2.5 mm / 0.10 in Steel Pin, 25x45, 5,000 Pieces MRTP002545

What Is a 2.5 mm / 0.10 in Steel Pin Used For?

This 2.5 mm / 0.10 in steel pin is a compact fastening component supplied in a 5,000-piece pack. It can be used in small leather goods, wallets, card holders, textile accessories, decorative metal details and other products where a controlled small fastening point is required.

The pin is not a complete installation system by itself. For accurate and repeatable application, use a compatible Pin Setting Die matched to the pin group and the material being assembled.

Technical Size Information

The product specifications list a 4.5 mm / 0.18 in outer diameter, 2.5 mm / 0.10 in inner diameter and 3.2 mm / 0.13 in height. The 25x45 label identifies the product size group. Do not treat it as a separate length-by-width measurement unless it is confirmed by an engineering drawing.

Suitable Applications

• Small leather goods, wallets and card holders
• Leather and synthetic-leather accessory details
• Fine textile accessory assembly
• Decorative metal component attachment
• Craft, hobby and small-scale repair projects
• Compact bag and accessory production
• Small-component assembly in workshop production

Matching Pin Setting Die

Use this pin with the matching 2.5 mm / 0.10 in Pin Setting Die KLP002545. The setting die is intended for the 2.5 mm pin diameter and the 25x45 pin group.

A Pin Setting Die installs and secures the pin. It does not cut the material. When a pre-hole is needed, choose the hole size according to the actual pin form, material thickness and sample application result.

When Is a Hole Cutter Needed?

A pre-hole is not required for every application. On thin or flexible materials, the pin may be applied without pre-cutting when the pin system and pressure are suitable. Thick leather, layered textiles, coated fabrics or rigid materials may require a controlled pre-hole.

Where a 2.5 mm / 0.10 in opening is genuinely needed, the 2.5 mm / 0.10 in Hole Cutter may be considered after a sample test. A Hole Cutter prepares the opening only; it does not install the pin.

Available Finishes

• Nickel
• Black Nickel
• Antique Brass
• Black Oxide

Select the finish according to nearby buckles, rings, chains, zipper pullers or other metal components. Small visual differences can occur because of plating variation, display settings and lighting conditions.

Application Order

1. Check the material thickness and pin compatibility.
2. Prepare a pre-hole only when the application requires it.
3. Position the pin at the intended fastening point.
4. Install the pin with the matching Pin Setting Die.
5. Check that the pin is seated evenly without damaging the material.
