S-96100A137 0.203" ID x 0.375" OD Plastic Washers

Key Features & Benefits at a Glance

• Superior electrical insulation properties from hard fiber material, preventing current leakage in sensitive applications
• Excellent corrosion resistance without metallic components, ideal for humid or chemically aggressive environments
• Maintains structural integrity under pressure with Rockwell R70 hardness rating for reliable load distribution
• Precise dimensional compatibility with 0.203" ID and 0.375" OD ensuring perfect fit for No. 10 screws
• Thermal stability up to 230°F allowing consistent performance in moderate heat conditions
• Regulatory compliance assurance with RoHS 3 and REACH standards for global industrial use
• Reduced galvanic corrosion risk as non-conductive fiber eliminates metal-to-metal contact

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these hard fiber flat washers solve critical challenges in electrical and mechanical assemblies. The non-conductive properties prevent short circuits in electrical equipment while the Rockwell R70 hardness ensures consistent compression resistance under bolt torque. With a 230°F temperature rating, they maintain dimensional stability in motor assemblies, transformer installations, and HVAC systems where thermal cycling occurs. The corrosion-resistant black hard fiber construction eliminates rust concerns in marine, chemical processing, and outdoor applications, providing reliable insulation between dissimilar metals to prevent galvanic corrosion. These inch-system washers deliver exceptional value in electrical insulation and vibration dampening while meeting stringent industry compliance requirements.
