Eyelet&Grommets
Custom Metal Eyelets and Grommets
Baocheng supplies custom metal eyelets and grommets for apparel, footwear, leather goods, bags, curtains, outdoor textiles, banners, packaging and industrial fabric products. Instead of limiting customers to several fixed retail sizes, we develop eyelets according to drawings, physical samples, material thickness, installation conditions and performance requirements.
Customers can specify the eyelet dimensions, structure, material, color, surface treatment and washer configuration. Special requirements such as low magnetic response, corrosion resistance, nickel release control, decorative appearance and pull-out performance can also be discussed before sampling.
This page presents Baocheng’s custom manufacturing capabilities. For an accurate quotation, customers are encouraged to send a technical drawing, reference sample or detailed dimensional requirements.
Custom Eyelet Sizes 
Eyelet size should not be selected only by the visible flange diameter. The inner hole, barrel diameter, barrel length, washer dimensions and total material thickness all affect installation quality. Baocheng can develop small decorative eyelets as well as larger metal grommets for applications requiring stronger hole reinforcement.
| Dimension | Customization Available | Why It Matters |
|---|---|---|
| Inner Hole Diameter | Customized according to drawing or application | Determines the available space for cords, laces, hooks, straps or ventilation |
| Flange Outside Diameter | Standard round or custom dimensions | Affects visible appearance and the area over which pressure is distributed |
| Barrel Diameter | Matched to the installation hole and setting method | Influences positioning, hole fit and installation stability |
| Barrel Length | Selected according to the total material stack thickness | Insufficient length may prevent complete rolling, while excessive length may cause deformation |
| Material Thickness | Evaluated according to size, material and required strength | Affects forming performance, edge strength, weight and cost |
| Washer Dimensions | Customized to match the eyelet structure | Helps distribute installation pressure and improve support on soft or highly stressed materials |
| Dimensional Tolerance | Defined according to assembly and installation requirements | Supports more consistent setting results during mass production |
To determine a suitable barrel length, customers should provide the total thickness of all fabric, leather, coating, reinforcement and lining layers at the installation position. Baocheng can evaluate dimensional relationships before tooling and sampling.
Eyelet Structures Available for Custom Development

One-Piece Eyelets
One-piece eyelets are commonly used for decorative openings, lightweight garments, tags, packaging and applications with moderate mechanical requirements. They provide a clean appearance and can be developed in different flange and barrel dimensions.
Eyelets With Washers
A washer supports the back of the material and helps distribute setting pressure over a larger area. Washer-backed eyelets are often selected for leather goods, bags, footwear, curtains, tents, banners, covers and other applications exposed to repeated pulling or movement.
Rolled-Rim and Smooth-Edge Eyelets
A controlled rolled rim can help create a smoother installed edge and reduce the risk of sharp burrs contacting fabric, cord or the user. The final rolled shape depends on the eyelet material, barrel length, setting die and material thickness.
Self-Piercing and Special-Shaped Eyelets
Self-piercing structures, oversized grommets, decorative flange designs and special-shaped openings can be evaluated according to the selected material and installation method. Custom logos, letters or surface patterns may also be possible when the flange size and forming depth provide sufficient space.
Custom Colors and Surface Treatments
Baocheng can coordinate eyelet colors with fabrics, leather, zippers, buckles, buttons and other metal accessories. Customers may provide a physical color sample, plated reference part, color card or target appearance image for evaluation.
| Finish Category | Typical Appearance Options | Project Considerations |
|---|---|---|
| Bright Metallic Finishes | Silver tone, nickel tone, gold tone, brass tone and copper tone | Suitable for clean, bright and decorative product designs |
| Dark Metallic Finishes | Black nickel, gunmetal, dark grey and black | Commonly coordinated with dark garments, bags, footwear and outdoor products |
| Antique Finishes | Antique brass, antique copper and antique silver | Provides a vintage or aged appearance; color variation limits should be confirmed |
| Matte or Brushed Finishes | Matte silver, satin, brushed or low-gloss appearance | Reduces excessive reflectivity and creates a more restrained visual effect |
| Colored Coatings | Black, white or project-specific colors where technically suitable | Coating adhesion and installation deformation should be tested before bulk production |
| Stainless Steel Treatment | Polishing, brushing, cleaning or passivation where applicable | Selected according to appearance and corrosion-resistance requirements |
Surface treatment availability depends on the base material, eyelet geometry, order quantity and required performance. Because the barrel is deformed during installation, Baocheng recommends evaluating the finished appearance after setting rather than approving color only on an uninstalled component.
Material Options for Custom Eyelets
| Material | Main Characteristics | Typical Selection Considerations |
|---|---|---|
| JSW20 Ultra-Low Magnetic Permeability Stainless Steel | Very low magnetic response after controlled forming, with stainless steel corrosion resistance and forming capability | Needle-detection-sensitive products, electronics-related applications and projects with defined magnetic permeability requirements |
| 304 or 316 Stainless Steel | Corrosion resistance, clean metallic appearance and good durability | Outdoor products, marine-related applications, workwear and humid environments |
| Brass | Good formability and compatibility with a wide range of decorative finishes | Apparel, footwear, leather goods, bags and premium decorative applications |
| Steel or Iron | Cost-effective and suitable for high-volume production | Projects requiring decorative plating or protective surface treatment |
| Other Materials | Special alloys and project-specific materials can be evaluated | Feasibility depends on formability, dimensions, order quantity and performance requirements |
Material selection should consider more than appearance. Corrosion environment, forming depth, flange strength, product weight, installation force, magnetic response and surface-treatment compatibility can all influence the final result.
JSW20 Patented Ultra-Low Magnetic Permeability Stainless Steel Eyelets
One of Baocheng's key material capabilities is JSW20, a patented ultra-low magnetic permeability stainless steel developed for components that require a very low magnetic response after manufacturing.
For conventional austenitic stainless steel, the raw material may appear non-magnetic before processing, but stamping, drawing, rolling and other cold-forming operations can change its microstructure and increase the magnetic response of the finished component. Therefore, a raw sheet that does not visibly attract a magnet does not automatically guarantee that the finished eyelet will meet a strict permeability or needle-detection requirement.
JSW20 is designed to maintain a magnetic permeability close to 1 after controlled cold forming. In relevant finished-component testing, Baocheng has achieved relative magnetic permeability values of approximately μr 1.0003. The value applicable to a specific order must be confirmed according to the eyelet geometry, forming process, surface treatment, assembly condition and agreed test method.
JSW20 eyelets can be considered for:
- Garments, footwear and accessories that must pass sensitive needle-detection procedures
- Products used near magnetic or electromagnetic-sensitive equipment
- Electronic accessories requiring low magnetic interference from small metal components
- Projects that specify a measurable relative magnetic permeability value
- Applications requiring both low magnetic response and stainless steel corrosion resistance
Customers with magnetic-control requirements should provide the target μr value, measuring instrument, test position, product condition and acceptance standard before sampling. Baocheng can then evaluate the requirement based on the finished eyelet rather than relying only on the raw material certificate.

| Apparel and Footwear | Hoodies, jackets, workwear, hats, corsets, sneakers and boots | Smooth edges, decorative appearance, consistent color and compatibility with fabric thickness |
| Bags, Leather Goods and Pet Products | Handbags, backpacks, belts, luggage, collars and harnesses | Hole reinforcement, abrasion resistance, appearance and pull-out performance |
| Curtains and Home Textiles | Curtains, shower curtains, furniture covers and soft furnishing products | Larger openings, clean rolling, color matching and support for repeated movement |
| Outdoor and Marine Products | Tents, awnings, tarpaulins, boat covers, canopies and protective covers | Corrosion resistance, washer support and resistance to repeated tension |
| Advertising and Display Products | Banners, flags, exhibition backdrops and hanging displays | Fast installation, reinforced holes and resistance to tearing around the opening |
| Packaging and Stationery | Calendars, folders, tags, gift bags, sample books and hanging packaging | Small dimensions, decorative appearance and stable high-volume production |
| Transport and Industrial Textiles | Truck tarpaulins, trailer curtains, cargo covers, filter bags and machine covers | Structural reinforcement, weather resistance and dimensional consistency |
Drawing-Based Development and Sampling Process
- Requirement Review: The customer provides a drawing, reference sample, installation material, application and expected order quantity.
- Material and Structure Evaluation: Baocheng reviews the eyelet dimensions, material, washer configuration, surface treatment and expected performance.
- Manufacturing Feasibility Review: Forming depth, barrel length, flange geometry, tolerances and installation conditions are checked before tooling.
- Tooling and Sampling: After the technical details are confirmed, tooling and samples can be prepared for dimensional, appearance and installation evaluation.
- Customer Approval: The customer verifies the sample on the actual fabric, leather, panel or product structure.
- Mass Production: Approved specifications, material and finish requirements are used as the basis for production and inspection.
Information Recommended for an Eyelet Quotation
- Technical drawing or physical reference sample
- Inner diameter, flange diameter, barrel diameter and barrel length
- Eyelet and washer material
- Total thickness and type of the installation material
- Required color and surface treatment

Quality Control for Appearance, Dimensions and Installation
An eyelet cannot be evaluated only by its appearance before installation. The barrel must roll or deform correctly, the flange should remain stable, the surface finish should not crack excessively and the installed eyelet should not create sharp edges that damage the surrounding material.
Depending on the project, Baocheng can establish inspection points for:
- Material grade and material thickness
- Inner diameter, flange diameter, barrel length and washer dimensions
- Burrs, cracks, deformation and edge condition
- Plating color, coating coverage and visible surface defects
- Eyelet and washer assembly compatibility
- Installation appearance on the customer’s specified material
- Pull-out or tension performance according to the agreed test method
- Magnetic permeability or needle-detection performance when specified
Material Documentation and Compliance Support

For relevant materials and projects, Baocheng can provide or coordinate supporting documentation such as the JSW20 patent certificate, OEKO-TEX-related documentation, RoHS and REACH reports, Intertek reports and nickel release test information.
The applicability of each certificate or report depends on the selected material, surface treatment, product configuration and target market. Customers should identify their compliance requirements before sampling so that the appropriate material and finishing route can be evaluated from the beginning.
