In the modern construction and industrial landscape, the China Hex Head Roofing Screws sector has evolved from simple hardware production into a high-tech engineering discipline. As global infrastructure demands increase, the necessity for fasteners that offer both structural integrity and long-term weather resistance has never been greater. At Zhejiang Jifeilong Instrument Technology, we bridge the gap between traditional reliability and future-ready automation.
Our hex head roofing screws are engineered using advanced cold-heading technology, ensuring that every fastener meets rigorous international standards such as DIN, ANSI, and AS3566. By integrating EPDM (Ethylene Propylene Diene Monomer) sealing washers, we provide a leak-proof solution that withstands extreme UV exposure and thermal cycling.
Application of Ruspert, Dacromet, and mechanical galvanizing for C3/C4 environment durability.
Specially hardened drill points that penetrate heavy-gauge steel without pre-drilling.
Engineered hex heads designed to eliminate cam-out and ensure consistent seating torque.
Located in the heart of Wenzhou's industrial cluster, we leverage a comprehensive supply chain—from high-grade steel wire sourcing to advanced surface treatment facilities. This geographical advantage allows us to offer the most competitive pricing without sacrificing the quality of the raw material (C1022A, SS304/316).
Unlike traditional workshops, our factory utilizes fully automated production lines. Each batch of hex head screws undergoes optical sorting and mechanical stress testing. We implement strict ISO9001 protocols, ensuring that "Quality First" isn't just a slogan but a measurable metric.
Our engineering team provides deep "Information Gain" by analyzing your specific environmental conditions. Whether you need screws for high-salinity coastal zones or heavy industrial chemical plants, we customize the coating thickness and washer composition to match.
The global push for green energy has increased demand for long-life fasteners used in PV solar mounting systems on metal roofs. Our screws are now engineered to last 25 years, matching the lifecycle of solar panels.
There is a significant shift away from hexavalent chromium coatings. We are leading the transition to eco-friendly, chrome-free surface treatments that comply with REACH and RoHS standards.
Global enterprises are moving toward "Value-Engineered" sourcing. They no longer look for the cheapest screw but the one that reduces total cost of ownership by preventing roof leaks and structural failure.
High-volume fastener supply for large-scale logistics hubs, ensuring fast installation and seismic resistance for metal cladding and roofing.
As seen in our original content, we provide high-precision copper parts and rivets for EV charging piles, demonstrating our versatility in the hardware and electrical sector.
Precision hex head screws for light-gauge steel (LGS) construction, providing superior pull-out strength and aesthetic finishes.
Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) was established in September 1999. Located at the Oujiang Port in Wenzhou City, we have built a legacy of precision manufacturing over two decades. We mainly engage in the integrated manufacturing and sales of various electrical switches, shafts, plastic products, and hardware components.
By implementing strict quality control in every production link, from raw material procurement to finished product delivery, the company has passed the ISO9001 certification. Through technological and equipment transformation, it has now achieved fully automated production capacity. We strive to become a high-quality global supplier of components, upholding the spirit of "Quality First, Reputation Supreme."
Type 17 points are designed with a sharp flute for timber applications, while self-drilling points (often called Tek screws) have a drill-bit tip designed to penetrate metal sheets without pre-drilling.
EPDM is a synthetic rubber that provides a thermal barrier and a watertight seal. It maintains elasticity even under extreme temperature fluctuations, preventing leaks that cause structural rot.
We use high-precision grinding and multi-stage stamping. Each electrical component is tested for conductivity and mechanical shear strength to ensure safety in circuit breaker applications.
We offer full design-to-delivery services. Our engineers can develop custom head styles, thread pitches, and coating combinations based on your project's technical blueprints.
