2mm 真鍮アイレット

In the world of precision fastening, size matters. When applications demand the smallest possible reinforced hole—for delicate fabrics, miniature electronic assemblies, or fine leather goods—2mm brass eyelets deliver the perfect balance of strength and subtlety.

Nuote Metals has manufactured high-quality brass fasteners for over ten years, serving customers across more than 70 countries. Our 2mm brass eyelets are engineered for applications where standard-sized eyelets are simply too large, yet hole reinforcement remains essential.

Follow the below video to know how we make eyelets.

What Are 2mm Brass Eyelets?

2mm brass eyelets are miniature metal rings with a precisely dimensioned 2-millimeter inner diameter. The barrel passes through a punched hole in the material, while the flange sits flush against the surface. When set with appropriate tools, the barrel rolls outward, clamping the material securely between the flange and the expanded tail.

These 2mm brass eyelets serve two primary functions: reinforcement (preventing tear-out and fraying around holes) and aesthetic finishing (providing a clean, professional edge).

Different Kinds of Eyelets We Can Make

Nuote Metals produces different kinds of eyelets, such as brass eyelets, steel eyelets, stainless steel eyelets,aluminum eyelets ,copper eyelets and special eyelets.

Technical Specifications of Nuote Metals 2mm Brass Eyelets

All 2mm brass eyelets from Nuote Metals are manufactured from C26000 cartridge brass, containing 68–70% copper and 30–32% zinc. This alloy provides optimal malleability for clean setting while maintaining excellent corrosion resistance.

Why Choose 2mm Brass Eyelets Over Alternatives?

Advantages of Brass

Naturally corrosion-resistant – Unlike plated steel, solid brass 2mm brass eyelets do not rust when the surface wears or cracks

Malleable – Sets cleanly without cracking, even at this miniature scale

Nickel-free option – Hypoallergenic, suitable for skin-contact applications

Aesthetic warmth – The gold-like colour adds decorative value to finished products

Why 2mm?

The 2mm inner diameter is specifically suited for:

Fine cords and threads up to 1.5mm diameter

Miniature rivet-style applications in electronics and jewellery

Delicate materials where larger eyelets would overwhelm the design

Precision paper binding and archival document repair

Real-World Case – LED Car Headlights (Two Models, Two Eyelet Sizes)

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 2mm 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 2mm 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.

Installation Guide for 2mm Brass Eyelets

Proper installation of 2mm brass eyelets requires precision tools and careful technique due to the miniature scale.

Required Tools

Hole punch – 2.1–2.2mm diameter

Eyelet setter – matched to 2mm eyelet dimensions

Setting die or anvil

Hammer or manual press

Cutting mat

Step-by-Step Installation

Mark the hole position – Use a fine marker or pencil to identify exact locations

Punch the hole – Create a clean hole 0.1–0.2mm larger than the eyelet barrel diameter. Do not oversize

Insert the eyelet – Place the barrel through the hole from the front (flange side)

Position the washer – For two-piece eyelets, place the washer over the protruding barrel on the reverse side

Set the eyelet – Position the setting die over the barrel and strike firmly with a hammer or engage the press. The barrel should roll outward, forming a smooth clinch

Common Installation Mistakes to Avoid

Oversized holes – Lead to loose eyelets that spin or pull out

Insufficient setting force – Results in incomplete barrel roll, reducing holding strength

Misaligned die – Causes asymmetrical clinch and potential material damage

Frequently Asked Questions About 2mm Brass Eyelets

Below are the most common technical inquiries received by Nuote Metals regarding 2mm brass eyelets.

Q1: What is the maximum material thickness that 2mm brass eyelets can accommodate? How do I choose the correct barrel length?

A: The maximum material thickness (grip range) for 2mm brass eyelets depends on the barrel length. For our standard barrel length of 3.0–3.5mm, the recommended grip range is 1.0–2.0mm of total material stack. For thicker materials up to 2.5mm, we offer a longer barrel version with 4.0–4.5mm barrel length. As a general rule, select 2mm brass eyelets with a barrel length approximately 1.0–1.5mm longer than your total material thickness. This extra length provides sufficient material for the barrel to roll outward and form a secure clinch. For material stacks thinner than 1.0mm, consider using self-backing 2mm brass eyelets (one-piece design) which require less barrel length. Nuote Metals can supply custom barrel lengths for specific applications—contact our technical team with your exact material stack thickness for a precise recommendation.

Q2: Will 2mm brass eyelets tarnish or discolour over time? How can I prevent this?

A: Uncoated brass naturally develops a patina when exposed to air and moisture. This oxidation may darken the surface or, in humid environments, produce greenish spots (verdigris). This is a cosmetic change and does not affect the mechanical strength of 2mm brass eyelets. To prevent tarnishing, Nuote Metals offers a lacquered finish on our 2mm brass eyelets—a clear protective coating that seals the brass surface and maintains the original colour. For applications requiring long-term appearance retention (e.g., visible garment eyelets, jewellery components), we recommend our lacquered or nickel-plated finishes. For industrial or hidden applications where appearance is not critical, natural brass 2mm brass eyelets are perfectly suitable and more economical. Our nickel-plated 2mm brass eyelets provide a silver-coloured finish that does not tarnish and is also nickel-release compliant for skin-contact safety.

Q3: Can 2mm brass eyelets be used outdoors or in marine environments? Are they saltwater resistant?

A: 2mm brass eyelets offer good corrosion resistance in outdoor environments, but their performance depends on the specific conditions. For general outdoor use (rain, humidity, seasonal exposure), standard brass 2mm brass eyelets perform well and will outlast plated steel alternatives which rust once the coating is compromised. However, for continuous saltwater exposure or coastal marine environments, we recommend additional protection. Nuote Metals can supply 2mm brass eyelets with enhanced coatings, or we can advise on switching to stainless steel eyelets for extreme marine conditions. Standard brass may tarnish and experience surface corrosion after prolonged salt spray exposure (typically beyond 72 hours). For boat covers, marine canvas, or coastal outdoor gear that sees regular saltwater contact, please discuss your specific environmental requirements with our technical team to select the optimal material and finish for your 2mm brass eyelets.

Q4: What is the pull-out strength of 2mm brass eyelets? Can they withstand repeated tension from laces or cords?

A: The pull-out strength of 2mm brass eyelets depends on both the eyelet design and the base material. For 2mm brass eyelets set in medium-weight leather (approximately 1.5mm thickness), Nuote Metals has tested typical pull-out forces of 15–25 kg (33–55 lbs). For woven fabrics such as 600D polyester canvas, pull-out forces are typically 10–18 kg (22–40 lbs), depending on weave density. These 2mm brass eyelets are designed for repeated tension cycles—the rolled barrel creates a mechanical lock that does not rely on adhesive or friction alone. However, for applications subject to very high or shock loads (e.g., climbing equipment, heavy suspension points), we recommend larger diameter eyelets or alternative fasteners. For normal use in shoelaces, drawstrings, lacing, and light cordage, 2mm brass eyelets from Nuote Metals provide reliable, long-lasting performance.
