- Excellent electrical conductivity maintains reliable grounding and electrical connections in assemblies
- Precise dimensional fit with 0.812" ID specifically designed for 3/4" screws to prevent loosening
- Optimal load distribution through 1.5" OD design that reduces surface pressure and material stress
- Reliable sealing performance with controlled thickness range (0.108-0.160") for consistent gap filling
- Industry-standard compliance with SAE specifications ensuring interchangeability and quality assurance
- Environmental regulation adherence with REACH compliance for safe use in regulated industries
Professional Applications & Engineering Value
These nickel plated brass SAE flat washers deliver critical performance advantages in demanding applications where corrosion resistance and electrical conductivity are paramount. The combination of brass substrate with nickel plating creates a durable barrier against oxidation and chemical exposure, extending service life in marine, chemical processing, and outdoor installations. The precise 0.812" inner diameter ensures perfect alignment with 3/4" screws, preventing misalignment while the generous 1.5" outer diameter distributes clamping force effectively across joined surfaces. This makes them particularly valuable in electrical enclosures, plumbing systems, and machinery assemblies where both reliable fastening and electrical continuity must be maintained without compromise.
Specification Summary & Compliance
Manufactured to SAE standards in the inch system with precise dimensional tolerances, these flat washers feature a 0.812" ID and 1.5" OD with thickness ranging from 0.108" to 0.160". The nickel plated brass construction provides both functional and aesthetic benefits while maintaining compliance with REACH regulations (EC 1907/2006) as of June 14, 2023, ensuring they meet current substance restriction requirements for industrial use across regulated markets.
