Professional Applications & Engineering Value
This copper flat washer delivers critical engineering solutions where electrical conductivity and corrosion resistance are paramount. Manufactured to SAE standards with inch measurements, it addresses common industrial pain points like galvanic corrosion and poor electrical grounding in assemblies using No. 2 screws. The copper material naturally inhibits oxidation while providing superior current flow, making these washers ideal for electrical panels, grounding systems, and electronic enclosures. Their flat washer design ensures even pressure distribution, preventing damage to soft materials and maintaining joint integrity in vibration-prone applications. The REACH compliance further supports use in regulated sectors including automotive, aerospace, and industrial equipment manufacturing.
Specification Summary & Compliance
This washer features precise inch dimensions with 0.094" inner diameter, 0.25" outer diameter, and thickness ranging 0.012-0.018". Manufactured to SAE standards for flat washers and compatible with No. 2 screw sizes. The product is fully REACH (EC 1907/2006) compliant regarding substance restrictions and SVHC requirements as of June 14, 2023. Copper material provides inherent corrosion resistance without additional surface treatments.
