Explore our high-performance structural fasteners, self-clinching components, and specialized industrial hardware built for extreme reliability.
Two decades of dedicated craftsmanship, stringent quality control, and cutting-edge industrial production capabilities from China's top fastener hub.
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 commitment to rigorous testing protocols, metallurgy optimization, and high-tensile strength verification ensures that every single batch dispatched meets or exceeds international standards such as DIN, ISO, ASTM, and JIS. We empower global supply chains by bridging raw material integrity with advanced automated production.
Utilizing state-of-the-art computer numerical control (CNC) machinery, precision lathes, and automatic multi-station forming equipment.
High-precision turning operations to maintain ultra-tight dimensional tolerances for non-standard custom fasteners.
Advanced automated milling and threading capabilities designed for complex industrial hardware assembly requirements.
Optimized for high-volume mass production without compromising structural integrity or thread pitch precision.
Streamlining production loops to reduce lead times and ensure absolute consistency across large orders.
Every production line is backed by rigorous optical sorting, hardness testing, and salt spray corrosion testing to guarantee ultimate field performance in hostile environments.
From corrosive marine environments to heavy-duty concrete anchoring, discover our specialized chemical, brass, and structural fasteners.
Navigating international industrial landscapes with agile manufacturing, robust material traceability, and comprehensive compliance guarantees.
Our fastener assemblies are engineered for diverse regional environments—ranging from sub-zero offshore oil rigs and high-humidity marine ecosystems to high-vibration automotive assembly lines and heavy commercial construction infrastructure.
Leveraging China's mature industrial ecosystem, we maintain stable raw material reserves, optimized automated production loops, and scalable logistics networks to protect global partners against market volatility and supply disruptions.
Integrating smart IoT monitoring in assembly lines, eco-friendly surface coatings (such as Geomet and advanced PTFE), and carbon-neutral metallurgy to meet tomorrow's stringent global environmental and engineering standards.
Expert answers regarding our manufacturing capabilities, quality compliance, and OEM/ODM partnership processes.
With over 20 years of expertise and an annual output exceeding 10,000 tons, we specialize in high-tensile hex bolts, structural rods, self-clinching PEM fasteners, precision CNC turned parts, and custom non-standard screw components tailored to exact client blueprints.
We strictly adhere to global standards such as DIN, ISO, ASTM, and JIS. Our surface treatment options include Hot-Dip Galvanizing (HDG), Black Oxide, Zinc Plating, Dacromet, Geomet, and FDA-compliant PTFE coatings tested via rigorous salt spray analysis.
Standard production runs typically range from 20 to 35 days depending on material grade, finishing requirements, and volume. Our optimized automated CNC and lathe systems allow for rapid prototyping and efficient high-volume scaling.
Yes. We provide comprehensive export documentation, mill test certificates (MTC), custom packaging solutions, and seamless coordination with global freight forwarders to ensure secure, on-time delivery across over 50 countries worldwide.
