Pin Rivets

What Are Pin Rivets?

Pin rivets are metal fastening components made with two main parts: a cap section and a pin section. The pin part is usually made of aluminum, while the cap can vary depending on the product design, material requirement and production purpose.

This category belongs to the rivets group and is used for bags, leather goods, belts, footwear, textile accessories, fashion products and decorative metal applications. Pin rivets are different from standard single cap rivets and double cap rivets because the aluminum pin structure is an important part of the application system.

What Are Pin Rivets Used For?

Pin rivets are used when a product needs a visible decorative cap, a practical fastening structure or a metal detail on the surface. They are widely used in bag making, leather goods, belts, footwear, textile accessories and decorative zamak components.

The aluminum pin helps the rivet close into the cap during application. The correct pin length should be selected according to the total thickness of the material. A short pin may not close properly on thicker materials, while a pin that is too long may bend, crush or create an uneven surface during installation.

Aluminum Pin Structure in Pin Rivets

The pin section used in pin rivets is generally made of aluminum. These aluminum pins can be supplied in short, medium and long lengths according to the material thickness and application type.

Depending on the manufacturer or workshop terminology, these pins may be called K1, K2, K3, K4 or D1, D2, D3, D4. In many applications, D2 and D3 pin structures are commonly preferred. The correct code should be evaluated according to cap form, material thickness, application surface and setting tool compatibility.

Brass Cap and Custom Logo Pin Rivet Production

Pin rivets can be produced with brass caps when the project requires a stronger plated appearance, a premium cap surface or a custom branded detail. Brass cap production can be suitable for bag, footwear, belt and leather accessory brands that want a more distinctive metal finish.

Custom logo, branded cap, special pattern or custom cap form production can be evaluated according to cap size, pin length, material, finish color, quantity and design detail. For custom logo or brass cap pin rivet production, customers can contact us with their required size, design and application information.

Relation with Decorative Zamak Rivets

Pin rivets are also used in decorative zamak rivet applications. A decorative zamak cap or ornament can be applied with an aluminum pin structure, creating a visible decorative metal detail on bags, shoes, belts, leather accessories and fashion products.

Decorative cap forms can be flat, raised, shaped, patterned, logo-based or custom-designed. For related options, review decorative zamak rivets. Cap material, pin length and setting tool compatibility should be checked before production or application.

Where Are Pin Rivets Used?

• Bag and leather accessory production
• Belts, wallets, card holders and small leather goods
• Footwear, boots and sandal decorative parts
• Textile garments, vests, jackets and fashion accessories
• Decorative zamak cap rivet applications
• Custom logo rivets and branded metal accessories
• Costumes, stagewear and design-focused products

Difference Between Pin Rivets and Other Rivet Types

Pin rivets are applied with an aluminum pin structure and a separate cap part. This makes them different from many standard rivet types. Single cap rivets create a finished cap on one side of the product, while double cap rivets create a finished cap appearance on both sides.

If the material is thick, layered or requires a deeper fastening point, you can also compare long post rivets. Selection should be based on product use, total material thickness, cap material, pin length and installation method.

Setting Die and Application Tool Compatibility

Pin rivets should be installed with a setting die compatible with the cap form, pin length and product structure. Related application tools can be reviewed under rivet assembly tools.

Compatible setting dies and application tools can be used with hand-setting tools, hand presses, impact presses, electric machines and pneumatic machines. Final compatibility should be checked according to the product system, size, connection structure and die standard.
