Are Brass Eyelets the Right Choice for Your PCB, Paper, or Fabric Application?

A hole in any material is a potential failure point. Without reinforcement, edges fray, tear, or crack under stress. Brass eyelets solve that problem by creating a durable, smooth-surfaced opening that protects the base material and provides a reliable passage for cords, wires, or fasteners. At Nuote Metals, we manufacture eyelets in C2680 yellow brass—a higher-zinc alloy that offers increased hardness and wear resistance compared to standard C2600.

This guide covers the practical decisions: what the technical specifications mean, what finishes are available, and how to avoid common field failures.

Material Grade – C2680 Yellow Brass

We manufacture all brass eyelets from C2680 yellow brass (64–68.5% copper, balance zinc). This alloy offers:

C2680 offers good machinability, ductility, and deep drawing properties. It is easy to electroplate or paint and has good corrosion resistance.

Technical Specifications – Shank Diameter & Outer Diameter

The two most important dimensional parameters for a brass eyelet are shank diameter (the barrel that goes through the hole) and outer diameter (the flange that sits on the surface). We produce eyelets in a wide range of standard sizes.

Standard Size Range

Tolerances

We produce eyelets from shank diameter 0.8 mm up to 10 mm. Custom sizes are available upon request.

Configurations – Standard, Shoulder, Double Head, and Twin

We manufacture eyelets in four main configurations. Each serves a different purpose.

Type	Description	Best For	Image
Standard (Flat Flange)	One-piece, flange on one side only	General hole reinforcement: fabric, canvas, paper, upholstery
Shoulder (Stepped)	Barrel with a stepped profile, acts as a spacer between layers	Multi-layer materials, PCB standoffs, applications requiring a controlled gap
Double Head	Finished flange/head on both sides of the barrel	When both sides need a clean appearance—high-end leather goods, reversible garments
Twin Eyelets	Two parallel eyelets connected at the base or formed as one piece	Dual lacing, parallel wiring, specialized strap systems

Our recommendation: Use standard for most applications. Use shoulder when you need a spacer between layers. Use double head when both sides are visible. Use twin when you need two perfectly aligned holes.

Surface Finishes – From Standard to Premium

We offer a wide range of finishes to suit different functional and aesthetic requirements. All finishes are RoHS compliant.

Two Real-World Applications

These cases are drawn from our production records.

PCB Grounding and Component Mounting (Tin-Plated Brass Eyelets)

Problem: A power supply manufacturer needed a reliable, solderable connection point on double-sided PCBs. Standard through-hole pads were lifting under thermal stress, and the board required a mechanical anchor for heavy transformers.

Our Solution: We supplied tin-plated C2680 brass eyelets with a 2 mm shank diameter. The eyelets provide both mechanical reinforcement (preventing copper foil peeling) and a conductive pathway. The tin plating ensures excellent solderability and low contact resistance.

Result: The eyelets created permanent, low-resistance connection points that withstand 1,000+ thermal cycles. The manufacturer now specifies our PCB eyelets across their entire product line.

Paper Hang Tags and Product Labels 

Problem: A retail brand needed a premium finishing touch for their product hang tags. The tags had a punched hole for attaching to garments, but the hole edges frayed and tore during handling. Standard paper eyelets from craft stores were too thin and inconsistent.

Our Solution: We supplied C2680 brass eyelets with a 3 mm shank diameter in a polished, lacquered finish. The eyelets reinforce the punched hole, preventing tearing and adding a professional, durable appearance.

Result: The brand now uses these eyelets on over 2 million hang tags annually. The eyelets maintain a consistent finish through shipping and handling, and the reinforced holes never tear.

Quality and Transparency

Nuote Metals operates with full traceability and documented quality systems. Our production records show over 50 million brass eyelets shipped in the past five years, with field returns below 0.02%.
