Ningyuan Fastener
Explore our high-performance hexagon head screws, bolts, and specialized structural components engineered for global industrial applications.
Handan Ningyuan Fastener Manufacturing Co., Ltd. (formerly Jin Langtao), founded in 2005, is strategically situated in Handan Yongnian, Hebei Province—widely recognized as the fastener capital of China. For nearly two decades, we have dedicated ourselves to the research, development, and high-volume production of high-end industrial fasteners and photovoltaic mounting accessories.
Our operation has evolved into a modern, integrated manufacturing enterprise. We bridge the gap between advanced metallurgy and structural engineering, providing standard and custom fastener solutions that secure critical infrastructure worldwide. From building electromechanical seismic systems to steel structures and solar energy arrays, our products deliver the reliability that modern engineering demands.
How advanced cold-heading, metallurgical precision, and smart manufacturing are shaping the next generation of high-strength fasteners.
Traditional machining of hexagon screw heads introduces micro-cracks and material wastage. Our production line utilizes multi-station cold heading machines that plastically deform the steel wire at room temperature. This process aligns the grain flow of the metal with the contours of the hexagon head, significantly increasing the shear strength and torque resistance of the finished bolt.
To meet the demands of harsh outdoor environments, particularly in photovoltaic installations, we are transitioning from standard electro-galvanizing to high-durability coatings. Our technical roadmap highlights hot-dip galvanizing (HDG), zinc-nickel alloy plating, and environmental-friendly Geomet coatings. These treatments ensure over 1,000 hours of salt spray testing without red rust, preventing galvanic corrosion in aluminum mounting structures.
Looking to the future, Ningyuan is exploring the integration of smart fastening technologies. By incorporating micro-sensors and specialized head geometry modifications, future hexagon bolts will be capable of transmitting tension and preload data wirelessly. This allows real-time monitoring of structural integrity in high-risk seismic zones and heavy industrial applications.
Ningyuan fasteners are engineered to serve as the structural backbone for global energy, construction, and infrastructure sectors.
We supply complete mounting systems, including C-shaped steel, U-shaped steel, H-rails, press blocks, and hot-dip galvanized hex bolts. Our fasteners are designed to withstand extreme wind loads and thermal expansion in utility-scale solar farms globally.
Our building electromechanical seismic systems, seismic support arms, and earthquake-resistant hangers are engineered to absorb dynamic kinetic energy. They secure HVAC, piping, and electrical conduits against seismic disruptions in high-density urban areas.
High-strength dry wall nails, structural bolts, and custom hexagon head fasteners form the structural framework of modern high-rises and industrial warehouses, ensuring long-term load distribution and joint integrity under static and dynamic loads.
Operating from our 20,000 square meter state-of-the-art facility in Handan, Ningyuan Fastener leverages advanced automated manufacturing to optimize lead times and maintain consistent quality. With over 50 sets of modern production equipment, we manage the entire manufacturing cycle in-house—from raw material wire drawing and spheroidizing annealing to cold heading, thread rolling, and surface treatment.
By integrating ERP-driven production scheduling, we respond dynamically to fluctuating raw material costs and global shipping timelines. Our location in Yongnian provides us with direct access to high-grade steel mills and an established logistics ecosystem, allowing us to export millions of pieces monthly while maintaining highly competitive pricing structures for our international partners.
Our fasteners and structural components are deployed across diverse engineering environments, ensuring safety and structural longevity.
Securing solar panels and racking systems against high wind speeds and environmental degradation.
Providing structural reinforcement for mechanical, electrical, and plumbing systems in commercial buildings.
High-strength bolting solutions for structural steel joints, bridges, and industrial warehouses.
Integrated support systems for underground utility tunnels and heavy-duty industrial piping networks.
Navigating international regulatory frameworks is a core competency at Ningyuan Fastener. We align our manufacturing processes with global standards to ensure seamless integration into your local supply chain. Our quality management system is certified to ISO9001, and our products comply fully with RoHS and ELV (End of Life Vehicles) directives.
For automotive and heavy industrial clients, we strictly adhere to GB/T30512 standards governing banned substances, ensuring that our fasteners meet the environmental and chemical safety requirements of the European Union, North America, and Asia-Pacific regions. We provide complete material test reports (MTRs), plating thickness certifications, and torque-tension test curves with every shipment.
How we streamline the procurement process for international distributors, EPC contractors, and OEM manufacturers.
We manufacture custom hexagon head configurations, thread pitches, and lengths tailored to your engineering drawings. Custom head markings, brand stamping, and specialized packaging are available to support your brand identity.
Equipped with an in-house testing laboratory, we perform tensile strength testing, hardness testing, thread go/no-go gauge inspections, and coating thickness measurements on every production batch to guarantee zero-defect delivery.
Our engineering team provides complimentary technical consultations, helping you select the optimal material grades, thread types, and surface finishes to maximize performance while minimizing project costs.

We manufacture fasteners using a wide range of carbon steels, alloy steels, and stainless steels. This includes medium carbon steel for Grade 8.8, alloy steel for high-tensile Grade 10.9 and 12.9, and corrosion-resistant stainless steel (A2/A4). We also manufacture specialized nylon hexagon socket bolts for electrical insulation and chemical resistance applications.
Yes. We offer a comprehensive range of surface treatments including hot-dip galvanizing (HDG), electro-galvanizing (zinc plating), yellow zinc passivation, black oxide, zinc flake coatings (Geomet/Dacromet), and specialized Teflon coatings. Our hot-dip galvanized fasteners are highly recommended for outdoor photovoltaic brackets and coastal installations due to their superior sacrificial protection.
Our factory has passed the ISO9001 quality management system certification. Our products comply with the EU RoHS directive, the End of Life Vehicles (ELV) directive 2000/53/EC, and the GB/T30512 standard for automotive banned substances. We also maintain strict compliance with municipal research standards for high-end structural fasteners.
Yes, we provide free samples of our regular, standard-sized fasteners (such as standard hexagon bolts, nuts, and self-drilling screws) for quality evaluation and fitment testing. Custom-engineered components may require a tooling fee, which is typically refundable upon bulk order placement.
For standard stock items, we can ship within 7 to 10 working days. For large-scale manufacturing runs or custom OEM orders, our standard lead time ranges from 25 to 40 days, depending on the complexity of the geometry, heat treatment requirements, and surface finish specifications.
