Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver critical corrosion protection where standard fasteners fail. The marine-grade alloy withstands saltwater exposure, chemical processing, and outdoor applications without deteriorating. Engineered to ASME B18.21.1 specifications, these precision flat washers maintain consistent dimensions for reliable performance in industrial equipment, marine hardware, and food processing machinery. The optimized inner diameter (0.203") and outer diameter (0.406") create ideal bearing surfaces for No. 10 screw applications, preventing embedment while distributing clamp load effectively across joined materials. This combination of material excellence and dimensional precision solves common issues of fastener corrosion, joint failure, and maintenance frequency in demanding environments.

Specification Summary & Compliance
