Modular Color-Ring Knob Screws for Multi-Brand OEM and In-House Lines

This case highlights how UJEN’s modular color-ring knob screws helped a long-established Taiwanese manufacturer unify its mechanical platform while differentiating visual identity across multiple OEM clients and its own brand. With a single knob screw base and interchangeable color rings and center caps, the company can precisely reflect different brand colors and styles without multiplying core part numbers.

Client Background｜Over 30 Years in Machinery Accessories and Woodworking Equipment

Established in 1989, the client has grown from an OEM supplier of machinery accessories into a trusted manufacturer of woodworking saw equipment and compact woodworking machines. Its products have earned CSA safety certification and are sold into demanding markets such as the United States and Canada. With ISO9001 quality management and CE-compliant equipment serving Europe, Japan, and Korea, the company now supports both its own branded products and numerous global customers as an OEM/ODM partner.

Challenge｜One Component Platform, Many Brand Identities

As an OEM/ODM manufacturer with its own brand, the client needed a way to:

• Support different international brand color schemes for multiple OEM customers.
• Maintain a distinct, recognisable look for its own branded machines.
• Avoid excessive part proliferation and complex inventory for knob screws.

The key question was how to use one mechanical knob screw platform to express multiple brand identities through both form and color, without sacrificing production efficiency.

UJEN Solution｜Modular Knob Screws with Swappable Center Caps and Color Rings

When evaluating suppliers, the client discovered UJEN’s modular, style-and-color customizable knob screw series. The concept is simple but powerful:

• The knob screw body is a standardized, high-quality base with a consistent thread and mechanical performance.
• The top section is modular, allowing different center cap designs and a circular color ring to be installed on the same base.
• The center cap is available in at least four distinct shapes, enabling different visual styles while preserving the same mechanical footprint.
• Both the center cap and the circular color ring can be produced in at least seven standard colors, and further matched to specific PANTONE codes when brand guidelines require it.

By combining one base, multiple center-cap shapes, and multiple ring colors, the system creates hundreds of possible combinations, supporting diverse brand stories without redesigning the core fastening component.

Multi-Brand Application｜Same Knob Screw, Different Color Rings for Each Brand

The manufacturer quickly realized the strategic value of this approach:

• For OEM clients, the same knob screw design can be used with different circular color rings and center caps matched to each brand’s corporate color, giving every customer their own distinct visual expression.
• For its own brand, the company can select a unique combination of cap style and color ring, clearly separating its identity from OEM projects even though the internal mechanics are identical.
• Inventory is simplified because the mechanical base remains the same; only the decorative and color parts vary by project.

Results｜Color and Form as Brand Amplifiers, Without Operational Complexity

By adopting UJEN’s modular color-ring knob screws, the client achieved:

• Higher OEM customer satisfaction through precise brand-color alignment on visible touch points.
• A stronger, more coherent visual identity for its own branded machines.
• Simplified production and inventory management thanks to a shared knob screw base.
• Improved perceived quality, as the knobs now support both functional ergonomics and refined aesthetic details.

UJEN Insight｜Small Components, Big Brand Impact

UJEN believes that even small fastening components can play a strategic role in branding and product differentiation. With modular design, interchangeable color rings, and customizable center-cap shapes, UJEN’s knob screw series transforms a standard mechanical part into a flexible branding tool.

If your company manages multiple OEM brands, regional variants, or its own in-house line, UJEN’s color-and-form configurable hardware can help you maintain a unified mechanical platform while expressing distinct brand personalities. One knob body, many visual identities—that is how UJEN turns precision fastening into brand value.
