Professional Applications & Engineering Value
This PEEK plastic flat washer delivers critical engineering solutions for demanding industrial environments where conventional metal washers fail. The high-temperature rating up to 500°F makes it ideal for automotive, aerospace, and chemical processing equipment exposed to thermal cycling. Its black PEEK material provides excellent resistance to chemicals, wear, and creep deformation, ensuring maintained clamping force in vibrating assemblies. The 5/8" internal diameter and 1.75" outer diameter create optimal bearing surface for 5/8" fasteners, preventing surface damage while distributing load evenly. These industrial washers solve common challenges like galvanic corrosion, electrical insulation requirements, and contamination in sensitive manufacturing environments.
Specification Summary & Compliance
This flat washer features inch system dimensions with 0.656" ID, 1.75" OD, and thickness range of 0.074-0.121". Manufactured to ASME B18.21.1 standards for dimensional consistency and performance reliability. The component is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant regarding substance restrictions, ensuring environmental responsibility and global market acceptance for your B2B operations.
