High-precision fasteners engineered for critical structural integrity.
Established in 2015, Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. has emerged as a titan in the fastener industry. Located in the heart of Chinaโs fastener manufacturing hub, we specialize in high-tensile long nut and bolt assemblies. Our commitment goes beyond manufacturing; we provide integrated engineering solutions for global infrastructure, automotive, and renewable energy sectors.
By leveraging advanced cold-forging technology and precision machining, we ensure every component meets the rigorous demands of DIN, ISO, and ASTM standards.
Our long nut bolt series features Grade 4.8, 8.8, 10.9, and 12.9 carbon steel and stainless steel options. For extreme environments, our Yellow Zinc, Hot-Dip Galvanizing, and Dacromet coatings offer superior corrosion resistance exceeding 500 hours of salt spray testing.
Our Handan facility integrates Industry 4.0 principles, employing automated multi-station cold headers and computerized heat treatment lines. This ensures batch-to-batch consistencyโa critical factor for large-scale infrastructure projects where a single faulty bolt can compromise structural safety.
By controlling the entire process from raw material wire drawing to final surface treatment, we mitigate global supply chain fluctuations. Our proximity to major shipping ports allows for expedited logistics, reducing lead times by up to 30% compared to traditional manufacturers.
We adhere to strict environmental regulations, utilizing closed-loop water recycling and eco-friendly electroplating processes, ensuring your procurement aligns with global ESG (Environmental, Social, and Governance) goals.
Dongshuo is currently R&D testing "Smart Bolts" embedded with RFID tags for lifecycle tracking and maintenance alerts, essential for bridge and heavy machinery monitoring.
Expansion into lightweight high-strength alloy fasteners to support the burgeoning Electric Vehicle (EV) and Aerospace sectors, focusing on vibration-resistant locking mechanisms.
Custom long bolts and nuts for wind turbine base mounting and solar panel framing, designed to withstand high wind loads and UV exposure.
Providing high-tensile threaded rods and anchor bolts for skyscraper foundations and railway infrastructure, ensuring decade-long reliability.
Corrosion-resistant fasteners for offshore platforms and refinery piping, meeting the highest safety certifications in the oil and gas sector.
