In the contemporary industrial landscape, the demand for China Self Drilling Tapping Screws has transitioned from simple hardware procurement to a strategic component of assembly efficiency and structural integrity. As global industries pivot toward Industry 4.0, the role of precision fasteners has never been more critical. These components are the unsung heroes in the construction of modular data centers, renewable energy solar arrays, and high-performance automotive platforms.
The "Information Gain" in today’s fastening market lies not just in the supply of products, but in the integration of material science and geometric optimization. Zhejiang Jifeilong Instrument Technology Co., LTD. recognizes that a self-drilling screw must perform three distinct operations—drilling, tapping, and fastening—in a single, high-speed motion. This requires a profound understanding of metallurgical hardness gradients and point geometry that only a specialized manufacturer with decades of experience can provide.
Optimized fasteners for EV charging piles and battery housing, ensuring vibration resistance and electrical conductivity compliance.
Heavy-duty self-drilling solutions for metal roofing and steel frame construction, featuring advanced anti-corrosion coatings like Ruspert and Dacromet.
Ultra-tight tolerances designed for robotic pick-and-place systems, reducing downtime in high-volume electronics manufacturing.
Utilizing C1022A premium carbon steel with precise heat treatment to achieve a surface hardness of HV 560-600 while maintaining core ductility to prevent snapping under torque.
Development of the #5 drill point capable of penetrating up to 12.5mm of heavy-gauge structural steel without the need for pilot holes, drastically reducing labor costs.
Implementing eco-friendly trivalent chrome plating and ceramic coatings that provide 1500+ hours of salt spray resistance for offshore and coastal applications.
Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) was established in September 1999. Located at the strategic Oujiang Port in Wenzhou City, we have developed a comprehensive ecosystem for production, processing, and grinding. Our expertise spans the integrated manufacturing of electrical switches, shafts, plastic products, and high-precision hardware components.
Our products serve as the backbone for home appliances, solenoid valves, electronics, automobiles, and filtration equipment. By implementing strict quality control at every stage—from raw material procurement to finished product delivery—we have secured our ISO9001 certification. Our commitment to technological innovation has led to a fully automated production capacity, ensuring consistency and reliability for over 100 enterprise customers across China and the global market.
Full compliance with DIN 7504 standards. Our self-drilling tapping screws undergo rigorous hydrogen embrittlement relief to meet CE directives.
Adherence to IFI-113 and ASME B18.6.4 standards. We provide SAE J78 compliant drill points for the American automotive and construction sectors.
Leveraging our Wenzhou manufacturing base to provide rapid logistics for the Japanese and Southeast Asian high-tech corridors.
We understand that supply chain resilience is a priority.浙江吉飞龙 (Zhejiang Jifeilong) offers Express Shipping (3-5 days for standard orders) and 24/7 Technical Support. Whether you are in the UAE, Germany, or the USA, our engineering team provides virtual consultations to solve on-site fastening challenges.
Self-drilling screws feature a point that acts like a drill bit, creating their own hole in metal. Self-tapping screws require a pre-drilled hole but create their own threads as they are driven into the material. China self-drilling tapping screws combine both functions for maximum efficiency.
Yes, we offer Bi-Metal self-drilling screws with a carbon steel drill point welded to a 304/316 stainless steel body. This allows for drilling into hard steel while providing superior corrosion resistance.
Our facility uses automated optical sorting machines (CCD) that check every screw for dimensional accuracy, head shape, and point sharpness, ensuring a defect rate of less than 50 PPM (Parts Per Million).
Torque settings vary by material thickness and diameter. Our engineering team provides custom torque-to-fail charts with every OEM/ODM order to ensure optimal clamping force without material deformation.
Zhejiang Jifeilong Instrument Technology Co., Ltd. is ready to provide the precision foundations for your next industrial breakthrough.
