Engineered for excellence, designed for durability
In the vast world of industrial fasteners, the Black Screw occupies a critical position. Known primarily for its black phosphate or black oxide finish, these screws are not merely chosen for their aesthetic "stealth" look but for their specific chemical properties. Globally, the demand for black screws is surging across automotive, aerospace, furniture, and heavy construction sectors. The black coating provides a significant layer of corrosion resistance while maintaining a low-profile appearance, making them the preferred choice for internal machinery and drywall applications.
Today, the market is shifting from traditional carbon steel to high-tensile alloys. As a leading China Black Screw Manufacturer, we observe that global buyers are no longer just looking for the cheapest price; they are seeking reliability, dimensional precision, and environmental compliance in the coating processes.
Our black phosphating process creates a porous layer that holds oil or wax, drastically increasing salt spray test performance compared to standard finishes.
Designed for Grade 4.8, 8.8, and even 12.9 applications, ensuring structural integrity in high-stress industrial environments.
The specialized black coating reduces friction during installation, preventing threads from seizing in automated assembly lines.
The fastener industry is undergoing a "Smart Transformation." As the Best Black Screw Factory in Handan, we are integrating AI and IoT into our manufacturing lines. But what does the future hold for the global market?
Established in 2015, Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. has grown into a cornerstone of the fastener industry. Located in the heart of China’s fastener hub, we specialize in the production and operation of high-performance bolts, screws, and nuts.
Our commitment is simple: to provide high-quality fastener products and comprehensive solutions. With advanced production equipment and a professional technical team, we meet the rigorous demands of modern engineering. Whether it is a custom blackened double-headed bolt or a standard DIN 934 nut, our facility is equipped to deliver excellence at scale.
China's complete industrial chain means we source raw steel, heat treatment, and surface coating services within a 50km radius, drastically reducing lead times.
We produce millions of units daily. This high-volume output allows us to offer the most competitive pricing without compromising on material grade or coating thickness.
Need a specific head style or a non-standard thread pitch? Our engineering team can develop prototypes and move to mass production faster than any Western counterpart.
Black screws are ubiquitous in diverse environments:
We strictly adhere to international standards to ensure our black screws are compatible with global projects. This includes:
