Professional Applications & Engineering Value
Engineered for demanding industrial environments, this 316 stainless steel flat washer delivers exceptional corrosion resistance where saltwater, chemicals, or moisture are present. The inch-system measurement ensures compatibility with North American machinery and existing 3/8" screw assemblies, while the precise 0.406" ID prevents misalignment and distributes clamping force evenly across surfaces. With its 1.25" OD creating an optimal bearing surface, this flat washer effectively prevents bolt head embedment and protects expensive components in marine applications, food processing equipment, and chemical processing systems where material integrity is critical.
