Professional Applications & Engineering Value
These nickel plated brass SAE flat washers deliver critical engineering solutions where corrosion resistance and electrical conductivity are paramount. The brass core material provides natural anti-galling properties while the nickel plating creates a durable barrier against moisture, chemicals, and atmospheric corrosion. Engineered to SAE standards with precise 0.406" inner diameter and 0.812" outer diameter, these washers prevent loosening under vibration and distribute clamp load effectively for 3/8" screw applications in electrical enclosures, marine hardware, and precision instrumentation. The controlled thickness tolerance ensures consistent performance in assembly operations, reducing installation time and improving joint reliability across industrial maintenance and manufacturing applications.
Specification Summary & Compliance
Manufactured to SAE standards in the inch measurement system with dimensional specifications: 0.406" ID, 0.812" OD, and 0.051-0.080" thickness range. These flat washers are compliant with REACH (EC 1907/2006) regulations (06/14/2023, 235 SVHC) for industrial safety standards. The nickel plated brass construction ensures consistent performance while meeting industry specifications for 3/8" screw applications in various engineering environments.
