S-90097A213 8.1 mm ID x 12 mm OD Insulating Washers

Key Features & Benefits at a Glance

• Excellent electrical insulation and corrosion resistance due to nylon plastic construction, ideal for preventing galvanic corrosion in mixed-material assemblies.
• Superior vibration dampening and noise reduction compared to metal washers, protecting your M8 fasteners and components from loosening.
• Maintains integrity across a wide thermal range from -40°F to 180°F, ensuring reliable performance in both extreme cold and moderate heat environments.
• Precise fit and alignment with an 8.1mm ID and 9mm sleeve OD designed specifically for M8 screws, providing a secure and stable bearing surface.
• Durable and wear-resistant material with a Rockwell R118 hardness, offering long service life and resistance to deformation under load.
• Safe for regulated industries as it is fully compliant with RoHS 3 and REACH environmental standards, avoiding hazardous substances.
• Lightweight and non-marring properties help protect sensitive surfaces from scratches and damage during assembly.

Professional Applications & Engineering Value

This M8 nylon sleeve washer is engineered to solve common industrial challenges where metal fasteners are unsuitable. Its off-white nylon plastic construction provides essential electrical insulation, making it perfect for electronic enclosures and electrical panels. The sleeve design offers superior alignment and distributes load more effectively than flat washers, preventing pull-through in softer materials. It effectively dampens vibrations in machinery and automotive applications, reducing maintenance needs. The material's inherent resistance to many chemicals and its ability to perform in a temperature range from -40°F to 180°F make it a versatile choice for outdoor equipment, automotive assemblies, and food processing machinery where corrosion and contamination are primary concerns.

Specification Summary & Compliance

This metric sleeve washer is manufactured to precise dimensional specifications: 8.1mm Inside Diameter (ID), 12mm Outside Diameter (OD), 5.8mm Overall Height, and a 3.175mm Sleeve Height, ensuring a perfect fit for M8 screw applications. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free from restricted hazardous substances and safe for use in various global markets.
