready out of the box. Industrial-grade nylon/PE sleeve resists impact and aging, lasting decades without becoming brittle; metal hooks feature multi-layer corrosion protection against moisture and mild chemicals. Designed for dual functions of anchoring and hanging, ideal for home decorations, bathroom hardware, electrical boxes, and lightweight panels – one installation, maintenance-free for years.
