Professional Applications & Engineering Value

These passivated 18-8 stainless steel flat washers deliver critical engineering solutions for industrial applications where corrosion resistance and dimensional precision are paramount. The passivation surface treatment significantly enhances the natural corrosion resistance of 18-8 stainless steel, making these washers ideal for marine, chemical processing, and outdoor equipment applications. With precise 0.188" ID and 0.375" OD dimensions specifically engineered for No. 8 screws, they ensure perfect fitment while the controlled thickness range of 0.036-0.065" provides optimal load distribution. This prevents surface damage to components and eliminates fastener loosening due to vibration or thermal cycling. The Rockwell B70 hardness ensures these washers maintain their structural integrity through multiple installation cycles, reducing replacement costs and maintenance downtime in industrial settings.
