Professional Applications & Engineering Value

This nickel plated brass flat washer delivers critical protection against galvanic corrosion in metric fastener systems, particularly valuable in electrical enclosures, marine hardware, and precision instruments where dissimilar metal contact occurs. The M5-compatible 5.3mm inner diameter provides exact screw clearance while the 10mm outer diameter creates optimal bearing surface. Brass construction offers natural antimicrobial properties for medical equipment while the nickel plating layer prevents oxidation in harsh environments. Engineers specify this corrosion resistant washer for long-term reliability in assemblies requiring consistent electrical continuity and regulatory compliance.
