    304 Stainless Steel Cross Recessed Countersunk Head Self-Tapping Screws01

    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-Material & Full-Size Coverage

    Our wire rope clips are available in two major material series: AISI 304/316 stainless steel and Q235 carbon steel. Stainless steel grades include A2-70 (304) and A4-80 (316); the 316 variant offers exceptional chloride corrosion resistance, passing ≥720 hours of salt spray testing to withstand highly corrosive marine environments. Carbon steel options in grades 4.8/8.8, with optional electro or hot-dip galvanizing, balance high strength and rust protection. Suitable for wire rope diameters from 2mm to 60mm.

    U-Bolt Design

    Standardized U-Bolt Design

    Featuring a classic U-bolt and serrated saddle plate structure, our clips comply with international standards including GB/T 5974, DIN 741, and EN 13411-5. The serrated saddle ensures uniform, high-traction clamping force to prevent wire rope slippage under load. Anti-loosening performance is enhanced by controlled pre-torque and tooth engagement, maintaining stability even in dynamic lifting and industrial applications.

    Installation

    Easy Installation & High Versatility

    Installation is quick and straightforward: simply form an eye in the wire rope, insert the U-bolt, fit the saddle plate, and evenly tighten the nuts per standard procedures, with no complex tools required. This significantly reduces on-site installation time and labor costs. With broad compatibility for various wire rope diameters, stainless steel clips perform reliably in wet environments without additional coatings.
