Designed and manufactured to withstand structural stresses and corrosive environments globally.
Founded in 2006, VLC has grown into a leading bolts and screws manufacturer in China, powered by a dedicated mission: to become the premier global choice for heavy-duty metal fasteners. Backed by nearly 20 years of technical expertise, our automated facilities boast an annual production capacity exceeding 10,000 tons of high-grade bolts, studs, screws, and tailored non-standard sheet metal fasteners.
From cold heading to multi-axis CNC machining, we utilize advanced raw material selection, metallurgical verification, and strict dimensional tolerances to deliver high-integrity mechanical joints. Whether you need structural hex bolts or micro screws for precision electronics, VLC delivers absolute reliable engineering.
Delivering high-tensile, anti-corrosive, and vibration-resistant structural locking systems across critical sectors.
High-vibration chassis assemblies, battery pack casings, and precision bracket connectors demand lightweight materials with extreme shear strength. Our custom forgings and CNC milled brackets ensure safety for heavy-duty commercial fleets and EVs.
Outdoor structural fixtures require long-lasting, weatherproof hardware that combats atmospheric corrosion. We supply premium SS304 self-drilling fasteners and heavy-duty M12 bracket anchors designed to last in demanding desert and coastal environments.
Micro mechanical design requires zero defect rates. Our precision micro SEMS screws, customized brass inserts, and aluminum chassis fasteners are crafted for tight clearances, preventing signal interference and structural failures.
Leveraging high-end equipment to meet precise dimensional tolerances and complex custom geometries.
For complex shapes, low-volume pilot runs, or specialized aviation components, our CNC milling centers process aerospace-grade titanium (Gr.5) and tempered aluminum. This guarantees structural integrity and dimensional consistency to within ±0.01mm.
For high-volume production of fasteners, spacer studs, and wood threaded inserts, our Swiss-type automated lathes and screw machines run non-stop. This efficiency ensures quick lead times and competitive pricing without sacrificing quality.
Meeting international engineering standards and ensuring reliable field performance through strict manufacturing control.
We supply full EN 10204 3.1 material certificates for every batch. From C34200 brass, SS304/SS316 stainless steels, carbon steel alloys to Grade 5 Titanium, we track the mechanical properties of our raw materials from mill to finished product.
To resist galvanic and environmental corrosion, we offer premium plating options, including hot-dip galvanizing (HDG), Dacromet, Geomet, zinc plating (yellow/blue/black), nickel plating, and anodized coatings, tested via salt spray test (SST) protocols.
Our fasteners are manufactured in strict compliance with DIN, ISO, ANSI/ASME, JIS, and BS standards. This guarantees trouble-free replacement and reliable thread engagement in automotive assemblies and structural infrastructure.
Engineered for high performance, ease of installation, and robust structural connections.
Innovations driving the future of assembly, materials engineering, and green manufacturing.
As industries shift toward automation, fasteners are evolving. The demand for lightweight, high-strength materials (such as titanium, specialty brasses, and custom nylon composites like UL-certified PA66) is rising rapidly. These materials allow automotive, aerospace, and energy sectors to reduce weight and emissions while maintaining structural strength.
VLC is investing in eco-friendly surface coatings that meet strict global standards, including RoHS, REACH, and California Proposition 65. Our goal is to eliminate hexavalent chromium and heavy metal byproducts from the plating process, providing green, sustainable components for smart infrastructure.
