Ningyuan Fastener
Ningyuan Fastener
Engineered for Maximum Pull-out Resistance and Longevity
Handan Ningyuan Fastener Manufacturing Co., Ltd. (formerly Jin Langtao), founded in 2005, is situated in Handan Yongnian—globally recognized as the "Fastener Capital" of China. For nearly two decades, we have evolved from a specialized workshop into a global powerhouse in the production of high-end railway sleeper screws and photovoltaic mounting accessories.
Our philosophy is simple: Development is the direction; hard work is the truth. With over 20,000 square meters of state-of-the-art manufacturing space and a dedicated team of 66 experts, we bridge the gap between traditional engineering and Industry 4.0 efficiency.
Deep Dive into the 2024-2030 Infrastructure Outlook
The global railway industry is undergoing a paradigm shift. With the rise of the European Green Deal and China's "Belt and Road Initiative," the demand for high-speed rail (HSR) has skyrocketed. Railway sleeper screws (also known as rail screw spikes or sleeper bolts) are no longer just basic fasteners; they are critical safety components that must withstand extreme dynamic loads and vibration frequencies. Modern HSR requires screws with superior fatigue resistance and specialized thread designs to prevent loosening over decades of operation.
Advanced metallurgy ensures our screws handle the rapid stress cycles of 350km/h transit systems without structural failure.
Manufacturing to UIC, DIN, and ASTM standards allows our products to integrate seamlessly into international rail networks.
Utilizing Chrome-free Dacromet and HDG treatments to meet stringent environmental regulations in the EU and NA.
We are seeing an increased interest in "Smart Fasteners"—bolts integrated with sensors for real-time tension monitoring. While still in its early stages for general rail use, the trend toward precision-tensioning during installation is already here. As a leading manufacturer, Ningyuan Fastener utilizes high-precision cold-heading and thread-rolling technology to ensure that every screw meets the exact torque-to-tension requirements specified by railway engineers.
Why Handan Ningyuan is the Preferred Partner for Global Procurement
Unlike middleman exporters, we control the entire lifecycle of the railway sleeper screw—from raw wire rod selection (Grade 4.8, 8.8, 10.9) to heat treatment and final anti-corrosion coating. This vertical integration reduces lead times by 30% compared to industry averages.
Our facility is ISO9001 certified, and our products undergo ROHS EU testing and 2000/53/EC ELV testing. We provide full traceability for every batch, ensuring that safety-critical rail components are 100% reliable.
Located in Yongnian, we are at the heart of the world's fastener logistics hub. This provides us with immediate access to specialized steel mills and advanced surface treatment facilities, giving our clients a cost-to-quality ratio that is unmatched globally.
From Alpine Tunnels to Desert Logistics Lines
Railway sleeper screws must perform in diverse climatic conditions. We offer localized optimizations for:
While most manufacturers focus on tensile strength, we focus on Thread Engagement Depth and Anti-friction Coatings. By optimizing the friction coefficient between the screw and the dowel/sleeper, we ensure that installation torque is converted more efficiently into clamping force, reducing track maintenance costs by up to 15%.

Expert insights into Railway Sleeper Screw procurement
The SS series (such as SS1, SS5, SS8, SS25) differ primarily in their length, diameter, and thread pitch. For instance, the SS8 is widely used in European rail networks for timber sleepers, while the SS25 is often paired with plastic dowels in concrete sleepers for HSR. We can manufacture all SS series variations according to UIC 864-1 standards.
We utilize a multi-stage Hot-Dip Galvanizing (HDG) process. After acid pickling and fluxing, the screws are submerged in 450°C molten zinc. This creates a metallurgical bond with the steel, providing cathodic protection that prevents rust even if the surface is scratched during installation.
Yes. For large-scale infrastructure projects, we provide custom head stamping (Project ID, Strength Grade, Manufacturer Logo) to ensure traceability and compliance with local railway authority requirements.
With over 50 sets of production equipment and an annual output of 60 million+ pieces, we can mobilize dedicated production lines for major tenders, ensuring consistent delivery schedules even during peak construction seasons.
Absolutely. We provide free samples for all standard railway sleeper screws. For custom designs, we provide 3D-printed prototypes followed by CNC-machined samples for initial testing before moving to mass production.
