Engineered for Durability, Precision, and Extreme Performance
VLC stands at the forefront of the fastener industry as a leading bolts and screws manufacturer in China. With nearly two decades of intensive expertise in fastener production and technological innovation, we have established a robust manufacturing infrastructure. Our state-of-the-art facility boasts an annual output of 10,000 tons of high-quality bolts, studs, and screws, specializing in heavy-duty hex bolts and structural components.
Our journey began in 2006, founded with a clear mission: to become the preferred choice for global enterprises seeking reliable fastener manufacturers in China. Today, we bridge the gap between complex industrial requirements and precision engineering.
Innovating for the Future of Infrastructure and Tech
The global industrial fastener market is witnessing a paradigm shift. As industries like renewable energy, electric vehicles (EVs), and smart infrastructure expand, the demand for high-precision, specialized bolts has reached an all-time high. No longer just simple joining components, modern bolts are engineered to withstand extreme pressures, corrosive environments, and high-frequency vibrations.
Integration of AI and automated CNC machining ensures zero-defect production, meeting the stringent tolerances required by aerospace and automotive sectors.
Solar and wind installations require weatherproof, high-strength fasteners (like Grade 8.8 Hex Bolts) capable of lasting 25+ years in outdoor conditions.
Lightweighting is key. We provide high-strength aluminum and stainless fasteners that reduce vehicle weight while ensuring maximum safety.
As a premier exporter of bolts in China, we have adapted to these trends by diversifying our material science—incorporating ASTM A193 B7 alloy steel, Scm440, and 42CrMo4 to handle high-stress applications in oil, gas, and heavy machinery.
From Raw Material to Precision Finished Product
Our CNC center handles complex geometries and non-standard specifications with micron-level accuracy.
Automated lathe processes for consistent internal and external threading across high-volume orders.
Optimized for mass production of standard fasteners while maintaining strict quality control protocols.
For international buyers, sourcing from a Chinese bolt factory is no longer just about cost—it is about supply chain resilience and technical partnership. Global enterprises in the US, Europe, and Southeast Asia require "localized" solutions. We provide customized labeling, specific material certifications (MTRs), and compliance with international standards like ASTM, DIN, ISO, and JIS.
Whether it's ASTM A394 knurled bolts for communication towers in North America or DIN580 eye bolts for marine logistics in the Port of Rotterdam, we understand the local application scenarios that drive your business. Our logistics team ensures that every ton of fasteners is packed in moisture-proof PE bags and heavy-duty cartons to survive long-haul sea freight.
High-Strength Components for Critical Applications
Choosing the right bolts factory in China is critical for the safety and longevity of your projects. At VLC, we combine decades of manufacturing "experience" with deep "technical expertise" to deliver fasteners that exceed expectations. Our commitment to "authority" in the field is backed by our massive 10,000-ton capacity and our "reliability" is proven by a history of successful global exports since 2006.
From the smallest precision CNC-machined aluminum screw to the massive heavy-duty U-bolts used in bridge construction, we treat every order with the same rigor. We invite procurement managers and engineering firms to contact us for customized fastener solutions that drive industrial progress. Our products, ranging from ASTM A193 B7 studs to automotive rivet nuts, are designed to keep the world moving securely.
