High-performance components certified to international standards (DIN, ISO, ANSI).
Established in 2015, Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. has emerged as a titan in the global fastening industry. Located in the heart of China's fastener hub, we leverage decades of regional expertise combined with modern Industry 4.0 manufacturing processes. Our commitment transcends simple supply; we provide comprehensive mechanical integration solutions for the world's most demanding sectors.
As a reputable fastener manufacturer, we have invested heavily in advanced cold-heading machines, automated threading lines, and an in-house heat treatment facility that ensures every bolt and screw—from standard DIN6921 flange bolts to customized 12.9 grade high-tensile components—meets the rigorous demands of modern engineering.
Pioneering the next generation of fastening technology through material science and digital integration.
Development of fasteners with integrated tension sensors for real-time structural health monitoring in bridges and aerospace applications.
Transitioning from traditional hexavalent chromium to advanced Trivalent Zinc and Geomet coatings for superior corrosion resistance and ESG compliance.
Refining Grade 14.9 and titanium alloy screws to meet the lightweight requirements of the Electric Vehicle (EV) and Renewable Energy sectors.
Tailored fastening hardware for critical infrastructure and global manufacturing.
Hot-dip galvanized bolts and solar-specific mounting screws designed for 25-year lifespans in harsh outdoor PV installations.
Precision flange nuts and high-torque bolts (Grade 10.9/12.9) that ensure vibration resistance in drivetrain and chassis assemblies.
Heavy-duty carriage bolts and structural washers for high-rise steel frames, bridge building, and rail transport networks.
Leveraging Hebei's industrial ecosystem for unmatched efficiency and resilience.
Located in Handan, the "Fastener Capital of China," Dongshuo Fastener Manufacturing benefits from a vertically integrated supply chain. This geographical advantage allows us to source raw materials (High-quality carbon steel and alloy steel) within a 50km radius, reducing lead times and carbon footprints. Our "Factory 4.0" initiative integrates AI-driven quality control where high-speed cameras inspect every thread and surface finish, ensuring a zero-defect rate for bulk exports.
Supply Chain Resilience: During global logistics fluctuations, our strategic buffer stock and proximity to major ports like Tianjin and Qingdao ensure that our international clients receive their shipments without the delays common in other regions. We don't just sell screws; we provide supply chain security.
Navigating global standards is our core expertise. Whether your project requires DIN (Deutsches Institut für Normung), ASTM (American Society for Testing and Materials), or ISO compliance, our technical team ensures every product is accompanied by Mill Test Reports (MTR) and Certificates of Conformity.
From LCL (Less than Container Load) for specialized projects to FCL (Full Container Load) for global distributors, our capacity scales with your growth.
Utilize our R&D lab to create bespoke fastener designs. We can open new molds and produce prototypes within 7-14 days.
We provide comprehensive insurance and secure payment terms (T/T, L/C) to mitigate international trade risks.
Expert insights into fastener selection, manufacturing, and logistics.
A "Top Supplier" like Dongshuo is defined by three pillars: manufacturing depth (owning the factory, not just trading), quality certification (ISO 9001:2015), and the ability to provide "Information Gain"—offering technical advice on material selection and coating types based on the end-user's environmental conditions.
Grade 8.8 is a high-tensile bolt usually made of medium carbon steel, suitable for general machinery. Grade 12.9 is made of alloy steel and offers the highest tensile strength (1220 MPa), used for heavy-duty applications like engines and hydraulic systems where failure is not an option.
Yes, we provide free samples for standard items. For specialized customized products, we charge a small mold/sample fee which is refundable upon the placement of a bulk order. We encourage rigorous testing to verify our quality.
We offer a variety of treatments: Electric Galvanizing (Zinc), Hot-Dip Galvanizing (for outdoor use), Blackening (for oil-resistant mechanical parts), and Yellow Zinc plating. Each is tested via Salt Spray Testing (SST) to ensure it meets the required hours of corrosion resistance.
Our factory is located in Handan City, Hebei Province, China. You can fly directly to Handan Airport (HHD). We provide airport pickup and a full tour of our production and QC facilities.
