Established in 1995, Wenzhou Fangyuan Metal Button Co., Ltd. has developed into a premier global manufacturer specializing in the engineering, design, and export of premium metal fasteners. Strategically located in Qiaotou, Wenzhou—widely recognized as China's largest button and garment accessory manufacturing hub—our production facility is built on a 30 mu (approx. 16 acres) campus.
With an operational workforce of over 500 skilled professionals, including 90+ advanced engineers and technical design specialists, our facility manages automated stamping, die-casting, chemical plating, and mechanical sorting processes under one roof. We possess independent import and export licenses, which facilitates direct B2B shipments to customers in Europe, the Americas, Southeast Asia, and the Middle East.
Bronze and brass eyelets (commonly referred to as steam eyes or metal grommets) are critical structural components used to reinforce pre-punched holes in various fabrics, leathers, and technical materials. They prevent unraveling, wear, and structural failure under high-tension loads.
We source premium copper, brass wire, and stainless steel alloys. Our copper-zinc alloys exhibit excellent cold-working ductility, which helps prevent radial splitting when set with high-speed automated pressing machinery.
Raw brass develops a protective patina when exposed to environmental oxygen. For demanding applications, we apply electroplated coatings (nickel-free, gold, black nickel, and antique bronze) that pass strict 24-to-48-hour salt spray testing.
We supply a wide range of standard sizes, with inner diameters spanning from 3mm to over 25mm. Our eyelets are engineered to fit smoothly into manual, semi-automatic, and fully automatic assembly lines.
| Nominal Size Metric | Inner Diameter (ID) | Outer Flange Diameter (OD) | Barrel Height (H) | Optimal Fabric Punch Size |
|---|---|---|---|---|
| FY-03 (Miniature Series) | 3.2 mm | 6.0 mm | 4.0 mm | 3.0 mm - 3.2 mm |
| FY-05 (Utility Spec) | 5.5 mm | 9.5 mm | 5.2 mm | 5.3 mm - 5.5 mm |
| FY-08 (Apparel Standard) | 8.0 mm | 14.0 mm | 6.0 mm | 7.8 mm - 8.0 mm |
| FY-12 (Heavy-Duty Luggage) | 12.0 mm | 21.0 mm | 7.0 mm | 11.8 mm - 12.0 mm |
| FY-15 (Industrial Canvas) | 15.2 mm | 27.5 mm | 8.2 mm | 15.0 mm - 15.2 mm |
| FY-20 (Technical Geotextile) | 20.5 mm | 35.0 mm | 10.5 mm | 20.0 mm - 20.3 mm |
Modern industrial design requires fastening hardware to serve as both structural supports and visual accents. Our brass eyelets, snaps, adjustment buckles, and suspender attachments are engineered to meet these dual requirements across several main target markets:
In high-wear shoe eyelets, our brass hardware withstands repeated friction from laces without losing its shape. This reliability prevents structural tearing in leather, canvas, and synthetic uppers.
Our through-hole jeans buttons, rivets, and heavy-duty snaps are engineered to survive repeated industrial washing cycles, stone washes, and chemical enzyme washes without corroding or losing color.
Designed for harsh environments, our marine-grade corrosion-resistant brass grommets maintain their structural integrity when exposed to humidity, rain, and saltwater environments.
Purchasing directly from Wenzhou Fangyuan Metal Button Co., Ltd. provides global brands, garment factories, and distribution companies with significant cost and logistics advantages:
In today's consumer landscape, safety and environmental compliance are paramount. Leading global retailers require all metal hardware to be free of harmful chemical residues.
Our manufacturing processes and finished products are certified for safe contact with sensitive skin, including babywear. Our materials are completely free of nickel, lead, and heavy metals.
We implement standard quality control inspections at every stage of production, from raw material inspection to final tension testing of completed shipments.
We utilize eco-friendly water treatment and recycling systems to reduce the environmental impact of our electroplating and metal finishing processes.
We also ensure complete compliance with EU REACH and US CPSIA regulations. We conduct routine laboratory testing for lead content, nickel release rates, and pull strength. Test reports can be provided to clients on demand to support your customs clearance and product safety audits.
Every brand has unique design and functional requirements. Wenzhou Fangyuan Metal Button Co., Ltd. offers comprehensive OEM and ODM support to bring your hardware concepts to life:
We can engrave or emboss logos directly onto the flange of eyelets or the faces of jeans buttons using precision CNC tooling.
We offer custom color matching, including antiqued, matte, satin, or high-gloss paint and plated finishes.
We can adjust the length of eyelet barrels to secure materials ranging from paper-thin fabrics to multi-layer leathers.
We calibrate all eyelets to ensure compatibility with high-speed pneumatic and mechanical setting machines, helping to prevent production line jams.
Brass is highly ductile, meaning it rolls or flares smoothly during installation without split rims. It is also naturally resistant to rust, making it ideal for garments that undergo repeated laundering or exposure to moisture. In contrast, iron eyelets will eventually rust and stain fabrics once their outer plating is scratched or worn away.
For standard iron-based hardware, our MOQ is 50,000 pieces. For higher-end brass and stainless steel hardware, the MOQ is 20,000 pieces per run. Smaller trial orders can occasionally be processed if we have matching raw materials in stock.
We use specialized copper and alloy bases that contain no elemental nickel. Our electroplating finishes utilize acid copper and nickel-free tin-cobalt plating processes. We test our products using dimethylglyoxime (DMG) testing protocols to ensure nickel release rates remain well below 0.5 µg/cm²/week, in compliance with EN 1811 standards.
Yes. We manufacture our eyelets and washers to strict tolerances (+/- 0.05mm). This precision ensures smooth feeding through automatic pneumatic or electric eyelet setting machines, preventing misfeeds and reducing production downtime.
The barrel length of the eyelet should exceed the compressed thickness of the material by 1.5mm to 2.0mm. This extra length provides enough material to form a clean, secure roll or star setting on the underside of the washer.
