12Ga Aluminum CD Weld Stud Pins with Self-Locking Washer Marine Insulation Fasteners

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Marine Insulation Fixation: Designed to secure insulation materials in marine environments, offering corrosion resistance and vibration damping through self-locking washers.
  • Weld Stud Attachment: CD weld stud pins enable durable, permanent fixation in harsh conditions, ideal for insulating ship hulls, offshore platforms, and industrial equipment.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a combination of aluminum alloy and alloy steel, these fasteners resist corrosion in marine environments, outperforming standard steel studs in saltwater exposure*. The polished surface treatment further enhances durability and aesthetic appeal.

  • 2. Self-Locking Design for Secure Fixation

    • With integrated self-locking washers, you can achieve tight, vibration-resistant joints without additional locking components, saving time compared to traditional fasteners*.

  • 3. Versatile Length Range for Diverse Applications

    • With lengths spanning 100mm to 160mm, these fasteners accommodate thick insulation materials and structural applications, offering greater adaptability than shorter or fixed-length alternatives*.

  • 4. Marine-Specific Scenario Solutions

    • Designed for marine use, these fasteners withstand harsh saltwater conditions and temperature fluctuations, making them ideal for boat repairs or coastal construction compared to generic fasteners*.

  • 5. Polished Surface for Safety and Compliance

    • With a polished finish, these fasteners meet marine-grade standards for corrosion resistance and smooth installation, reducing the risk of splintering or rust-related failures*.

Supplier's note

  1. Technical Breakthroughs:

    • Composite Material: The Pro Model’s layered alloy steel and aluminum construction delivers 60% higher strength than base models while maintaining lightweight properties.
    • Dual-Layer Lock Washer: Reduces loosening risk by 50% compared to standard washers in vibration-heavy marine machinery.
    • Enhanced Coating: Pro Model’s coating provides 20% better corrosion resistance than industry benchmarks, critical for saltwater exposure.

  2. Version Selection Guide:

    • Base Model: Suitable for general marine insulation where weight savings are prioritized (e.g., lightweight boat construction).
    • Advanced Model: Ideal for high-stress environments (e.g., offshore platforms) requiring superior strength without sacrificing corrosion resistance.
    • Pro Model: Best for extreme applications like deep-sea equipment, combining unmatched strength, corrosion protection, and locking reliability.

With the Pro Model’s composite material, you can achieve 60% higher load capacity than traditional aluminum fasteners. With its dual-layer lock washer, you can eliminate 50% of post-installation maintenance in vibrating machinery.
