Engineered for Resilience: Our Premium Grade 8.8 and Specialized Fastening Portfolio
In the hierarchy of structural fasteners, the Grade 8.8 Bolt represents the industrial benchmark for "High Tensile" performance. As a premier bolt supplier, we recognize that "High Quality" is not a static claim but a metallurgical achievement. Grade 8.8 signifies a tensile strength of 800 MPa and a yield strength ratio of 80% (yielding at 640 MPa).
Based in the heart of China's fastener capital, Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. exemplifies the transition to Factory 4.0. Our 2015 establishment marked the beginning of a specialized journey into integrated production.
Supply Chain Resilience: By centralizing the wire drawing, cold heading, thread rolling, and heat treatment within a localized ecosystem in Handan, we mitigate global supply chain shocks. Our efficiency advantage is passed directly to the client through shorter lead times and competitive Total Cost of Ownership (TCO).
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.
