In the hierarchy of mechanical engineering, Grade 8.8 bolts represent the "golden standard" for structural reliability. Classified as high-tensile fasteners under ISO 898-1 standards, these bolts are forged from medium carbon steel and quenched and tempered to achieve a tensile strength of 800 MPa and a yield strength of 640 MPa.
Currently, the global industrial fastener market is projected to reach over USD 120 billion by 2030. Grade 8.8 on bolts serves as the backbone of this market, vital for the automotive, construction, and heavy machinery industries. As infrastructure projects modernize across Europe and North America, the demand for high-strength, corrosion-resistant Chinese fasteners has surged due to their exceptional price-to-performance ratio.
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. Our operations are anchored in the heart of China’s fastener capital, Yongnian, allowing us to leverage a massive industrial cluster for efficiency.
Located in Handan, Hebei, our factory is situated within the world's largest fastener production hub. This provides immediate access to raw steel suppliers, heat treatment specialists, and surface coating facilities (Galvanizing, Black Oxide, Dacromet), reducing lead times by 30% compared to isolated manufacturers.
Modern Chinese factories utilize multi-station cold heading machines and automated optical sorting systems. This ensures that every Grade 8.8 bolt meets exact tolerances, crucial for high-speed assembly lines in the automotive sector.
By producing millions of units per month, we can amortize energy and labor costs, offering global procurement teams a "Direct-from-Factory" pricing model that bypasses expensive middle-layer distributors.
The price is negotiable. It can be changed according to your quantity or packaging. We offer tiered pricing for bulk industrial orders.
We believe in the quality of our 8.8 bolts. Samples are available for testing to ensure they meet your local engineering standards.
All of our products are made of high-quality environmentally friendly materials and meet ISO standards for carbon steel composition.
You can send your own design and logo. We can open new molds and provide custom marking on bolt heads for brand recognition.
The versatility of Grade 8.8 fasteners makes them indispensable across multiple sectors. Our engineers highlight the following key use cases:
The industry is moving away from traditional electro-galvanizing toward Zinc Flake and Dacromet coatings, which provide 1000+ hours of salt spray resistance without the risk of hydrogen embrittlement.
Green manufacturing is no longer optional. Dongshuo Fastener is investing in energy-efficient heat treatment furnaces to reduce the carbon footprint of our 8.8 bolt production.
Global enterprises now demand full traceability. We are implementing QR code-based batch tracking, allowing clients to access material test reports (MTR) instantly.
