Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. leverages multi-station cold heading and advanced CNC machining to deliver bolts and nuts with micron-level tolerance. Our commitment to accuracy ensures seamless integration into complex industrial assemblies.
From Carbon Steel 4.8 to Alloy Steel 12.9, and premium Stainless Steel (304/316), we source materials with full traceability. Our internal lab performs tensile testing, hardness checks, and salt spray analysis to guarantee 100% compliance with ISO/DIN standards.
We provide comprehensive solutions across industries, including renewable energy, automotive infrastructure, and heavy machinery. Our supply chain is designed to minimize lead times for global partners while maintaining cost-competitiveness.
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. Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. was established in 2015. It is an enterprise specializing in the production and operation of fasteners.
The global fastener industry is undergoing a paradigm shift toward Smart Fastening and Lightweighting. As a leading manufacturer, Dongshuo is at the forefront of this evolution, focusing on three core pillars:
The integration of IoT in fasteners is no longer a concept but a necessity for critical infrastructure. Future high-quality long bolts will feature integrated sensors to monitor axial tension and preload in real-time, preventing catastrophic failure in bridges and wind turbines.
Beyond traditional galvanization and phosphating, we are researching "Smart Coatings" that provide self-healing properties when scratched. This significantly extends the service life of fasteners in corrosive offshore environments.
Decarbonization is central to our roadmap. We are transitioning to energy-efficient electric furnaces and sourcing recycled steel to lower the carbon footprint of every bolt produced, helping our global clients meet their ESG (Environmental, Social, and Governance) targets.
Specialized high-torque long bolts for wind turbine blade attachment and solar racking systems, designed to withstand extreme vibration and UV exposure.
Lightweight alloy fasteners for electric vehicle chassis and heavy-duty galvanized bolts for the global expansion of charging network grids.
Precision-threaded fasteners with superior shear strength and fatigue resistance, critical for track assembly and rolling stock safety.
High-grade stainless steel and Dacromet-coated bolts engineered for maximum corrosion resistance in saline and subsea environments.
Located in the heart of the "Fastener Capital" — Handan, China — our facility represents the pinnacle of Supply Chain Resilience. By integrating 4.0 manufacturing principles, we offer advantages that transcend simple cost-savings:
"We are not just a supplier; we are a strategic buffer in your global supply chain, mitigating risks and ensuring continuous operation."
Navigating the complexities of international trade requires more than just high-quality products. It requires Trustworthiness and Technical Compliance.
Total adherence to DIN, ANSI, AS, BS, and JIS standards. We ensure that our threads and dimensions match your regional requirements perfectly.
RoHS, REACH, and CE certification support. We provide the documentation necessary to clear customs and satisfy environmental audits in EU and North American markets.
Multilingual technical support and localized logistics coordination. We understand DDP, CIF, and FOB terms to streamline your import process.
A: Our long bolts are manufactured using advanced multi-station cold-heading machines, ensuring consistent thread grain flow and superior mechanical properties. We offer customized length-to-diameter ratios that many standard factories cannot handle.
A: We offer a variety of surface treatments, including Hot-Dip Galvanizing (HDG), Black Oxide, Zinc Plating, and specialized coatings like Dacromet and Geomet. All treatments are verified through ASTM B117 salt spray testing.
A: Yes. We specialize in OEM/ODM services. You can send us your technical drawings or samples, and our engineering team will provide a feasibility analysis, create a mold design, and produce prototypes for confirmation.
A: For stock items, we can ship within 7 days. For custom production runs, lead times typically range from 15 to 30 days depending on the complexity and volume of the order.
A: Yes, we can provide free samples of our standard fasteners. For specialized customized products, we may require a small sample fee which is refundable upon bulk order placement.
