Professional Applications & Engineering Value
This copper flat washer delivers critical performance advantages where standard steel washers fail. The copper material provides inherent corrosion resistance that eliminates galvanic corrosion in electrical panels, marine equipment, and chemical processing installations. Its excellent electrical conductivity makes it ideal for grounding systems, bus bar connections, and electrical substations where reliable current flow is essential. The SAE standard design ensures precise fit with 1" screws in heavy machinery, power generation equipment, and industrial assembly applications. The combination of thermal conductivity and durability addresses heat dissipation challenges in automotive and HVAC systems, while the RoHS and REACH compliance ensures suitability for regulated industries worldwide.
Specification Summary & Compliance
Manufactured to SAE standards with inch system measurements: 1.062" inner diameter, 2" outer diameter, and thickness ranging 0.108-0.160". This copper flat washer is engineered for use with 1" screw sizes and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The copper material provides consistent performance without hardness rating requirements for general industrial applications.
