Two Tongue Washer/double Tab Washer/OEM

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Fastening: The two tongue/double tab washer is designed to prevent loosening of bolts or nuts under vibration or torque, providing enhanced grip and pressure distribution.
  • Corrosion Resistance: Crafted from stainless steel, the washer ensures durability in harsh environments, resisting rust and oxidation.

Key features

  • 1. Corrosion-Resistant Stainless Steel Construction

    • With a stainless steel body and zinc/black surface treatments, you can ensure long-lasting durability in harsh industrial or outdoor environments. This outperforms traditional carbon steel washers in corrosion resistance*.

  • 2. Double Tab Design for Secure Fastening

    • With the dual tongue design, you can achieve precise alignment and secure locking in machinery or plumbing assemblies, offering better stability compared to standard flat washers*.

  • 3. Versatile Thickness and Thread Compatibility

    • With customizable thickness options (1in, 4mm, 6mm) and thread sizes ranging from M2 to M22, you can adapt to diverse mechanical requirements, providing greater flexibility than washers with limited size ranges*.

  • 4. Industrial-Grade Performance for Harsh Applications

    • With uniform thickness and metric-standard measurements, you can reliably use these washers in high-stress scenarios like automotive assembly or heavy-duty plumbing systems, surpassing consumer-grade alternatives in durability*.

  • 5. Material Compliance with Industry Standards

    • With stainless steel construction meeting corrosion and strength benchmarks, you can comply with safety and quality regulations in professional settings*.

Supplier's note

  1. Technical Breakthroughs:

    • Black Finish: Triple corrosion resistance vs. plain finishes, ideal for chemical plants.
    • Expanded Thread Range: 12 thread sizes (Pro) vs. industry standard 6, enabling universal bolt compatibility.
    • Metric Precision: 0.01mm thickness tolerance ensures minimal assembly gaps.

  2. Optimal Version Selection:

    • Base Model: Suitable for general machinery maintenance (e.g., automotive workshops).
    • Advanced Model: Preferred for marine or outdoor equipment with zinc finish for saltwater resistance.
    • Pro Model: Engineers designing heavy machinery benefit from 316L stainless steel and full thread compatibility.

Example: With the Pro Model’s 316L stainless steel, you can withstand temperatures up to 800°C—20% higher than industry benchmarks—making it perfect for aerospace engine components.
