Industry-standard precision components for global industrial infrastructure.
The global rod screw and lead screw market is currently undergoing a seismic shift. As automation, robotics, and high-precision CNC machining become the backbone of modern industry, the demand for high-load-bearing, low-friction fastening solutions has skyrocketed. China, as the world’s manufacturing hub, has transitioned from mass production to "Smart Quality" manufacturing. Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd., established in 2015, stands at the forefront of this transition, combining decades of traditional forging expertise with advanced robotic manufacturing.
Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) ensures that every component—from a standard DIN 912 bolt to a complex rod screw assembly—meets the rigorous demands of the global supply chain. With the emergence of Industry 4.0, we are integrating IoT-ready traceability into our production lines, ensuring that every batch of fasteners is verifiable and reliable for critical infrastructure.
Unlike standard suppliers, Dongshuo Fasteners focuses on Material Fatigue Resistance and Hydrogen Embrittlement Mitigation during the galvanization process. Our screws offer a 15% higher torque threshold compared to industry averages.
Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. was established in 2015. It is an enterprise specializing in the production and operation of fasteners. Our company is committed to providing high-quality fastener products and providing customers with comprehensive solutions in various industries. As a reputable fastener manufacturer, we have advanced production equipment and a professional technical team to meet our customers' needs for different types of fasteners.
Decoding the science of high-strength rod screws and fastening systems.
Utilizing high-speed cold heading technology, we achieve thread tolerances within 6g/6H levels, ensuring seamless assembly in high-vibration environments.
Our coating technologies range from standard Hot-Dip Galvanizing to Geomet and Black Zinc Oxide, providing up to 1000 hours of salt spray resistance.
Looking ahead, we are developing "Smart Screws" with integrated tension sensors for real-time monitoring of bridges and aerospace structures.

How our rod screws power global localized application scenarios.
From dry-wall installation to structural steel bonding, our galvanized flange bolts and drywall nails provide the structural integrity required for modern skyscrapers.
The rise of Electric Vehicles requires lightweight yet incredibly strong fasteners. Our alloy steel socket head bolts (DIN 912) are critical for battery pack assemblies.
Outdoor durability is key. Our Hot-Dip Galvanized double-headed bolts are designed to withstand 25 years of exposure in solar farm environments.
Direct from factory supply for global distributors.
Answering common technical questions for procurement managers and engineers.
A: We are a direct factory (Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd.). Visiting our facility in Handan City, Hebei Province, is highly encouraged to see our advanced cold-forging and quality control labs.
A: The fastener industry is sensitive to carbon steel and alloy steel market fluctuations. We provide real-time quote updates based on current material indexes to ensure transparent EXW pricing.
A: For marine or industrial outdoor use, we recommend Hot-Dip Galvanizing or our specialized Black Zinc Oxide coating, which provides superior rust resistance compared to standard electro-galvanizing.
A: Yes. We can open new molds based on your technical drawings and provide initial samples for tensile testing and dimension confirmation within 7-10 working days.
A: For orders above 1000 USD, we typically require 30% T/T in advance and the balance before shipment. We also accept RMB payments for domestic or specialized trade partnerships.
