Key Features & Benefits at a Glance

  • Superior electrical insulation provided by Nylon 6/6 material, preventing current leakage and short circuits in sensitive assemblies.
  • Excellent vibration and shock absorption due to the plastic construction, reducing wear and loosening in dynamic applications.
  • Wide operating temperature resilience from -40°F to 180°F, ensuring reliable performance in harsh environmental conditions.
  • High mechanical strength and durability with Rockwell R108 hardness, resisting deformation under load for long service life.
  • Precise fit for No. 6 screws with 0.14" ID and 0.17" sleeve OD, ensuring easy installation and secure fastening.
  • Environmental and regulatory compliance with RoHS 3, making it safe for use in regulated industries and electronics.
  • Corrosion and chemical resistance inherent to Nylon 6/6, ideal for humid or chemically exposed environments.

Professional Applications & Engineering Value

This Nylon 6/6 Plastic Sleeve Washer is engineered to address common industrial challenges such as galvanic corrosion, electrical isolation, and component fatigue from vibration. Its sleeve design and off-white color provide both a physical barrier and visual identification, while the material's low moisture absorption maintains dimensional stability. Ideal for electrical enclosures, automotive assemblies, and machinery where non-conductive, vibration-resistant fastening is critical. The precise 0.14" ID and 0.29" OD ensure a snug fit on No. 6 screws, distributing load evenly and preventing fastener pull-through, thereby extending the lifespan of your products.

Specification Summary & Compliance

This washer conforms to standard inch system dimensions with an ID of 0.14", OD of 0.29", and thickness of 0.047". It is manufactured from Nylon 6/6 plastic with a hardness of Rockwell R108 and is fully compliant with RoHS 3 (2015/863/EU) regulations, ensuring it is free from hazardous substances. The temperature rating of -40°F to 180°F supports use in varied operational environments without loss of integrity.
