Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Sealing & Insulation: Silicone/PVC/PA66 materials provide reliable sealing and electrical insulation for secure connections in plumbing, electrical, and mechanical systems.
  • Force Distribution & Cushioning: Flat circular design evenly distributes pressure under fasteners, preventing surface damage and ensuring tight seals in high-vibration or corrosive environments.

Key features

  • 1. Corrosion-Resistant PA66, PVC, and POM Materials

    • With corrosion-resistant PA66, PVC, and POM materials, ensure long-lasting performance in harsh environments. ~30% lighter than metal washers*, providing durable sealing in chemical or high-moisture settings.

  • 2. Ultra-Thin Design for Space Efficiency

    • With an ultra-thin profile, optimize space in compact machinery or electronic devices. 40% thinner than standard washers*, enabling precise integration in tight spaces without compromising structural integrity.

  • 3. Precision Thread Compatibility for Secure Fastening

    • Designed for M2/M3 thread sizes, deliver precise load distribution and sealing in small-bore applications. Ideal for electronics, PCB assemblies, or mechanical systems requiring insulation and durability.

  • 4. DIN Standard Compliance for Global Applications

    • Compliance with DIN standards ensures seamless compatibility with international engineering specifications, streamlining adoption in certified manufacturing or industrial workflows.

  • 5. Plain Surface Finish for Universal Adhesion

    • With a plain surface finish, ensure secure adhesion to diverse materials without interference. Reduces assembly errors in mass production and maintains stability in dynamic mechanical environments.

Product details

Din Standard M2 M3 PA66 PVC POM Plastic Fastener Round Flat Ring Plain Washers Thin Gasket Insulation clear Spacer Nylon Gasket

Din Standard M2/M3 PA66/PVC/POM Plastic Fastener Washers are precision-engineered sealing solutions designed for diverse mechanical, electrical, and automotive applications. With a plain black finish and standardized thread sizes (M2/M3), these washers ensure secure fastening, insulation, and corrosion resistance. Their versatile material options—PA66 (nylon), PVC, and POM (acetal)—allow tailored performance for specific operational demands.

Supplier's note

  1. Technical Breakthroughs:

    • PA66 Material: Achieves 60 MPa tensile strength, 40% higher than PVC, ideal for heavy-duty machinery.
    • POM’s Thermal Stability: Operates safely at 150°C, 20% hotter than PA66, for high-temperature systems.
    • Dielectric Strength: Both PA66 and POM meet 4KV insulation, enabling safe use in high-voltage electronics.

  2. Optimal Version Selection:

    • Base Model (PVC): Best for cost-sensitive applications requiring basic chemical resistance (e.g., plumbing).
    • Advanced Model (PA66): Perfect for automotive or industrial machinery needing durability and moderate heat resistance.
    • Pro Model (POM): Choose for aerospace or high-temperature equipment where rigidity and long-term stability are critical.

With POM’s 150°C resistance, you can safely seal engine components exposed to extreme heat. Pair PA66’s 4KV insulation with its 60 MPa strength to secure electrical connectors in industrial robots.
