Engineered for durability, our top line features advanced anti-loosening designs and high-tensile carbon steel processing optimized for Antwerp's industrial sector.
Antwerp represents the economic beating heart of Europe, combining the monumental throughput of the Port of Antwerp-Bruges with complex chemical clusters and critical transport manufacturing lanes. In this demanding high-humidity, marine-adjacent, and highly automated industrial environment, structural integrity is non-negotiable. Standard fasteners fail due to accelerated oxidation, chemical attack, and mechanical fatigue. VLC’s heavy-duty carbon steel fastening solutions are engineered to withstand these precise conditions.
Whether deployed in localized automotive chassis assembly, structural port equipment, maritime transport containers, or heavy conveyor logistics pipelines, our custom and standards-compliant fasteners ensure structural continuity. Our advanced mechanical coatings, including hot-dip galvanizing (HDG), electro-galvanization with blue/yellow passivation, and black oxide treatment, provide exceptional anti-corrosive performance under extreme chemical and salty air exposure.

From automotive powertrain integration to high-vibration logistics conveyors, our fasteners serve critical macro-industry application zones worldwide.
For the Antwerp petrochemical cluster, we offer zinc alloy electroplating and proprietary topcoats that survive over 720 hours of salt spray testing (ISO 9227) without white or red rust.
Critical structural bolts and studs are cold-forged using controlled carbon steel alloys, optimizing yield strength and load retention under continuous heavy cyclic loads.
Designed for automated automotive assembly lines, our unique thread lock profiles and anti-rotation designs eliminate the risk of structural relaxation under mechanical vibration.
Our heat-treatment and baking processes for high-strength steel fasteners strictly control hydrogen entry during electroplating, avoiding unexpected catastrophic stress-corrosion cracking.
Synchronized logistics mapping to critical automotive assembly nodes across Western Europe, ensuring standard parts like DIN 933 and custom L-bolts are delivered directly to production cells.
Leveraging continuous technical investment since 2006 to provide industrial buyers with unparalleled expert design support, custom drawing review, and rapid-response prototyping.
VLC is a premier bolts and screws manufacturer in China. Armed with 20 years of technical expertise in fastener production, we maintain an annual output of 10,000 tons of hex bolts, structural bolts, and studs.
Our History & Commitment: Founded in 2006 with a core mission of becoming the global customer’s first-choice fastener manufacturer, VLC has scaled its operations to cover advanced cold forging, heat treatment, multi-station automatic threading, and precision lathe engineering. We handle every step of production in-house to guarantee structural reliability and absolute dimensional fidelity for custom and standard heavy-assembly fasteners.
These heavy-duty carbon steel fastening components are optimized for structural connection, logistics wear prevention, and machinery anchoring.
From port logistics machinery to specialized automotive assembly, our carbon steel fasteners are optimized for specific regional stresses.
High-tensile Grade 10.9 & 12.9 carbon steel fasteners secure subframes, engines, and heavy suspension joints. Passivation coatings resist chemical degradation and road salts, assuring long-term structural resilience.
Heavy-duty wedge anchors and structural washers secure heavy gantry rails, cranes, and logistics sorting structures at the Port of Antwerp. These parts survive severe mechanical stress and marine air moisture.
Specially designed heavy-duty belt splicing fast-install bolt fasteners are engineered to handle continuous tensile pulling force and wear-resistant friction during long-term materials handling.
As the automotive and chemical manufacturing sectors in Europe embrace clean production, VLC is driving the development of green mechanical joining components. We are actively shifting our surface finish systems to eliminate hexavalent chromium (CrVI) entirely, complying with REACH and RoHS standards.
Additionally, our R&D roadmap focuses on lightweight alloy combinations, precision micro-threading to support automated robotic assembly, and advanced smart fasteners with integrated structural tension tracking.
Our goals are aligned with European OEM initiatives, offering reduced carbon footprints in manufacturing and enhanced longevity that reduces overall material wastage.
Request Compliance CertificationOur manufacturing precision is backed by strict metallurgical testing, ensuring consistency across every production run.

We manufacture high-tensile carbon steel fasteners ranging from Grade 4.8, 8.8, to high-strength 10.9 and 12.9 classes. These grades are optimized for different load-bearing, automotive powertrain, and structural assembly applications.
We apply high-performance protective coatings, including blue zinc plating, yellow zinc galvanization, hot-dip galvanizing, and chemical black oxide treatment. These coatings protect against moisture, salt spray, and oxidation.
Yes, we specialize in custom fastener production using multi-station cold forging and CNC machinery. Customers can provide technical drawings, specifications, or samples to create bespoke thread profiles and head geometries.
For fasteners of Grade 10.9 and higher, we implement post-plating heat baking processes. This releases any trapped hydrogen, ensuring the material remains ductile and free from brittle stress fractures under load.
All our bolts, nuts, and washers conform to internationally recognized standards, including DIN (e.g., DIN 933, DIN 934, DIN 3570), ISO 9001 quality management standards, and European CE/REACH regulations.
