In the evolving landscape of global industrial manufacturing, the demand for OEM Long Metal Screws has transcended basic assembly requirements. These specialized fasteners are no longer mere "hardware" but are critical structural elements designed to withstand extreme torque, high vibration, and corrosive environments. From heavy-duty infrastructure projects to the intricate internal housing of new energy vehicle (NEV) batteries, long metal screws provide the necessary clamping force over extended distances that standard fasteners cannot achieve.
As a leading Long Metal Screws Supplier and Manufacturer, Zhejiang Jifeilong Instrument Technology Co., LTD. recognizes that "Information Gain" in this sector comes from understanding the metallurgy, the thread-rolling precision, and the heat treatment processes that ensure 100% reliability. Our integration of automated cold-heading and CNC machining allows for the production of screws with exceptional length-to-diameter ratios, maintaining straightness tolerances that are essential for automated assembly lines.
Moving toward 2025, our technical roadmap focuses on zero-defect thread rolling for screws exceeding 300mm. By utilizing advanced multi-die cold heading machines, we reduce material waste while increasing the fatigue strength of the screw neck, a common failure point in long-form fasteners.
The future of metal screws lies in environmental resistance. We are transitioning from traditional zinc plating to Zinc-Nickel alloy and Geomet/Dacromet coatings, providing over 1,000 hours of salt spray resistance (SST) without compromising dimensional accuracy.
Implementation of AI-driven optical sorting machines ensures that every OEM long metal screw dispatched from our Zhejiang factory meets the exact pitch, straightness, and tensile strength required for aerospace and high-voltage electrical applications.
Zhejiang Jifeilong Instrument Technology Co., LTD. is strategically located in the Oujiang Port area of Wenzhou, a global hub for hardware and electrical components. This geographical advantage provides us with unparalleled supply chain resilience. Our "In-House" ecosystem—from raw material sourcing to automated grinding and heat treatment—minimizes lead times and shields our global clients from market volatility.
Formerly Yueqing Feilong Instrument Factory, we have evolved from a local workshop to a high-quality global supplier. Our philosophy—"Quality First, People-Oriented"—is backed by 25 years of empirical data and thousands of successful industrial implementations.
Long metal screws are used to secure high-capacity battery modules and EV charging pile connectors, where thermal expansion and electrical insulation are critical factors.
In large-scale solar farms, our fasteners provide the depth and corrosion resistance needed to anchor tracking systems in diverse soil and weather conditions.
Specifically designed for molded case circuit breakers (MCCBs), our screws and shafts ensure structural integrity during high-voltage surges.
Precision-ground long screws facilitate the assembly of complex heat exchangers and filtration equipment where space is restricted but reach is required.
We strictly implement national and international quality standards, including ISO 9001 and RoHS compliance. This ensures that every component shipped to Europe, North America, or Southeast Asia meets local safety regulations and industrial codes.
Our technical team provides 24/7 localized support, offering engineering consultations via video conference to resolve design challenges in real-time. Whether you need a specific head style (Torx, Hex, Pan) or a custom thread pitch, our OEM services are tailored to your local market needs.
