Professional Applications & Engineering Value

This brass SAE flat washer addresses critical engineering challenges in precision assemblies where corrosion resistance and electrical conductivity are paramount. The 0.094" inner diameter provides exact compatibility with No. 2 screw sizes, eliminating play and ensuring secure fastening in compact electronic enclosures, instrumentation panels, and communication devices. The brass material naturally resists galvanic corrosion when paired with dissimilar metals, while its inherent conductivity makes it ideal for grounding applications and electrical connections. With SAE standardization and precise 0.25" outer diameter, these washers distribute load evenly across surfaces, preventing damage to delicate components and maintaining joint integrity in vibration-prone environments common to industrial controls, aerospace subsystems, and marine electronics.

Specification Summary & Compliance

This flat washer conforms to SAE standards with inch system dimensions: 0.094" ID, 0.25" OD, and controlled thickness range of 0.012-0.018". Manufactured from brass material for consistent performance, the washer is REACH (EC 1907/2006) compliant as of 06/14/2023, meeting environmental safety requirements while containing no SVHCs above threshold limits. The product maintains standard flat washer geometry suitable for general industrial applications requiring reliable spacing, load distribution, and surface protection.
