Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver critical protection in demanding environments where standard fasteners fail. The molybdenum-enhanced alloy provides exceptional resistance to chlorides, acids, and industrial chemicals, solving corrosion-related failure points in marine equipment, chemical processing plants, and offshore structures. The Rockwell B68 hardness rating ensures these inch-system washers maintain dimensional stability under sustained vibration and heavy clamping forces. With precise 0.531" ID and 1" OD dimensions, they create reliable bearing surfaces that prevent fastener embedding and distribute loads effectively across joined materials. The controlled 0.060-0.090" thickness range guarantees consistent spacing in assembled components, making them ideal for precision machinery, pump systems, and structural applications requiring predictable compression characteristics.
