Professional Applications & Engineering Value
These M2.5 metric brass flat washers deliver exceptional engineering value in demanding applications where corrosion resistance and electrical conductivity are critical. The copper alloy composition prevents galvanic corrosion when paired with dissimilar metals, while the precise DIN 433 and ISO 7092 specifications ensure consistent performance in automotive, electrical enclosures, and precision instrumentation. The Rockwell B76 hardness maintains structural integrity under repeated assembly cycles, solving common failure points in vibration-prone environments. These precision washers provide reliable sealing surfaces and prevent fastener loosening in industrial machinery, marine equipment, and electronic assemblies where material compatibility and long-term reliability are paramount.
Specification Summary & Compliance
Manufactured to exacting DIN 433 and ISO 7092 standards with precise dimensional tolerances for M2.5 screw applications. Features a 2.7mm inner diameter, 5mm outer diameter, and controlled thickness between 0.4-0.6mm. The brass material achieves Rockwell B76 hardness for consistent performance. Fully RoHS 3 (2015/863/EU) compliant with exemption 6(c) for lead in copper alloys, meeting international environmental regulations while maintaining optimal material properties for industrial use.
