Professional Applications & Engineering Value

This ceramic flat washer delivers exceptional engineering value in applications where conventional metal washers fail. The high-temperature ceramic construction solves critical challenges in furnace systems, thermal processing equipment, and aerospace components by maintaining structural integrity at temperatures reaching 3000°F. Unlike metallic alternatives that oxidize or lose strength, these off-white inch-system washers provide consistent performance in corrosive environments and electrical insulation applications. The precise 1.125" OD and 0.469" ID dimensions ensure proper fit for 7/16" screws while the controlled thickness variation guarantees uniform clamping force distribution. Ideal for heat treatment fixtures, power generation equipment, and semiconductor manufacturing where thermal management and material stability are paramount.

Specification Summary & Compliance

This ceramic flat washer features inch-system dimensions with 1.125" outer diameter, 0.469" inner diameter, and thickness ranging from 0.056" to 0.071" for compatibility with 7/16" fasteners.
