Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. 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.
In the modern industrial landscape, "Anchor Nuts" are no longer simple hardware components; they are critical nodes of mechanical integrity. Dongshuo Fastener Manufacturing is at the forefront of this evolution, transitioning from traditional cold-heading processes to AI-enhanced precision manufacturing. Our technology roadmap focuses on three core pillars: Material Science, Coating Resilience, and Dimensional Accuracy.
Utilizing high-carbon steel, alloy steel, and SUS304/316 stainless steel. Our Grade 8.8 and 10.9 fasteners undergo rigorous heat treatment to ensure tensile strengths exceed ISO 898-1 standards.
From Black Phosphating for interior drywall stability to Hot-Dip Galvanizing (HDG) for marine environments, our coatings provide up to 1000 hours of salt spray resistance.
Implementing CNC machining and multi-station cold forging to achieve thread tolerances within 6g/6H levels, ensuring seamless assembly in automated production lines.
Located in Handan, the "Fastener Capital of China," our facility leverages localized raw material sourcing and advanced logistics to offer unparalleled efficiency.
Every batch is assigned a unique QR code tracking its journey from the steel mill to the final packaging, ensuring full traceability for aerospace and automotive clients.
Proximity to Tianjin Port and Qingdao Port allows for optimized shipping costs and reduced carbon footprints during international transit.
Our "Green Factory" initiative uses closed-loop water recycling and eco-friendly electroplating processes to meet the strictest global ESG criteria.
Dongshuo’s Galvanized Union Bolts and Nylon Lock Nuts are specifically designed to withstand the vibration and thermal expansion typical in photovoltaic mounting structures.
High-tensile DIN 912 Socket Head Bolts provide the security required for powertrain assembly and battery housing in the rapidly growing Electric Vehicle sector.
Our rust-resistant drywall nails and carriage bolts (DIN 603) form the backbone of modern residential and commercial architecture globally.
Navigating the complex world of international standards is a core competency at Dongshuo. We provide full documentation support including MTRs (Mill Test Reports), ISO 9001:2015 certifications, and CE marking for the European market. Our team specializes in bridging the gap between China’s manufacturing power and local project requirements in the USA (ASTM/ANSI), Germany (DIN), and Japan (JIS).
For large-scale industrial buyers, the total cost of ownership (TCO) is determined by more than just the unit price. It involves reliability, lead time, and technical support. Dongshuo Fastener provides a dedicated Key Account Management system that offers:
We maintain stock levels for standard DIN parts to ensure "Just-in-Time" delivery for our long-term partners.
Our engineers provide CAD drawings and material selection advice during your product's R&D phase.
Supporting multiple currencies including USD, EUR, and RMB to simplify international transactions.
Our technical team is standing by to assist with specifications, volume pricing, and logistics planning.
