Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Vibration Reduction & Secure Mounting: Designed to absorb shocks and vibrations in mechanical systems while securely fastening components like motorcycle windshields, motors, or pumps via threaded inserts.
  • Multi-Material Compatibility: Available in NBR, FKM, silicone, EPDM, rubber, and plastic to suit temperature, chemical, and wear-resistance requirements.

Key features

  • 1. Advanced Material Technology for Harsh Environments

    • With NBR and FKM rubber compounds, resist extreme temperatures, oils, and chemicals better than standard rubber bushings*. This ensures durability in automotive and industrial applications where exposure to harsh elements is common.

  • 2. Secure Threaded Design for Easy Installation

    • Threaded inserts allow for tool-free, reliable fastening to metal components, unlike traditional press-fit designs*. This simplifies assembly and disassembly in tight mechanical spaces.

  • 3. Vibration and Friction Reduction for System Stability

    • Engineered with high-performance rubber and plastic composites, absorb up to 30% more vibration compared to non-rubber solutions*, reducing wear on connected machinery and enhancing longevity.

  • 4. Tailored for Motorcycle and Automotive Applications

    • Designed specifically for motorcycle windscreen mounting and mechanical systems, providing a stable, noise-dampening solution for dynamic environments like vehicle suspension systems.

  • 5. Customizable Molding for Precision Fitments

    • With customizable molding services, adapt to specific thread sizes, shapes, and material requirements—unlike generic off-the-shelf alternatives*. Ideal for specialized industrial or automotive projects.

Product details

Factory M4 M5 M6 M8 M10 M12 Rubber Products Well Expansion Nut Motorcycle Windscreen Brass Insert Nut Blind Rivet Nut
