No. 31 Self-Piercing Eyelet Die Set - 17 mm / 11/16 in KLP0031D

The No. 31 self-piercing eyelet die set for 17 mm / approx. 11/16 in eyelets is designed for users who need a practical, clean and professional solution for installing large eyelets. It is suitable for No. 31 eyelet applications and helps achieve a neat installation result on compatible materials such as tarpaulin, awning fabric, bags, banners, covers, decorative textile panels and similar technical textile projects.

This product includes 1 upper die and 1 lower die. Thanks to its self-piercing structure, it helps reduce the need for a separate pre-punching step on suitable materials. With the correct press, matching eyelet and proper alignment, the cutting and setting process can be completed in a more practical and controlled way.

Package Content

Note: This product does not include eyelets, washers or a press machine. The package includes only 1 set of mounting dies. Eyelets, washers and hand press machines should be purchased separately. Before ordering, please check your press thread size and connection type for compatibility.

Application Areas

The No. 31 - 17 mm / approx. 11/16 in eyelet die set can be used for tarpaulins, awnings, banners, bags, covers, curtains, decorative panels, leather-like materials and technical textile applications. It is especially useful when a wider eyelet opening and a stronger fastening point are required. For the best result, the eyelet size, material thickness, washer selection and press pressure should be compatible with each other.

How to Use

1. Prepare the compatible No. 31 eyelet with a 17 mm / approx. 11/16 in inner diameter and the suitable washer if needed.
2. Install the upper and lower die correctly on your press machine.
3. Place the material in the correct position between the dies.
4. Press down in a controlled way to allow the eyelet to pierce and set into the material.
5. Before regular production, test the application on the same material to adjust pressure and alignment.

Why Choose a Self-Piercing Eyelet Die?

In standard eyelet applications, the material usually needs to be punched first and the eyelet is then installed in a separate step. A self-piercing die helps simplify this process on suitable materials by supporting cutting and setting during the same press action. This can save time, improve workflow and help achieve a more consistent installation in repetitive applications.

Important Usage Notes

• Use this die only with compatible No. 31 eyelets.
• Always test first on very thick, hard, elastic or multi-layer materials.
• Check your press connection size before ordering.
• If the die alignment is incorrect, the eyelet may not close properly.
• For a professional result, use the correct eyelet, suitable washer and balanced press pressure.
