Multi-color Plastic Clamping Knob Screw (Nut) Overview

Multi-color plastic clamping knob screws integrate visual identification into hand-operated fastening. By combining a center color disc and an outer color ring on the knob top, users can distinguish functions, operating states, or product variations at a glance while maintaining reliable clamping performance.

Dual-Color Knob Design

The dual-color design consists of two independently selectable color components and multiple surface styles, creating a flexible system for both functional coding and visual differentiation.

• Center color disc combined with an outer color ring
• Seven standard colors available for each component
• Four surface styles: concave, flat, convex, and dotted

196 Standard Combinations

By combining color and surface variations, the system provides a wide range of predefined configurations without requiring custom tooling for each design.

• 7 disc colors × 7 ring colors × 4 surface styles
• Total of 196 standard visual combinations
• Supports clear differentiation across product lines or functions

Function-Based Color Coding

• Visual identification of motion direction or adjustment points
• Color-based distinction between safety levels or operating states
• Improved usability in multi-function or modular equipment

Design Flexibility & Brand Alignment

• Color selection aligned with corporate identity or product themes
• Consistent appearance across different equipment models
• Enhanced visual quality for consumer-facing or premium products

Typical Applications

• Fitness equipment with function-differentiated adjustment knobs
• Medical beds, carts, and modular systems using color-coded fasteners
• Precision instruments requiring visual and tactile control points
• Consumer electronics and furniture with visible fastening elements
• Operator panels requiring high visibility and intuitive interaction
