In everyday textiles, footwear, and gear you’ll often encounter tiny rings that perform big jobs. An eyelet is one of the most versatile fasteners in crafts, sewing, upholstery and outdoor equipment. What is an Eyelet? Put simply, it is a reinforced ring that sits in a hole to protect the surrounding material and to guide or constrain a cord, lace or rope. From a practical point of view, eyelets stop fabric from fraying, distribute tension more evenly and provide a neat, durable point of passage for strings and cords. For designers, makers, and homeowners alike, understanding what is an eyelet helps you select the right type, install it correctly and extend the life of your projects.
What is an Eyelet? A Clear Definition
What is an Eyelet? At its core, an eyelet is a small hole reinforced by a ring or collar. This reinforcement can be metal, plastic or composite, and it serves two main purposes: to prevent tearing around the hole and to provide a smooth channel for a lace, drawstring or wire. The term covers a broad family of fasteners, from simple metal rings hammered into fabric to more sophisticated self-piercing variants used in industrial settings.
Key characteristics of an eyelet
- Reinforced edge: The outer ring or flange protects the material surrounding the hole from wear and tear.
- Central bore: The hollow centre allows the passage of a cord, rope or wire without snagging.
- Material versatility: Eyelets come in brass, stainless steel, aluminium, polypropylene and other materials to suit different environments.
- Finish and colour options: From bright brass to matte black, finishes can be chosen to match aesthetics and corrosion resistance.
- Installation method: Some eyelets are set by hand with a setter tool; others are installed with rivets, grommets or punching machines.
Eyelet, Grommet, and Their Relationship
An important distinction when exploring what is an eyelet is its relationship to a grommet. A grommet is a type of eyelet often used for similar purposes but typically composed of two pieces: a metal ring and a washer that press over the material from both sides. The assembly creates a durable reinforced hole, ideal for high-stress applications such as sails, tents or equipment with repeated tension. In common usage, people may interchange the terms loosely, yet in technical settings a grommet usually refers to the two-part assembly, whereas an eyelet may be a single ring or a simple metal rim that is set into fabric or leather. Understanding this nuance helps you pick the correct hardware for what you intend to do.
Materials and Finishes: What is an Eyelet Made Of?
Metal eyelets
Metal eyelets are popular for their strength and longevity. Brass eyelets offer corrosion resistance and a warm, antique look, while stainless steel eyelets provide maximum durability in challenging conditions. Aluminium eyelets are lighter and resistant to rust, making them suitable for camping gear and lightweight fabrics. When you ask, “What is an Eyelet made of?” metal options are often the default answer for projects that require resilience and ease of installation with traditional tools.
Plastic and composite eyelets
Plastic eyelets are useful for low-stress applications such as decorative garments, children’s clothing, or craft projects where weight, cost, and chemical resistance are considerations. Some composites blend plastic with reinforced fibres to increase rigidity while keeping the piece affordable. In areas with extreme heat or UV exposure, specialist plastics can offer superior longevity compared with plain metal rings that may tarnish or corrode.
Coatings and finishes
Finishes extend life and create a specific look. Bright nickel, antique bronze, black oxide and coloured coatings are all common. Finishes can enhance corrosion resistance, reduce glare, or simply complement the design language of a garment or bag. When choosing what is an eyelet for outdoor use, consider finishes that resist moisture and salt, particularly in coastal environments or when used in marine contexts.
Common Types of Eyelets
Standard metal eyelets
The workhorse of many wardrobes and projects, standard metal eyelets come in various diameters and flange sizes. They’re versatile for clothing, leather goods, and light upholstery. Typical diameters range from around 5 mm to 12 mm outer diameter, with inner bore sizes large enough for typical drawstrings or cords.
Brass, steel and aluminium variants
Brass eyelets provide elegance and natural corrosion resistance, often used in vintage or premium pieces. Steel eyelets are the most robust option and are common in workwear and heavy gear. Aluminium variants strike a balance between lightness and strength, ideal for travel bags or tents where weight matters.
Self-piercing and reinforced eyelets
Self-piercing eyelets cut their own hole as they are installed, saving a separate punching step. They’re convenient for DIY projects and quick repairs. Reinforced eyelets feature a thicker flange and stronger shank, improving resistance to tearing when subjected to heavy loads or repeated use.
Decorative and specialised eyelets
Decorative eyelets add visual appeal while maintaining functionality. Specialised eyelets may be used for cord guides on jewellery, dreamcatchers, or crafts where aesthetics are as important as function. Some eyelets are designed to sit flush against leather or fabric for a sleek appearance, while others protrude for a more rugged look.
Sizes, Measurements and Standards: How to Read Eyelet Specifications
Outer diameter and inner bore
Eyelets vary by outer diameter (the flange width) and inner bore (the hole through which the cord passes). When planning a project, measure the cord you intend to thread and select an eyelet with an inner bore comfortably larger than the cord but not so large that it compromises the fabric’s strength.
Hole size, gauge and shank length
The hole size must align with the fabric’s thickness and the eyelet’s shank length. A longer shank provides more grip, which is helpful for thicker materials but may require a deeper setting tool. Gauge or thickness of the material being reinforced is key; too small and the eyelet risks tearing the fabric, too large and it may not hold securely.
Standards and tolerances
Manufacturers publish tolerances to help you forecast how a given eyelet will perform in practice. When dealing with high-speed production or critical load-bearing applications, consult the supplier’s data sheet for recommended installation pressures, maximum loads and compatibility with drilling or punching equipment.
Where You Might Encounter Eyelets
Eyelets appear across many domains. In clothing, they brace laces on hoodies, shoes or corsetry. In bags and purses, eyelets guide straps or tighten cords. Outdoor gear uses eyelets in tents, tarps and rainwear to shed stress and avoid fabric damage. Leathercraft, upholstery and drapery also rely on reinforced holes to maintain structure and appearance. Even in household projects such as curtains or laundry bags, an eyelet can provide a neat finish and extend product life.
How to Choose the Right Eyelet for Your Project
Purpose and load
Ask what is the eyelet’s purpose in your design. If the eyelet must withstand repeated tension from a drawcord, select a robust metal option with a thick flange and corrosion-resistant finish. For decorative purposes or light use, a plastic or decorative eyelet may be perfectly adequate.
Material compatibility
Consider the interacting materials. Leather requires firm resistance to tearing; fabric may be more forgiving but benefit from larger flange contact to distribute stress. In damp environments, choose corrosion-resistant metals or coated finishes to prevent rust and staining.
Installation method
Will you hand-set the eyelets with a setter and mallet, or do you have access to a punching and setting machine? Self-piercing eyelets enable quicker installation, while press-fit options can provide a very secure hold for heavy uses. Always match the eyelet type to the equipment you have available to install it properly.
Installing Eyelets: A Step-by-Step Guide
Installing an eyelet correctly is essential to its performance. Here is a practical, straightforward method that works for most standard projects. If you’re working with delicate fabrics, test on a scrap piece first to avoid damage.
Tools you might need
- Appropriate eyelets (correct size for your project)
- Eyelet setter or setting pliers
- Hammer or mallet
- Hole punch or awl to create a clean hole
- Cutting mat or scrap board to protect surfaces
- Ruler or calipers for precise measurement
Step-by-step process
- Mark the position of the hole on the material, ensuring symmetry and spacing if multiple eyelets are used.
- Create a clean, properly sized hole. A punch or sharp awl can help prevent fraying, especially on fabric or thin leather.
- Insert the eyelet into the hole from the correct side. The flange should sit flush against the surface on the outside of the material.
- Place the setter over the eyelet and gently strike with a hammer or use the setting tool as directed by the manufacturer. Apply steady, even pressure to crimp the flange and secure the ring in place.
- Inspect for a neat finish. The outer flange should be flat against the fabric; there should be no gaps or burrs that could abrade the cord or irritate the user.
Alternative installation methods
Some projects may use rivet-like eyelets or thermal setting processes. For garments and soft goods, a simple punch and setter method is usually sufficient. Heavy-duty eyelets used for industrial or outdoor gear may require a more robust press or machine setting to achieve a secure finish.
Care and Maintenance for Eyelets
To get the most from what is an eyelet, keep them clean and check regularly for signs of wear. Dirt and moisture can accelerate corrosion in metal eyelets, particularly in coastal climates or where salt is used on roads. A quick wipe with a dry cloth after exposure to moisture can help extend life. If an eyelet becomes loose, replace it promptly to prevent further damage to the surrounding fabric.
Cleaning and rust prevention
For metal eyelets, avoid abrasive cleaners that could scratch the finish. A soft cloth and mild soap are usually enough. If you notice dullness or rust spots, treat them with a rust inhibitor suitable for the metal type and allow to dry completely before re-use. For outdoor gear, periodic inspection and maintenance will pay dividends in longevity.
Replacement and repair
Damaged eyelets should be replaced rather than repaired. Removing a worn eyelet can widen the hole; in such cases, use a larger eyelet or a reinforced patch to restore strength. When you replace eyelets, ensure the new size matches the original gauge and hole diameter to maintain uniformity and function.
