Professional Applications & Engineering Value

These passivated 18-8 stainless steel flat washers deliver critical engineering value by addressing common industrial challenges including galvanic corrosion, surface degradation, and fastener failure. The passivation surface treatment creates a protective oxide layer that significantly enhances corrosion resistance in humid, chemical, and marine environments. Engineered specifically for No. 2 screw applications, these precision washers maintain consistent clamping force while preventing embedment in soft materials. The controlled thickness tolerance (0.016-0.025") ensures uniform pressure distribution across mating surfaces, making them ideal for aerospace assemblies, electronic enclosures, and precision instrumentation where vibration resistance and material integrity are paramount.

Specification Summary & Compliance
