Established in 2015, Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. has emerged as a titan in the North China fastener hub. Specializing in the high-volume production of "Best Sc Rews" and precision bolts, our facility integrates traditional craftsmanship with modern automation.
Our engineering team focuses on high-torque self-drilling screws and heavy-duty industrial bolts. From Grade 4.8 to 12.9, every product undergoes rigorous mechanical testing for tensile strength, elongation, and surface integrity.
We operate under strict adherence to DIN, ANSI, JIS, and ISO standards. This ensures that our global partners in the UK, USA, Germany, and beyond receive components that integrate seamlessly into their local infrastructure and machinery.
As the Best Sc Rews Manufacturer in China, we aren't just looking at today’s demands; we are engineering for 2030. Our technological roadmap focuses on three pillars of innovation that provide substantial information gain for procurement managers:
Heavy-duty U-bolts and DIN975 threaded rods for skyscraper foundation anchoring and bridge spans. Our products support urban density expansion.
Precision hex bolts and assemblies for chassis systems, where vibration resistance and fatigue life are non-negotiable.
Fasteners for solar panel tracking systems and wind turbine internal housings, treated with high-durability zinc coatings for outdoor exposure.
Why do international firms choose Dongshuo Fastener? It’s our transition into Factory 4.0. Our Handan facility utilizes IoT-connected cold-heading machines that provide real-time data on production efficiency and material wastage.
Supply Chain Resilience: We mitigate global volatility through strategic raw material stockpiling and a vertically integrated production line—from wire drawing to surface treatment—all within one industrial park. This reduces lead times from the industry average of 45 days down to 20 days.
Whether you need DIN934 for European markets or ASTM standards for North America, our manufacturing tolerances exceed international requirements.
We utilize eco-friendly trivalent chromium (Cr3+) plating processes, complying with EU RoHS and REACH regulations to ensure your supply chain is sustainable.
Dedicated logistics teams handle everything from FOB Tianjin to DDP (Delivered Duty Paid) door-to-door services, simplifying your procurement pipeline.
Large-scale industrial procurement requires more than just a low price; it requires a strategic partnership. We offer:
Rapid prototyping from your CAD drawings.
Capacity to handle 100+ container orders monthly.
Vendor Managed Inventory solutions for lean manufacturing.
A: We utilize controlled-atmosphere heat treatment furnaces. Every batch is sampled and tested on a computerized tensile testing machine to ensure it meets the minimum breaking load specified by DIN ISO 898-1.
A: Zinc Plating (Electro-galvanizing) offers a smooth, bright finish suitable for indoor use with moderate corrosion resistance. Hot-Dip Galvanizing (HDG) creates a much thicker layer of zinc-iron alloy, providing 50+ years of protection in harsh outdoor or coastal environments.
A: Yes. Our CNC machining and custom cold-heading department specializes in "Best Sc Rews" designs that don't fit standard DIN/ISO profiles. We can open new molds within 7-10 business days.
A: We operate a "Quality First" policy. If any batch fails to meet the pre-agreed technical specifications upon third-party inspection (SGS/TUV), we offer full replacement or credit, backed by our ISO 9001 quality management system.
A: Typically, we work with a 30% T/T deposit and 70% against the Bill of Lading. For long-term partners, we offer open account (OA) terms and L/C (Letter of Credit) options to facilitate smooth cash flow.
Elevate your industrial assembly with components designed for strength and longevity.
Location: Handan City, Hebei Province, China (The Fastener Capital of the World)
