Standardized machine screws offering highly predictable wear resistance and alignment accuracy.
Optimized for low-friction linear actuators, offering great thermal conductivity and spark-free safety.
Engineered for high soil retention, environmental stress crack resistance, and continuous UV exposure.
Modern industrial design is undergoing a massive transformation. Standard metal components are increasingly being replaced by non-metallic materials and high-precision alloys (such as titanium and brass) in sectors requiring weight optimization, electromagnetic transparency, and unmatched chemical resistance. High-performance polymers, including PEEK (Polyether ether ketone), PVDF, and Reinforced Nylon 66, are no longer considered alternative materials—they are now primary components in critical electrical systems, medical devices, aerospace platforms, and renewable energy grids.
Unlike steel, which is prone to galvanic corrosion, oxidation, and significant magnetic field distortion, engineered polymers provide a suite of unique properties. They offer electrical insulation, thermal stability, resistance to strong mineral acids, and a reduction in component weight of up to 80%. When combined with precision manufacturing methodologies, these materials empower designers to achieve significant "Information Gain" by satisfying multiple strict functional requirements with a single mechanical part.

VLC is a leading 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 bolts, studs, and screws, specializing in hex bolts, structural bolts, and studs. Our factory leader started the first privately owned business in 2006, with a mission of becoming the customer's first choice for fasteners manufacturing in China.
Solving complex environmental and structural fastening dilemmas across dynamic and challenging global industries.
Standard metal brackets installed in solar grids frequently suffer from environmental degradation. Our weatherproof anchors, polymer isolators, and non-corrosive fasteners safeguard photovoltaic configurations against galvanic degradation, intense UV exposure, and wild temperature swings, extending outdoor operational life to over 25 years.
In power transmission stations and EV battery cells, spark avoidance and dielectric resistance are paramount. Our mechanical non-metallic fasteners block stray currents, eliminate short circuit vectors, and replace bulky insulation sleeves with a single integrated polymer fastener, saving assembly volume and streamlining components.
Salt spray is destructive to standard ferrous alloys. Utilizing Marine Grade 5083 Aluminum, titanium alloys, and specialty fluoropolymers, VLC manufactures lightweight rivets and custom fasteners engineered to endure seawater environments, ideal for boat hulls, coastal park infrastructure, offshore platforms, and ship building applications.
Explore our second suite of specialized fasteners, showcasing complex non-standard geometries, specialized non-ferrous compositions, and advanced safety hardware configurations.
Premium grade alloy feedstock optimized for high-precision screw machine processing and dimensional stability.
Durable structural connecting screws designed for clean-line modern modular installations and interior architecture.
High-security mechanical fasteners featuring specialized drive geometry to prevent unauthorized disassembly.
Heavy scaffold coupler engineered to JIS standards for high structural shear resistance and site safety.
Optimized for low weight and structural integrity in saline marine environments.
Engineered castings configured for fast assembly alignment on sheet metal chassis networks.
Quick-service belt splicing buckle set screws designed to minimize factory downtime during repair.
Super-lightweight, ultra-strong titanium fasteners configured for demanding thermal and chemical applications.
For custom non-metallic fasteners, precision is paramount. Standard injection molded polymers can experience thermal contraction during cooling, which can compromise thread precision and torque tolerance. At VLC, we minimize these variations by using precise CNC machining and high-speed automatic lathe processes directly on extruded polymer rods. This method ensures that critical dimensions conform to strict ISO, DIN, and GB standards (such as the GB820 standard used in our oval head machine series).
Our dedicated quality assurance department monitors every batch for structural and dimensional accuracy. By utilizing advanced optical sorting systems, digital tensile testers, and environmental chambers, we check that each non-metallic bolt, structural rivet, and customized nut kit meets its design requirements. Our manufacturing facility has an annual capacity of 10,000 tons, allowing us to supply large-scale projects without sacrificing part-to-part consistency.
In addition, our materials are fully traceable from raw resin to finished fastener, supporting compliance with international environmental standards such as RoHS and REACH. When you specify VLC parts, you are selecting components engineered to minimize failure risks and optimize long-term reliability in the field.
