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

What Is a 33.5 Double Cap Rivet Setting Die Used For?

This 33.5 Double Cap Rivet Setting Die is used to install compatible double cap rivets with controlled pressure. Double cap rivets create a finished cap appearance on both sides of the material assembly, making them suitable for visible fastening points in leather goods, bags, belts, wallets and textile accessories.

This is a Rivet Setting Die. It does not manufacture rivets and does not punch holes in the material. Hole preparation, rivet selection and final setting are separate steps.

9 mm Setting Size and 9.5 mm Cap Diameter

The setting tool is listed with a nominal 9 mm / 0.35 in size, while the related compatible rivet has a visible cap diameter of 9.5 mm / 0.37 in.

These values describe different parts of the system. The setting-tool size refers to the die’s working surface group, while the 9.5 mm dimension refers to the rivet cap diameter. Use this die with the related compatible 33.5 double cap rivet rather than assuming that any rivet with a similar nominal size will fit.

Compatible Double Cap Rivet

This die is listed with the compatible 33.5 Double Cap Rivet with a 9.5 mm / 0.37 in cap diameter. The related rivet has an approximately 7.5 mm / 0.29 in post length and is intended for applications where both sides need a clean visible finish.

Post length must suit the total thickness of the actual material stack. Consider all layers together: leather, synthetic leather, webbing, lining, textile, reinforcement material or bonded layers.

Not for Nail Rivets or Single Cap Rivets

This die is for double cap rivets. It should not be used for nail rivets or single cap rivets unless the actual rivet geometry has been specifically confirmed by the manufacturer.

Nail rivets use a different nail-and-cap construction. Single cap rivets also use a different reverse-side structure. Similar cap sizes do not make these systems interchangeable.

Does This Tool Punch a Hole?

No. This is a Rivet Setting Die, not a Punching Die. The rivet post requires a separately prepared hole that matches the actual rivet construction and material structure.

The related rivet page lists a 2.5 mm / 0.10 in hole cutter as a compatible accessory. Treat this as a selection guide, then confirm the result with the real rivet and real material before production.

Suitable Applications

• Leathercraft, wallets, card holders and small leather goods
• Bag handles, bag straps and reinforcement points
• Belts, webbing and strap assemblies
• Canvas, textile and organiser products
• Visible fastening points in apparel and accessories
• Repairs, sample making and small-batch workshop work

Hand Press and Hammer Use

This setting die can be used with a compatible manual hand press. It can also be used in hand-hammer applications when the die and rivet are positioned securely on a stable, flat surface.

For repeatable work, use a compatible Manual Hand Press. Hand-hammer use requires more care because off-centre impact can affect cap alignment and surface finish.

Press Connection

The product options list M6 and 1/4 in connection choices. These are not interchangeable thread standards. Confirm the real thread diameter, pitch and die-holder structure of the press before selecting the option.

A converter may be required when the die connection and machine connection do not match. Similar outside diameters do not confirm safe mechanical compatibility.

Correct Application Sequence

1. Select the compatible 33.5 double cap rivet.
2. Check cap geometry, post length and total material thickness.
3. Prepare the correct hole for the real rivet post.
4. Position the lower cap and post through the material.
5. Place the upper cap onto the post.
6. Align the rivet in the lower and upper die surfaces.
7. Apply controlled pressure with a hand press or secure hand-hammer method.
8. Inspect cap alignment, closure security, movement and surface condition.

Frequently Asked Questions

What rivet system is this die for?

It is for compatible 33.5 double cap rivets with a 9.5 mm / 0.37 in cap diameter.

Why does the die say 9 mm while the compatible rivet cap is 9.5 mm?

The 9 mm value identifies the nominal setting-tool size, while 9.5 mm identifies the visible cap diameter of the related rivet. Use the verified matching system rather than selecting by one measurement alone.

Can this die be used for nail rivets?

No. Nail rivets use a different construction and require their own compatible setting die.

Does this die punch leather, textile or webbing?

No. It is a Rivet Setting Die. Punching must be completed separately.

Can it be used with a manual hand press?

Yes, when the die holder and press connection are physically compatible.

Can it be used with a hammer?

Yes. Keep the die, rivet and workpiece stable on a flat surface and use controlled impact.

What should be tested before production?

Test the real rivet, post length, hole preparation, material stack and setting pressure together.
