• Superior electrical insulation properties due to the nylon plastic construction, preventing short circuits and enhancing safety in electrical assemblies.
• Excellent chemical resistance to withstand exposure to various substances, prolonging service life in harsh industrial conditions.
• Rockwell R118 hardness provides optimal durability and resistance to deformation under load, maintaining secure fastening over time.
• Precision metric sizing with 8.1mm ID and 12mm OD ensures a perfect fit for M8 screws, reducing installation errors and improving assembly efficiency.
• Lightweight and corrosion-proof nylon material reduces overall weight and eliminates rust, ideal for applications where metal washers are unsuitable.
• Full compliance with RoHS 3 and REACH regulations, guaranteeing environmental safety and meeting international standards for hazardous substance restrictions.

Professional Applications & Engineering Value

This M8 nylon plastic sleeve washer is engineered to address common challenges in electrical enclosures, automotive components, and machinery assemblies where electrical insulation, chemical exposure, and weight reduction are critical. The off-white nylon material offers inherent non-conductivity and resistance to oils, solvents, and UV degradation, preventing failures in sensitive applications. Its sleeve design with 19.05mm height acts as an effective spacer and bushing, minimizing vibration and wear while ensuring precise alignment for M8 metric screws. By maintaining integrity across a broad temperature range from -40°F to 180°F, it eliminates thermal expansion issues, reducing maintenance needs and enhancing the longevity of industrial and electronic systems.

Specification Summary & Compliance

This washer features precise dimensions: 8.1mm ID, 12mm OD, and 21.7mm overall height, with a sleeve OD of 9mm and height of 19.05mm, designed for M8 screw sizes in metric systems. It adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. The Rockwell R118 hardness confirms consistent material strength, suitable for standard industrial tolerances without additional certifications like ASME.
