S-91145A241 0.201" ID x 0.437" OD Insulating Washers

Key Features & Benefits at a Glance

• Superior electrical insulation and corrosion resistance with Nylon 6/6 construction, ideal for preventing galvanic corrosion in mixed-material assemblies.
• Excellent dimensional stability with precise 0.201" ID and 0.437" OD, ensuring consistent fit and alignment for No. 10 screws.
• High impact resistance and durability due to Rockwell R108 hardness, reducing wear and tear in high-vibration environments.
• Wide operating temperature range from -40°F to 180°F, maintaining performance in both extreme cold and moderate heat conditions.
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting global environmental and safety requirements for industrial use.
• Lightweight and non-magnetic properties of the off-white nylon material, perfect for sensitive electronic and aerospace applications.
• Effective sealing and spacing function with sleeve design (0.281" OD, 0.046" height), protecting surfaces and distributing load evenly.

Professional Applications & Engineering Value

This Nylon 6/6 plastic sleeve washer is engineered to address common industrial challenges such as component misalignment, electrical shorts, and material degradation. Its sleeve design provides precise spacing and insulation, preventing metal-to-metal contact that can lead to corrosion or equipment failure. The Rockwell R108 hardness ensures long-term durability in high-stress environments, from machinery assemblies to electronic enclosures. With a broad temperature range of -40°F to 180°F, it performs reliably in outdoor or thermally variable settings, while the off-white color allows for easy inspection and identification. Ideal for No. 10 screw applications in automotive, HVAC, and consumer electronics, this washer enhances assembly integrity and reduces maintenance costs.
