In the modern industrial landscape, Self-Drilling and Self-Tapping screws represent the pinnacle of assembly efficiency. As a leading China factory, we recognize that these components are not mere hardware; they are the structural integrity of skyscrapers, solar arrays, and electric vehicles. The demand for higher torque resistance and anti-corrosive properties is driving a paradigm shift in fastener metallurgy.
Unlike standard screws, self-drilling variants incorporate a drill-bit point. This eliminates the need for pilot holes, drastically reducing labor costs and installation time. Our engineering team focuses on point geometry—optimizing the "flute" length to ensure efficient chip removal, which prevents overheating and maintains the integrity of the substrate.
Zhejiang Jifeilong Instrument Technology operates at the heart of the Wenzhou industrial cluster. Our resilience is built on vertically integrated manufacturing. From cold-heading to automated optical sorting, we control every variable. This ensures that even during global logistics volatility, our production lines remain agile and our lead times remain industry-leading.
The future of China's self-drilling screw factories lies in advanced surface chemistry. We are moving beyond simple zinc plating to high-performance coatings like Ruspert, Magni, and Geomet. These multi-layer systems offer over 2,000 hours of salt spray resistance, making them ideal for coastal construction and offshore energy projects.
Our factory is transitioning into a "Smart Factory" model. By utilizing AI-driven vision inspection systems, we can detect micro-cracks in thread forming that the human eye misses. This 100% inspection rate is why Jifeilong is trusted by Fortune 500 electronics and automotive firms.

Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) was established in September 1999. For over two decades, we have been a cornerstone of the Wenzhou industrial landscape. Located at the Oujiang Port, our facility spans the full spectrum of production: from raw material processing and grinding to high-precision assembly. We specialize in the integrated manufacturing of electrical switches, shafts, hardware components, and notably, specialized fasteners for the most demanding environments.
By implementing strict quality control in every production link, the company has passed the ISO9001 certification. Our mission is clear: "Be Realistic and Quality First." Through technological transformation, we have achieved fully automated production capacity, serving over 100 enterprise customers across China and expanding globally.
Our products are widely used in:
• Home Appliances
• Solenoid Valves & Electronics
• Automobiles (EV & ICE)
• Filtration Equipment & Power Systems
In high-UV and humid environments (like Southeast Asia), our Bi-metal self-drilling screws are essential. They drill through thick aluminum rails while providing the non-corrosive longevity of stainless steel.
Speed of assembly is critical. Our screws feature a "Speed-Point" design that bites into cold-formed steel (CFS) instantly, reducing fatigue for installers and ensuring air-tight construction.
As seen in our EV Charging Pile parts, electrical conductivity and vibration resistance are key. Our custom-threaded screws prevent loosening under the high-frequency vibrations of a moving vehicle.
A: It refers to the drilling capacity. A #3 point can typically drill through up to 0.175" of steel, while a #5 point is designed for heavy-duty applications, piercing up to 0.500" of hot-rolled steel without a pilot hole.
A: We utilize a strictly controlled post-plating baking process. For high-tensile fasteners (Grade 10.9 or higher), baking occurs within 1-4 hours of plating to drive out hydrogen atoms trapped in the steel lattice.
A: Yes. As a direct factory, we can manufacture Torx, Hex, Wafer, and Pan head designs tailored to your specific torque requirements and driver tools.
A: We are ISO9001 certified and our products can be manufactured to comply with DIN, ANSI, JIS, and GB standards. Third-party testing (SGS/TUV) for RoHS and REACH is available upon request.
