Factory Custom Helmet Screw Cnc Lathe Nut Cnc Milling and Turning Bolt Pineapple Knurling Screw for Motorcycle Helmet

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Assembly: Designed to fasten motorcycle helmet components with precision, ensuring a secure and durable fit through knurled (pineapple-patterned) threading and CNC-machined accuracy.
  • Versatile Fixation: Supports standard thread compatibility and customizable finishes to adapt to diverse material and environmental requirements (e.g., saltwater resistance, high-temperature stability).

Key features

  • 1. Corrosion-Resistant Materials for Durability

  • With corrosion-resistant materials like 304 stainless steel and titanium, you can ensure long-lasting performance in harsh outdoor environments. These materials outperform standard steel in resisting rust and wear, ideal for motorcycle helmets exposed to moisture or chemicals.

  • 2. Ergonomic Pineapple Knurling for Secure Grip

  • The pineapple knurling design provides a textured surface, enabling precise adjustments without slipping. This interactive feature surpasses smooth-surfaced screws, making it easier to tighten or loosen in tight spaces.

  • 3. Versatile Material Options for Custom Performance

  • With materials ranging from lightweight titanium to high-strength steel, you can choose the optimal option for your application. For example, nylon or plastic variants offer cost-effective solutions, while bronze or brass enhance aesthetic compatibility with premium helmets.

  • 4. Compliance with Strict Environmental Standards

  • Certified to RoHS and EPR regulations (Germany/France), this screw ensures compliance with eco-friendly manufacturing and waste management standards, meeting stringent European market requirements.

  • 5. Modular Finishes for Aesthetic and Functional Adaptability

  • Choose from finishes like anodizing, zinc plating, or chrome plating to match helmet designs or enhance durability. The customizable surface treatments allow seamless integration into both industrial and consumer-grade products.

Supplier's note

  1. Technical Breakthroughs:

    • 304 Stainless Steel: With 25% higher corrosion resistance than steel, it outperforms in humid or salty environments.
    • Binding Head Design: Reduces slippage by 30% compared to standard hex heads, ensuring secure fastening.
    • Modular Finish System: Allows real-time customization of surface treatments to match both functional (e.g., anti-slip) and aesthetic needs.
  2. Optimal Version Selection:

    • Base Model: Ideal for budget-conscious users needing basic durability (e.g., casual motorcycle helmets).
    • Advanced Model: Best for marine or industrial applications where corrosion resistance is critical.
    • Pro Model: Tailored for racing gear or premium helmets requiring lightweight strength and advanced finishes.

Example Use Case: The Pro version’s titanium construction paired with a knurled grip ensures secure, vibration-resistant fastening in high-G-force scenarios, while its anodized finish withstands UV exposure during long-distance rides.
