Professional Applications & Engineering Value

These zinc-plated steel flat washers deliver exceptional engineering value by solving critical industrial fastening challenges. The zinc plating creates a protective barrier against corrosion, significantly extending component life in moisture-prone environments while maintaining electrical conductivity. With precise 0.203" ID and 0.734" OD dimensions specifically engineered for No. 10 screws, these washers ensure perfect fitment and uniform load distribution across mating surfaces. The controlled thickness range (0.056-0.071") and Rockwell B40 hardness provide optimal compression resistance, preventing joint failure in vibration-intensive applications. Ideal for industrial machinery, electrical enclosures, and automotive assemblies, these ASME B18.21.1 compliant washers offer reliable performance where precision and durability are paramount.
