S-95610A380 8.4 mm ID x 18 mm OD Plastic Washers

Key Features & Benefits at a Glance

• Excellent corrosion resistance with nylon plastic construction, eliminating rust issues in humid or chemical environments
• Superior electrical insulation properties prevent current leakage and short circuits in electrical assemblies
• Wide temperature tolerance from -40°F to 180°F ensures reliable performance in both freezing and elevated temperature conditions
• Optimal load distribution with precise 18mm outer diameter protecting surfaces from damage under M8 screw fastening
• Reduced assembly noise and vibration through nylon's natural damping characteristics
• Consistent dimensional stability with Rockwell R120 hardness maintaining shape under pressure
• Environmentally compliant with RoHS 3 certification for global industrial applications

Professional Applications & Engineering Value

These M8 metric flat washers solve critical engineering challenges where metal fasteners fail. The black nylon plastic construction provides inherent electrical insulation, making them ideal for electrical enclosures, control panels, and automotive wiring systems. Their non-conductive properties prevent galvanic corrosion when used with dissimilar metals, while the temperature resistance from -40°F to 180°F ensures reliability in outdoor equipment and machinery subjected to seasonal variations. The precise 8.4mm inner diameter ensures perfect fitment with M8 screws, preventing loosening from vibration in automotive, electronics, and industrial assembly applications. Unlike metal washers, these nylon flat washers won't scratch delicate surfaces, making them perfect for finished products and sensitive components.

Specification Summary & Compliance

Manufactured to precise metric dimensions with 8.4mm inner diameter, 18mm outer diameter, and 1.8-2.2mm thickness tolerance for consistent M8 screw compatibility. Constructed from Rockwell R120 hardness nylon plastic ensuring dimensional stability and wear resistance. Fully compliant with RoHS 3 (2015/863/EU) environmental standards, containing no restricted hazardous substances. The material specification supports continuous operation within the documented temperature range of -40°F to 180°F without degradation of mechanical properties.
