Professional Applications & Engineering Value

This ceramic flat washer is engineered to address critical challenges in high-temperature and corrosive industrial environments. Made from high-purity ceramic material, it provides outstanding thermal insulation and resistance to oxidation, making it indispensable in furnaces, aerospace components, and power generation systems where metal washers would degrade. Its flat washer design ensures even load distribution for No. 5 screw fastenings, reducing the risk of loosening under thermal cycling. The off-white color and inert properties also make it suitable for cleanrooms and chemical processing equipment, where contamination and reactivity are concerns. By integrating this washer, engineers can enhance equipment longevity, minimize downtime, and maintain performance in high-heat applications up to 3000°F.

Specification Summary & Compliance

This washer adheres to inch system dimensions with an inner diameter of 0.141", outer diameter of 0.406", and thickness ranging from 0.036" to 0.045", ensuring precise fit for No. 5 screw size applications. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmental safety and regulatory requirements. The ceramic construction is optimized for high-temperature resilience, with no specific hardness rating, focusing instead on thermal and chemical performance in demanding industrial settings.
