In the rapidly evolving landscape of global construction and industrial manufacturing, the demand for high-efficiency fastening solutions has never been greater. As a premier China Self Drilling Tek Screws Supplier & Manufacturer, Zhejiang Jifeilong Instrument Technology Co., Ltd. understands that the "drill point" is more than just a tip—it is the catalyst for structural integrity. Self-drilling screws, often referred to by the brand name "Tek" screws, have revolutionized the way metal-to-metal and wood-to-metal connections are executed.
By integrating the drilling, tapping, and fastening processes into a single movement, these components eliminate the need for pilot holes, significantly reducing labor costs and assembly time. However, achieving the "Information Gain" in this sector requires looking beyond the basic functionality. It involves a deep understanding of metallurgical properties, drill point geometry, and the corrosive environments of the 21st century.
Located in Wenzhou, the "Hardware Capital," we leverage a massive ecosystem of raw material providers and specialized heat-treatment facilities. This proximity allows for rapid prototyping and unmatched cost-efficiency.
Formerly Yueqing Feilong Instrument Factory, our transition to Zhejiang Jifeilong Instrument Technology Co., Ltd. represents our shift toward AI-driven precision. We utilize advanced grinding and fully automated cold-heading machines to ensure ±0.01mm tolerance.
Our facility is designed for high-volume output without compromising E-E-A-T standards. With 24/7 technical support and express shipping, we bridge the gap between Chinese production and global demand.
A high-quality Self Drilling Tek Screw is defined by its ability to pierce thick steel without burning the tip or shearing the head. At Jifeilong, we focus on three critical dimensions:
✅ Vickers Hardness: Core 320-450 HV, Surface 550-750 HV.
✅ Torque Resistance: Exceeds DIN 7504 standards by 15%.
✅ Drill Speed: Average penetration time < 2.5 seconds in 2mm steel.
✅ Concentricity: Absolute center alignment for wobble-free driving.
In the era of modular construction, Tek screws provide the rapid fastening needed for steel frames and roof cladding, ensuring seismic stability and weatherproofing.
Stainless steel bi-metal screws are essential for outdoor photovoltaic arrays, preventing galvanic corrosion between aluminum rails and steel supports.
Leveraging our experience in EV charging pile components, we provide high-vibration resistant fasteners for battery housing and charging station enclosures.
Integrating with our valve core accessories and circuit breaker rivets, our fasteners support the internal structural assembly of high-precision electrical switches and solenoid valves.
For international procurement managers, sourcing from China is no longer just about the lowest price—it's about Supply Chain Resilience and Technical Compliance. We address the primary pain points of global enterprises:
We strictly implement national and international standards. Our ISO9001 certification and 3C compliance ensure that every batch of hardware—from pins and shafts to Tek screws—is traceable.
Standard fasteners don't always fit specialized needs. Our engineering team provides free samples and tailored designs for unique thread pitches or head styles (Hex, Wafer, Pan, Flat).
From raw material spectroscopy to automated optical sorting (AOI) for final packaging, we ensure zero-defect delivery for high-stakes electrical and automotive applications.
Established in September 1999 (formerly Yueqing Feilong Instrument Factory), we are located at the Oujiang Port in Wenzhou City. Our facility houses complete production, processing, and grinding departments. We specialize in the integrated manufacturing of electrical switches, shafts, plastic products, and hardware components.
By implementing strict quality control in every production link, we have won the trust of over 100 enterprise customers in China and are expanding rapidly into the international market. Our enterprise spirit—"Quality first, reputation supreme, people-oriented"—guides our path toward becoming a high-quality global supplier of components.
