4.5 mm / 0.18 in sheet steel eyelet: specifications, selection and installation guide

4.5 mm / 0.18 in Sheet Steel Eyelet – 250 Pieces K0003 is designed for bags, footwear, labels, textiles and craft projects where a clean reinforced opening and repeatable installation are required. The 250-piece pack supports workshop use, samples and regular production. With the correct punching die, matching setting die and controlled press pressure, the eyelet can be installed more consistently across repeated jobs.

How to choose the correct size

Do not choose an eyelet only by its visible outer diameter. Consider the inner opening, material thickness, the cord or component passing through the eyelet and compatibility with the installation tooling. An oversized preparation hole can create movement after setting, while an undersized hole can place unnecessary stress on the surrounding material.

Pre-installation checklist

• Compare the inner and outer diameters with the project requirements.
• Check the material thickness and number of layers.
• Confirm that the punching and setting dies belong to the same size family.
• Run a trial on scrap material before full production.
• Start with controlled press pressure and adjust gradually.
• Check finish and color before using a full production batch.
• Verify that the finished eyelet does not rotate or sit unevenly.
• Recheck pressure when material thickness changes.
• Remove burrs or irregular cut edges before setting.
• For visual consistency, use the same production batch where possible.

Matching setting die

Use the matching No. 2 eyelet setting die. The correct die helps form the eyelet in a controlled way and keeps the finished assembly centered. Using a mismatched die may distort the rim, scratch the finish or create an uneven set.

Matching punching die

Before installation, prepare a clean and correctly sized opening with the matching eyelet punching die. Hole quality directly affects installation quality, especially on tarpaulins, leather, multilayer textiles and technical fabrics.

Press and production equipment

For regular or higher-volume production, combine the matching setting die with the M0099 hand press. Controlled press pressure improves repeatability and makes it easier for operators to use the same motion from piece to piece.

Recommended installation sequence

1. Mark the installation point.
2. Check material thickness.
3. Punch the opening with the matching die.
4. Insert the eyelet from the face side.
5. Position the backing component correctly.
6. Install the matching setting die in the press.
7. Center the components.
8. Apply controlled pressure.
9. Inspect the rolled edge and surrounding surface.
10. Before full production, test the sample for rotation and pull resistance.

Applications and project selection

For bags, footwear, labels, textiles and craft projects, the eyelet is not only decorative; it also finishes the edge of the opening and improves the professional appearance of the application. Measure the real clearance needed for cord, lacing or the passing component before ordering.

Benefits for workshop and production use

The 250-piece pack supports stock planning for frequently used sizes. When the eyelet, punching die, setting die and press are kept in the same size family, setup errors are reduced and operators can achieve more consistent results with less trial and error.
