In the modern industrial architecture, the Galvanised Self Tapping Screw stands as a fundamental yet critical component. Unlike traditional fasteners that require pre-drilled and tapped holes, self-tapping screws create their own mating threads in the material—usually metal or plastic—significantly reducing assembly time and labor costs. The global market for these fasteners has seen a paradigm shift towards high-corrosion resistance, driven by the expansion of renewable energy infrastructures and the electric vehicle (EV) revolution.
Advanced carbon steel and stainless steel alloys are treated with electro-galvanization or hot-dip galvanizing to provide a sacrificial zinc layer, preventing oxidation in harsh environments.
Self-tapping screws must maintain high shear strength and surface hardness. Our manufacturing process ensures a perfect balance between core ductility and surface hardness.
With the rise of "smart factories" and automated assembly lines, the demand for dimensionally consistent, high-tolerance galvanised screws has surged by 15% annually.
Located in the industrial hub of Wenzhou, Zhejiang Jifeilong Instrument Technology Co., LTD. represents the pinnacle of Chinese fastener engineering. Since 1999, we have transitioned from manual processing to fully automated, AI-integrated production lines.
Information Gain: While many suppliers focus only on price, we focus on the "Total Cost of Ownership" (TCO). By utilizing fully automated production, we reduce the defect rate to less than 50 PPM (Parts Per Million), ensuring that high-speed automated assembly lines in Europe and North America never stall due to fastener irregularities.
Full-chain automated grinding, threading, and quality inspection.
ISO9001 certified protocols applied to every raw material batch.
Standardized components shipped within 3-5 days globally.
Expert OEM/ODM services for niche industrial applications.
Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) is located at the Oujiang Port in Wenzhou City. We mainly engage in the integrated manufacturing and sales of various electrical switches, shafts, plastic products, and hardware components. Our products are widely used in home appliances, solenoid valves, electronics, automobiles, filtration equipment and other fields.
The company adheres to the tenet of "seeking truth from facts and quality first", strictly implements the latest national and international quality standards, and strives to become a high-quality global supplier of components.
Our screws and rivets are core to Molded Case Circuit Breakers (MCCB) and Miniature Circuit Breakers (MCB), providing the structural rigidity needed for high-voltage safety.
Corrosion-resistant galvanised fasteners are utilized in EV charging pile connectors and battery housings, where environmental exposure is a constant factor.
Custom valve core iron cores and nozzle components for water valves and solenoid valves require high-precision fastening to ensure leak-proof performance.
From HVAC units to kitchen electronics, our high-durability hardware components ensure a longer lifespan for consumer electronics.
Used extensively in mounting solar panels and steel frame construction where "drill-free" fastening is a significant time-saver.
Need a specific thread pitch or a custom zinc coating thickness? Our engineering team specializes in solving complex assembly challenges.
The industry is moving towards "Smart Fastening"—where the fastener itself is designed for 100% recyclability and minimum environmental impact. We are investing in trivalent chromium (Cr3+) galvanization, which offers superior corrosion protection without the toxic impact of older methods. Additionally, "Lightweighting" in the automotive sector has led to the development of high-strength, thin-diameter screws that provide the same clamping force as larger traditional bolts.
A: Self-tapping screws tap their own thread but usually require a pilot hole in harder materials. Self-drilling screws (often called Tek screws) have a drill-point tip that eliminates the need for any pre-drilling.
A: Galvanised screws are generally more cost-effective and provide excellent corrosion resistance for outdoor or industrial use. Stainless steel is used for extreme corrosion or aesthetic needs, but galvanised carbon steel often offers higher tensile strength.
A: Yes. While we have massive automated capacity for millions of units, we also support engineering samples and initial production runs for OEM/ODM clients.
A: We implement strict QC protocols at every stage—from raw material procurement to final shipping. We are ISO 9001 certified and use automated optical sorting for high-precision orders.
Established in 1999, we are a professional manufacturer of high-precision hardware components for the global electrical and automobile industries.
Strategic Goal: To provide the precision foundations for global industry with excellence and innovation.
