VLC stands as a premier bolts and screws manufacturer in China. With about 20 years of expertise in fasteners production and technology, we have an annual output of 10,000 tons of high-grade bolts, studs, screws, and specialized engineering components, especially hex bolts, structural bolts, and anchor studs. Our factory leader started the first personal-owned business in 2006, with a core mission of becoming customers’ first choice for fasteners manufacturers in China.
In the modern global industrial ecosystem, universal fasteners serve as the invisible backbone of infrastructure, automotive assembly, aerospace, petrochemical plants, and heavy machinery. As international supply chains face dynamic shifts, procurement managers increasingly rely on established Chinese manufacturing hubs that combine cost-efficiency with uncompromising structural integrity. VLC bridges this gap by implementing rigorous metallurgic testing, advanced thread rolling technology, and customized surface treatments to meet ISO, DIN, ASTM, and JIS international standards.
Navigating global trade compliance requires deep expertise in international material certifications and environmental directives. VLC provides complete Material Test Reports (MTR) conforming to EN 10204 3.1 standards, alongside RoHS and REACH chemical compliance verifications. Our engineering support team works closely with overseas distributors and OEM clients to offer localized packaging, barcode labeling, vendor-managed inventory (VMI) forecasting, and rapid prototyping for non-standard fastening requirements.
Universal fasteners are tailored to survive harsh operational environments. Whether deployed in offshore marine platforms requiring corrosion-resistant Delta-coated anchors, high-vibration railway tracks utilizing high-tensile ASTM A193 B7 alloy steel bolts, or precision electronics demanding microscopic CNC-machined micro screws, VLC’s product portfolio delivers fail-safe performance. Our components integrate seamlessly into furniture manufacturing, automotive fuel lines via American-style worm gear hose clamps, and heavy structural building frames.






To sustain our market leadership as a premier universal fasteners supplier, VLC continuously invests in state-of-the-art production machinery and smart factory automation. Our manufacturing floor is equipped with high-precision CNC machining centers, automated high-speed multi-station cold formers, heavy-duty screw cutting lathes, and advanced thread rolling units.

Looking ahead, VLC is pioneering the integration of IoT-enabled optical sorting machines and AI-driven defect detection systems to achieve zero-defect manufacturing. Our R&D division is actively engineering lightweight alloy fasteners and green surface coating techniques that reduce environmental impact while enhancing salt-spray corrosion resistance beyond 1,000 hours, setting new benchmarks for the global fastening industry.
Our fasteners are strictly manufactured in accordance with global benchmarks including ISO, DIN, ANSI/ASME, ASTM, and JIS specifications, ensuring perfect interchangeability and structural reliability across international markets.
Yes. With over 20 years of OEM and ODM experience, we specialize in producing custom non-standard fasteners, micro screws, and specialized machined shafts according to your precise blueprints or physical samples.
Standard catalog items are usually shipped within 15 to 20 days. Custom-engineered production runs typically require 25 to 35 days depending on tooling complexity, raw material availability, and required surface treatments.
Absolutely. Every shipment is accompanied by complete documentation, including EN 10204 3.1 Material Test Reports (MTR), dimensional inspection sheets, and plating thickness verification records upon request.
