Extra-Long Domed Eyelet for Thick and Layered Materials
This extra-long domed sheet metal eyelet is used to create a neat metal finish around small lace, cord and fastening openings on footwear, bags, leather goods, thick fabrics, multi-layer textiles, protective cases and suitable accessory products.
The 5.3 mm / 0.209 in inner opening can accommodate compatible thin cords, laces and fastening components. Its 9.7 mm / 0.382 in domed outer surface covers the edge of the prepared opening, while the 7.5 mm / 0.295 in barrel is formed over the selected washer during installation.
The extra-long barrel can be considered when the barrel of a standard eyelet is not long enough to pass through the complete material stack. Final suitability must be tested using the actual material, washer, setting die and press adjustment.
Material Information
This product is made from sheet metal. It must not be described as brass or stainless steel. The extra-long brass version is a separate product under code MT0003EUP.
When Should This Eyelet Be Selected?
- When an eyelet in the 5–5.5 mm / 0.197–0.217 in inner-diameter class is required
- When a standard barrel is too short for the material layers
- For thick fabrics and multi-layer textile applications
- When additional barrel length is required for leather or faux leather
- When a domed and more visible front profile is preferred
- When a plastic or metal washer option is required
- For footwear, bags, garments, tags and accessory production

How Does It Differ from the Standard Version?
The standard K0008 sheet metal eyelet measures 5.3 mm / 0.209 in inside diameter, 9.2 mm / 0.362 in outside diameter and 6 mm / 0.236 in in barrel height.
This extra-long model retains the 5.3 mm / 0.209 in inner diameter but has a 9.7 mm / 0.382 in outer diameter and a 7.5 mm / 0.295 in barrel height.
The barrel is approximately 1.5 mm / 0.059 in longer than the standard version. This additional length may be useful when working with thicker or more heavily layered materials.
A Longer Barrel Is Not Automatically Better
A barrel that is too long for a thin material may fold excessively, lean to one side or close unevenly over the washer. Select the standard or extra-long version according to the compressed thickness of the complete material stack.
Plastic Washer or Metal Washer?
Plastic washer
A plastic washer can be considered when a lighter and softer rear support is preferred for suitable garments, textiles, tags and accessory applications.
Metal washer
A metal washer may be selected when a conventional all-metal connection and a metal rear finish are preferred for footwear, bags, leather accessories and similar products.
Plastic and metal washers are separate product options. Confirm the selected finish, washer type and quantity before completing the order.
Finish Options
- Nickel
- Black Nickel
- Gold
- Antique Brass
- Black Oxide
The selected finish changes the appearance of the eyelet. It does not change the sheet-metal base material into brass or stainless steel.
This Product Is Not Stainless Steel
For continuous moisture, sweat, water, frequent washing or demanding outdoor exposure, verify the suitability of the selected finish. Consider a brass or stainless-steel alternative when higher corrosion resistance is required.
Typical Applications
- Footwear lace and cord openings
- Bags, wallets and carrying cases
- Thick fabrics and multi-layer textiles
- Leather and faux-leather accessories
- Jackets, coats and workwear details
- Tags, sample cards and thick cardboard
- Protective and camping textile products
- Craft and decorative accessory projects
Compatible Setting Die and Hole Preparation
A setting die suitable for eyelets in the approximately 5–5.6 mm / 0.197–0.220 in inner-diameter class may be used to form the barrel over the selected washer.
A 5 mm / 0.197 in punching die or Padova punching tool can be considered for preparing the installation opening. Material thickness, stretch, fibre structure and number of layers can affect the required opening.
The diameter class may be suitable for the standard setting die, but the 7.5 mm / 0.295 in extra-long barrel may require a compatible die profile and a different press adjustment. Test the complete system before production.
Installation Steps
- Mark the required eyelet position.
- Check the total compressed thickness of the material layers.
- Prepare a controlled opening with a compatible 5 mm / 0.197 in punching tool.
- Insert the eyelet through the front of the material.
- Position the selected plastic or metal washer on the rear side.
- Centre the eyelet and washer in the setting die.
- Begin with low press pressure and apply the force gradually.
- Check that the extra-long barrel opens evenly over the washer.
- Increase the press adjustment only in small steps when necessary.
- Begin production only after completing a successful sample installation.
Selection and Installation Warnings
- Do not select the product using only a traditional size number.
- Check the inner diameter, outer diameter and barrel height together.
- Do not assume the extra-long barrel is suitable for thin materials.
- Do not prepare an opening larger than required.
- Keep the eyelet and washer centred in the setting die.
- Do not position the setting die at an angle.
- Do not apply excessive press force in one step.
- Do not describe the product as brass or stainless steel.
A Sample Installation Is Essential
Material thickness, number of layers, prepared opening, washer type, setting-die profile and press adjustment directly affect how the extra-long barrel closes. Test the eyelet, washer, material and setting die together before final production.
