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.
In the high-stakes world of heavy industry, the humble bolt serves as the literal "joint" of economic progress. For the Republic of Korea—a global powerhouse in shipbuilding, automotive manufacturing, and semiconductors—the demand for high-integrity fastening solutions has never been more critical.
South Korea’s industrial strategy is built on the "Chaebol" ecosystem and a vast network of Tier-1 and Tier-2 suppliers. From the massive shipyards of Ulsan to the high-tech automotive plants in Gwangju, the requirements for bolts (industrial fasteners) are extremely stringent. Korean enterprises prioritize KS (Korean Standards) and ISO/DIN standards to ensure structural longevity under extreme conditions, such as maritime corrosion or high-speed vibration in rail systems.
While Korea maintains a high level of domestic production, the global supply chain has shifted toward a model of "Strategic Sourcing." Chinese factories, particularly those located in Handan (the Fastener Capital of the World), offer an unparalleled Information Gain through massive economies of scale and rapid R&D cycles. By sourcing from specialized Chinese factories like Dongshuo, Korean industrial buyers achieve a 30-40% cost optimization without sacrificing the metallurgical integrity required for Grade 8.8 or 10.9 fasteners.
Our facility in Handan utilizes automated multi-station cold heading machines and continuous heat-treatment lines. This allows us to produce millions of DIN 6921 Flange Bolts or DIN 934 Nuts with a dimensional tolerance of +/- 0.01mm. This efficiency is why we can serve as a primary "Bolt Factory serving Korea," bridging the gap between high-volume manufacturing and precision engineering.
Customized Korean-specification bolts designed and sampled within 7 days using advanced CAD/CAM modeling.
Specialized Geomet, Dacromet, and Hot-Dip Galvanizing to withstand the salty air of Korean coastal shipyards.
Strategic logistics pipelines ensuring that Seoul, Busan, and Incheon industrial zones receive just-in-time (JIT) delivery.
The industry is moving toward Smart Fasteners equipped with IoT sensors to monitor torque tension in real-time. Furthermore, "Green Fasteners"—produced with recycled steel and eco-friendly electroplating—are becoming a requirement for Korean companies adhering to strict ESG (Environmental, Social, and Governance) mandates. Our factory is at the forefront of this transition, implementing closed-loop water systems and energy-efficient induction heating.
International procurement managers from Samsung, Hyundai, and Daewoo-related supply chains require more than just a product. They require Traceability. Every batch from our factory comes with a Material Test Report (MTR) and a certificate of compliance. We understand the "User Intent" of a procurement officer: minimizing risk and maximizing uptime.
The global fastener market is projected to reach $110 Billion by 2030. Korea's share is growing in the electric vehicle (EV) sector. We are pivoting our production lines to offer specialized Black Zinc Oxide CSM Bolts and Nylon Lock Nuts specifically for EV battery pack assembly.
Region Served: South Korea (Busan, Seoul, Incheon, Ulsan, Daegu)
Key Industries: Automotive, Marine, Construction, Tech.
Expert insights for Korean and Global industrial buyers.
Yes. While we primarily manufacture to DIN, ISO, and ANSI standards, we are fully equipped to produce fasteners that meet KS B 1002 (Hexagon Bolts) and KS B 1012 (Hexagon Nuts) specifications. Our technical team can review your specific Korean project blueprints to ensure 100% compliance.
Due to our proximity to major Chinese ports like Tianjin and Qingdao, shipping to Busan or Incheon typically takes only 3-5 days via sea freight. We offer DDP (Delivered Duty Paid) or CIF terms to simplify the import process for our Korean partners.
Every production run undergoes rigorous testing: tensile strength testing, Rockwell hardness testing, salt spray testing (for galvanized coatings), and thread go/no-go gauge checks. We provide full traceability from the raw steel wire to the finished product.
Absolutely. We specialize in custom tooling. If your equipment requires non-standard dimensions or unique head markings (including Korean brand logos), we can open new molds and provide pre-production samples for confirmation.
For standard DIN/ISO items, our MOQ typically starts at 500kg to 1 ton per size. For custom orders, the MOQ depends on the technical complexity, but we always strive to support our customers' growth phases with flexible scaling.
