33.5 Double Cap Rivet Setting Die for 9.5 mm / 0.37 in Cap Rivets KLP00335CFT

33.5 Double Cap Rivet Setting Die

This 33.5 Double Cap Rivet Setting Die supports clean and balanced installation of compatible double cap rivets. Double cap rivets provide a visible cap finish on both sides, making them useful for leather goods, bags, belts, wallets, textile accessories and other visible fastening areas.

This product is a setting tool. It does not create the rivet hole and does not replace the need to select the correct rivet post length for the actual material stack.

9 mm Setting Tool and 9.5 mm Cap Rivet

The 9 mm / 0.35 in figure identifies the nominal setting-tool size. The 9.5 mm / 0.37 in figure identifies the visible cap diameter of the compatible double cap rivet.

These are not conflicting measurements. They describe separate parts of the same setting system. Use the matching double cap rivet and this setting die together rather than assuming any rivet with a similar diameter will fit.

Double Cap Rivet Use

Double cap rivets are selected where both sides of the fastening point remain visible. They help create a cleaner finished appearance in bag handles, belts, leather straps, wallets, card holders, garment details and decorative accessory connections.

Not for Nail Rivets or Single Cap Rivets

This tool is not intended for nail rivets or single cap rivets. Those rivet types use different cap structures and different setting surfaces.

Even when the visible cap size appears similar, rivet geometry and closing structures can differ. Use the die matched to the real rivet system.

Hole Preparation

This is not a Punching Die. Prepare the rivet hole separately according to the actual rivet post and material structure.

Check the real leather, synthetic leather, webbing, canvas or textile stack before production. Hole size, post length and material thickness affect the final fastening strength.

Hand Press and Hand Hammer Use

The die can be used with a physically compatible manual hand press. It can also be used with a hammer when the die and rivet are held securely on a flat, stable surface.

For repeated production, a hand press provides more consistent control. For hammer use, keep the die centred and apply controlled impact to avoid uneven closing.

Installation Checklist

1. Select the compatible 33.5 double cap rivet.
2. Check cap shape, post length and total material thickness.
3. Prepare the correct rivet hole.
4. Position the lower cap and post through the material.
5. Place the upper cap onto the post.
6. Align the rivet in the setting surfaces.
7. Apply controlled pressure or hammer impact.
