Professional Applications & Engineering Value

These nickel plated brass flat washers deliver critical engineering solutions where corrosion resistance and electrical properties matter most. The SAE standard flat washer design with precise inch system dimensions (0.094" ID × 0.25" OD) ensures perfect compatibility with No. 2 screw applications in electronics, instrumentation, and precision assemblies. The brass core provides natural antimicrobial properties and excellent conductivity, while the nickel plating creates a durable barrier against oxidation and chemical exposure. This combination addresses common failure points in electrical enclosures, marine equipment, and chemical processing installations where standard steel washers would corrode. The controlled thickness tolerance maintains consistent clamping force in vibration-prone applications, preventing loosening and maintaining long-term joint integrity.
