VLC is a leading bolts and screws manufacturer in China. With about 20 years of expertise in fasteners production and technology, we have annual output of 10,000tons bolts, studs, screws etc, especially hex bolts, structural bolts and studs.
Our factory leader started the first personal owned business in 2006, with a mission of becoming customers' first choice for fasteners manufacturers in China. Our dedication to OEM Stud Bolts and customized fastening solutions has positioned us as a critical node in the global industrial supply chain.
High-precision manufacturing for non-standard components. Our CNC suite ensures tolerances within microns for critical aerospace and petrochemical applications.
Optimized for high-volume production of stud bolts and screws, ensuring consistent metallurgical integrity and thread accuracy across millions of units.
Specialized equipment for complex threading requirements, including multi-start threads and custom pitch configurations for OEM specifications.
Smart Manufacturing & Industry 4.0: The fastener industry is shifting toward "Smart Fastening." Real-time monitoring of forging temperatures and thread rolling precision through AI sensors ensures that every OEM Stud Bolt meets the highest safety standards before leaving the factory.
Material Science Innovation: As industrial environments become more extreme (deep-sea oil extraction or high-temperature hydrogen energy), there is a surge in demand for exotic alloys such as Inconel, Monel, and Duplex Stainless Steel. VLC is at the forefront, developing proprietary heat-treatment protocols for these advanced materials.
Sustainability & Green Steel: Global procurement now prioritizes the carbon footprint. We are integrating recycled alloy steel and low-emission coating processes (like Eco-friendly Zinc-Nickel) to align with ESG goals of our Fortune 500 partners.
Digital Twin Integration: Future stud bolts will be designed alongside digital twins of the structures they hold, allowing for predictive maintenance and stress analysis before a single piece of metal is cut.
In a volatile market, VLC provides "Just-In-Time" delivery models and localized warehousing support to mitigate logistics risks for European and North American infrastructure projects.
We don't just sell bolts; we provide value engineering. By optimizing the material-to-weight ratio, we help clients reduce shipping costs and installation time, lowering the overall project TCO.
Full traceability is mandatory. Every batch of VLC stud bolts comes with 3.1 Mill Test Certificates, ensuring compliance with ASTM, DIN, JIS, and ISO standards.
By 2030, VLC aims to transition from a traditional hardware manufacturer to a "Integrated Fastening System Provider." Our roadmap includes:
