S-94610A215 0.125" ID x 0.375" OD Ultra-High-Temperature Ceramic Washers

Key Features & Benefits at a Glance

• Extreme temperature resistance up to 3000°F prevents deformation and maintains load distribution in high-heat industrial processes
• Exceptional electrical insulation properties of ceramic material prevent current leakage in electrical assemblies
• Precise dimensional tolerances (0.125" ID × 0.375" OD) ensure perfect fit and alignment for No. 4 screw applications
• Corrosion-resistant ceramic construction provides long-term reliability in harsh chemical environments
• Consistent thickness control (0.036-0.045") maintains uniform pressure distribution across fastened surfaces
• Environmental compliance with RoHS 3 and REACH standards ensures workplace safety and regulatory adherence
• Off-white ceramic composition offers visual distinction and non-contaminating properties for cleanroom applications

Professional Applications & Engineering Value

This ceramic flat washer delivers critical performance in extreme thermal environments where metallic washers would fail. The high-temperature ceramic material maintains structural integrity at temperatures reaching 3000°F, preventing thermal expansion mismatches that can compromise joint integrity. Engineered specifically for No. 4 screw applications, the precise 0.125" inner diameter and 0.375" outer diameter provide optimal load distribution while the ceramic construction offers excellent dielectric properties for electrical insulation. Ideal for furnace components, aerospace assemblies, power generation equipment, and semiconductor manufacturing where extreme temperature resistance and non-conductive properties are essential for operational safety and longevity.
