    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.

    Material & Weather Resistance

    Material & Weather Resistance

    Our wedge anchors are available in two major material series: AISI 304/316 stainless steel and carbon steel. The 316 stainless steel version features outstanding resistance to chloride ion corrosion, easily withstanding highly corrosive environments such as coastal salt spray and wastewater treatment plants. The carbon steel version offers SWRCH35K/45# options with hot-dip galvanizing, balancing high strength and outdoor rust prevention. With strength grades A2-70 and A4-80, and sizes ranging from M6 to M20, they deliver long-lasting and reliable anchoring.

    Wedge Locking Mechanism

    Wedge Locking Mechanism

    Featuring a core wedge-locking expansion sleeve design, tightening the nut drives the wedge block to expand under pressure, forming a 3D interlocking bite with the concrete hole wall to significantly enhance anchoring force. The tested anti-seismic and anti-loosening performance fully meets the C1/C2 high-fatigue load requirements of ETAG 001 Annex E. In dynamic load scenarios such as elevator shaft brackets and bridge guardrails, they can stably withstand repeated alternating loads.

    Fully Threaded Design

    Efficient Post-Installed Design

    The fully threaded integrated design allows the cutting depth to be adjusted arbitrarily according to on-site working conditions, eliminating the need for pre-embedded components and greatly reducing pre-construction preparation costs. The installation process only requires four simple steps: drilling the hole, cleaning the hole, inserting the anchor, and tightening the nut to the specified torque. This post-installed solution is especially suitable for scenarios such as existing building renovations and elevator guide rail installations.
