Precision Small Brass Eyelets Manufacturer – C2680 & C2600 Brass | Nuote Metals

A hole in fabric, leather, or paper is only as strong as its reinforcement. Without protection, the edges fray, stretch, and eventually tear. Small brass eyelets solve this problem permanently—by clamping the material, protecting the cut edge, and distributing stress across a wide flange. Made from C2680 or C2600 brass, these miniature components offer the ideal combination of corrosion resistance, formability, and aesthetic appeal.

Nuote Metals manufactures small brass eyelets using progressive deep drawing from brass sheet—not from seamed tube stock. This process yields a seamless, burr‑free barrel with consistent wall thickness, ensuring reliable setting and long‑term performance. Our production capacity exceeds 10 million eyelets per day, with diameters ranging from 0.8mm to 10mm.

What Are Small Brass Eyelets?

Small brass eyelets are miniature metal rings used to reinforce holes in lightweight materials. The barrel passes through a punched hole, while the flange sits against the surface. When set with appropriate tools, the barrel rolls outward, clamping the material securely between the flange and the expanded tail.

They serve two primary functions:

Reinforcement – Prevents tearing, fraying, and stretching around holes

Aesthetic finishing – Provides a clean, professional edge with a warm gold appearance

Because they are made from brass, small brass eyelets offer natural corrosion resistance, good electrical conductivity, and a finish that ages gracefully. They are easy to set with a hand press or small machine, and once installed, they stay put without loosening. The small size makes them perfect for delicate items where a larger eyelet would look out of place.

How We Manufacture Small Brass Eyelets – Deep Drawing from Sheet

Unlike punched eyelets (which can leave a rough edge) or tube‑style eyelets (which have a seam), our small brass eyelets are produced using progressive deep drawing from brass sheet. This process yields a seamless, work‑hardened barrel with no seam, no burr, and consistent wall thickness.

Step‑by‑Step Production Process

Material sourcing – Certified C2680 or C2600 brass sheet is purchased from approved mills. Each coil carries a heat number for full traceability.

Incoming material inspection – Every coil is tested with a spectrometer to verify copper and zinc content. Thickness is measured with a laser micrometer. Coils that do not meet our internal standards are rejected.

Progressive deep‑draw stamping – The coil feeds into a transfer press with a multi‑station progressive die. In one continuous, automated sequence, the die:

• Blanks a disc from the strip
• First draw (shallow cup)
• Second draw (deeper cup)
• Third draw (final barrel length)
• Pierces the bottom to create the inner diameter
• Coins the flange flat and parallel
• Separates the finished eyelet from the carrier strip

Tumbling and deburring – Micro‑burrs are removed and the surface is prepared for finishing.

Plating or lacquering – Applied in‑house or by certified partners.

100% optical sorting – Every eyelet is inspected for inner diameter, outer flange, and barrel length.

Our deep‑draw process is fully automated and operates at speeds of 80–150 strokes per minute. We can produce small brass eyelets in diameters from 0.8mm to 10mm, with daily output exceeding 10 million pieces.

Our Quality Control Process – One Eyelet, Eight Checks

We do not rely on random sampling alone. Every batch of small brass eyelets follows a layered inspection system that catches issues before they become problems.

Incoming material stage

Each coil of brass sheet is checked for thickness (±0.02mm) and composition (spectrometer). We reject any coil that deviates from the specified alloy range.

Setup and first‑off stage

When tooling is installed, the first 10 eyelets are examined under 20× magnification for surface defects, then measured on an optical comparator. Inner diameter, outer flange, barrel length, and concentricity must match the drawing before production begins.

During production stage

Operators pull 5 eyelets every 500 pieces. They check critical dimensions with digital calipers and a go/no‑go gauge for inner diameter. Any drift beyond tolerance triggers an immediate press stop and tool adjustment.

Clinch verification stage

Every 2,000 pieces, we set 3 eyelets into a sample of your actual material (leather, fabric, or paper). The rolled clinch is inspected for symmetry, tightness, and crack‑free formation.

Corrosion testing (if applicable)

For plated eyelets, samples are placed in our salt spray chamber per ASTM B117. Nickel plating: 96 hours minimum. A certificate is issued with the batch.

Final sorting stage

Every single eyelet passes through an optical sorting machine with high‑speed cameras. It rejects parts with incorrect inner diameter, outer flange, or barrel length. After sorting, a random AQL sample (Level II, 1.0) is manually verified with profile projector and micrometers.

All inspection records—including measurement logs, test setting photos, and salt spray reports—are retained for five years and are included with every shipment.

One Real Customer Example – LED Car Headlight Assembly

This is one of many applications for small brass eyelets. We include it to show real production use, not to suggest limitation.

A manufacturer of aftermarket LED car headlights needed durable, corrosion‑resistant eyelets for two distinct lamp models. Each model had different assembly requirements, but both demanded consistent quality, resistance to under‑hood heat and vibration, and compatibility with automated production lines.

Nuote Metals supplied two sizes of small brass eyelets in C2680 brass – a higher‑zinc alloy chosen for its increased hardness and excellent formability. Both sizes share the same shank diameter (2mm) and cap diameter (2.5mm), but differ in total length. For the first headlight model, we provided eyelets with a total length of 5mm. For the second model, we supplied the longer version with a total length of 7mm. Both were finished with natural lacquer to prevent tarnishing and ensure surface non‑conductivity.

The LED manufacturer integrated both small brass eyelets into their automated assembly lines. After 3,000 hours of combined thermal cycling (‑30°C to 85°C) and vibration testing, no loosening, cracking, or corrosion was observed across either size. The customer now uses our C2680 brass eyelets as a standard component across multiple LED headlight families.

Applications – Where Small Brass Eyelets Are Used

Small brass eyelets are used across a wide range of industries and applications:

Three Questions We Answer Often

Q1: What is the difference between C2680 and C2600 brass for small brass eyelets? Which one should I choose?

A: C2600 (Cartridge Brass) contains approximately 70% copper and 30% zinc. It offers excellent ductility and is the standard choice for most eyelet applications. C2680 (Yellow Brass) contains approximately 65% copper and 35% zinc – higher zinc content gives it increased hardness and wear resistance. For applications that experience repeated friction – such as belt holes, lacing points, or high‑wear leather goods – we recommend C2680. For general purpose use where maximum formability is required, C2600 is the better choice. We stock both alloys and can advise based on your specific application.

Q2: How do I select the correct barrel length for a small brass eyelet?

A: Select a barrel length 1.0–1.5mm longer than your total material stack thickness. For example, if you are reinforcing 2mm thick leather, choose a barrel length of 3.0–3.5mm. This extra length provides enough material for the barrel to roll outward and form a secure clinch without bottoming out. If the barrel is too short, the clinch will be weak. Too long, and the barrel may crumple. Send us your material thickness, and we will recommend the exact barrel length.

Q3: Can small brass eyelets be used outdoors without tarnishing?

A: Natural brass will develop a patina over time when exposed to air and moisture – this is cosmetic and does not affect mechanical strength. For applications where appearance must be maintained, we recommend our lacquered finish (seals the brass surface, prevents tarnishing for 2–3 years) or nickel‑plated finish (provides a silver appearance and 96 hours of salt spray resistance). For the LED headlight case above, the customer chose lacquered finish to maintain the gold appearance while preventing corrosion under‑hood.
