Product Description

35mm Reversible Pin Buckle with Curved Frame Design – Nickel Brush OEM

The S35-3566 is a 35mm reversible pin buckle engineered for modern, dual-sided leather belt programs. Its twistable, reversible mechanism enables quick switching between two belt faces without removing the buckle from the strap, helping brands and retailers offer “two looks in one” functionality while keeping the silhouette clean and contemporary.

From a product management standpoint, this buckle is positioned as a dependable core component for reversible belt collections: visually minimal, mechanically practical, and optimized for scalable OEM production. The brushed nickel finish supports broad styling compatibility across business, smart-casual, and uniform categories, while the curved frame profile provides a refined outline that reads premium without being ornate.

Product Features

Reversible Twistable Pin Mechanism

The buckle integrates a reversible, twistable pin structure designed to support fast face-switching for dual-sided belts. Users can rotate the buckle assembly to match the selected belt face, maintaining a consistent wearing experience across both sides. This mechanism is particularly suitable for reversible belt assortments where convenience and perceived value are key purchase drivers.

Clean Curved Frame Design

A gently curved frame softens the geometry of a classic rectangular buckle and delivers a balanced, streamlined look on the waist. The design intent is to complement a wide range of leather textures and colors while keeping the buckle visually stable in both formal and everyday use cases. The smooth contour also helps reduce visual bulk, which is beneficial for slimmer-profile belts and contemporary styling.

Zinc Alloy Nickel Brush Construction

Built with a zinc alloy base and finished in nickel brush, the S35-3566 targets reliable daily performance with a consistent, easy-to-merchandise surface appearance. The brushed finish helps minimize the visibility of minor handling marks in retail environments and supports cohesive matching with common metal accessories such as watch cases, bag hardware, and shoe buckles.

Dual-Sided Leather Belt Applications

Designed around 35mm belt width, this buckle is ideal for reversible leather straps used in:

• Men’s and unisex reversible belt lines
• Business wear and uniform belts requiring a clean metal presentation
• Gift-oriented “2-in-1” belt sets for department stores and e-commerce
• Private label programs seeking stable repeatable hardware supply

By enabling two colorways or textures on a single strap, the buckle supports assortment simplification (fewer SKUs) while improving the consumer’s perceived versatility.

Product Specifications

• Model: S35-3566
• Compatible Belt Width: 35mm
• Buckle Type: Reversible pin buckle (twistable mechanism)
• Frame Style: Curved frame design
• Material: Zinc alloy
• Finish: Nickel brush
• Application: Dual-sided / reversible leather belts

If your belt construction requires specific leather thickness clearance, pin geometry, or strap-end shaping, we recommend confirming strap specifications during sampling to ensure optimal fit and user feel.

Customization & OEM Service

The S35-3566 is suitable for OEM development where branding consistency, repeatable finish control, and production scalability are essential. Customization can be aligned to your market positioning—from mass retail to premium private label—while maintaining a stable core structure.

• Finish options: Alternative plating or surface treatments upon request (subject to feasibility and MOQ).
• Logo/branding: Customized logo placement (e.g., frame, backside, or dedicated branding area depending on design constraints).
• Color matching: Coordinated hardware finishing for full accessory sets.
• Packaging support: OEM packing specification, labeling, and barcode integration for retail or e-commerce.
• Sampling workflow: Prototype confirmation to validate mechanism feel, strap fit, and finish appearance before bulk production.

For efficient quoting, provide target order quantity, desired finish, logo requirements, belt thickness, and the intended market segment (e.g., uniform, business, fashion).

Frequently Asked Questions

Is this buckle designed specifically for reversible belts?

Yes. The twistable reversible mechanism is intended for dual-sided leather belt applications where the buckle orientation can be switched to match the selected belt face.

What belt width does it fit?

It is designed for 35mm belt straps. For best results, confirm the strap width tolerance and leather thickness during sampling.

What is the visual style of the finish?

The nickel brush surface provides a subdued metallic appearance with a clean, contemporary feel that is easy to style across multiple collections.

Can we add our brand logo?

Yes. OEM branding options are available. Final logo position and method depend on your design preference and structural considerations.

How do we ensure consistent fit with our leather straps?

Share your strap construction details (width, thickness, tip shape, and reversible structure). We recommend a sample approval process to confirm assembly compatibility and rotation performance.

Product Feature

35mm Reversible Pin Buckle with Curved Frame Design (S35-3566)

Designed for modern reversible belt programs, the S35-3566 is a 35mm reversible pin buckle that prioritizes repeatable function, visual restraint, and production-friendly integration. The silhouette is defined by a clean curved frame—an intentional geometry that softens the buckle’s presence on the waist while maintaining a structured, contemporary profile suitable for both business and smart-casual belts.

Material & Build Quality

This buckle is precision-cast from zinc alloy and completed with a nickel brush finish. The construction yields a substantial 54g weight, providing the mechanical robustness needed for frequent daily use in reversible belt operation. The brushed nickel surface presents a controlled, low-glare appearance that supports premium positioning while remaining practical for retail environments where fingerprints and minor wear must be managed.

The curved frame is not purely aesthetic: it contributes to improved ergonomics by reducing harsh edges against the belt body and the wearer’s waistline. As a result, the buckle maintains a refined look without compromising on structural stability.

Reversible Functionality

At the core of S35-3566 is a reversible twistable pin mechanism engineered to rotate freely. This allows quick, tool-free engagement from either side of a dual-sided leather belt. In production terms, it enables one buckle to reliably interface with belt holes from alternate directions—supporting true reversible belt designs without requiring the end user to manually reposition components.

For brands and manufacturers, this mechanism streamlines the reversible SKU strategy: one buckle design can serve multiple styling outcomes (e.g., black/brown belts) while preserving consistent fastening performance and minimizing user friction at the point of wear.

OEM / Wholesale Readiness

S35-3566 is built for scalable supply and brand customization. OEM options include custom logo engraving and multiple surface finish selections to align with house hardware language across product lines. MOQ starts at 300 pcs, with monthly capacity up to 100,000 pcs—supporting both program launches and ongoing replenishment with stable volume planning.

Recommended Applications

• Reversible leather belts (dual-sided strap programs)
• Men’s and unisex dress-casual belt collections
• Private label and branded hardware standardization initiatives
• Wholesale belt sets requiring consistent buckle performance across variants

The S35-3566 offers a balanced solution for reversible belt manufacturing: a durable zinc-alloy build, a controlled brushed nickel presentation, and a twistable pin mechanism that delivers practical, repeatable reversibility—packaged in a curved frame that enhances both comfort and perceived refinement.
