Professional Applications & Engineering Value

These silicon bronze flat washers deliver exceptional engineering value in applications where corrosion resistance is paramount. The silicon bronze material provides outstanding protection against saltwater degradation and chemical exposure, making these flat washers ideal for marine hardware, coastal infrastructure, and chemical processing equipment. The precise 0.392" ID ensures perfect alignment with 3/8" screws, preventing misalignment and distributing clamp load effectively across the 1" OD surface area. This combination of corrosion-resistant properties and dimensional accuracy solves critical failure points in industrial assemblies exposed to moisture, salt spray, and harsh environmental conditions, significantly extending maintenance intervals and reducing replacement costs.

Specification Summary & Compliance

Manufactured to inch system standards with precise internal diameter of 0.392" and outer diameter of 1", these flat washers maintain thickness tolerance between 0.055-0.069" for consistent performance. The washers are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet the latest environmental and safety standards for industrial components. The silicon bronze construction provides reliable mechanical properties without requiring additional surface treatments or coatings for corrosion protection.
