Professional Applications & Engineering Value

This M2 zinc plated steel flat washer delivers critical engineering solutions where corrosion resistance and electrical performance matter most. The zinc plating creates a protective barrier that withstands moisture and chemical exposure, preventing galvanic corrosion between dissimilar metals in industrial assemblies. Its precisely controlled 2.2mm inner diameter ensures perfect alignment with M2 screws while the 7mm outer diameter provides maximum bearing surface for superior load distribution. This prevents surface damage, reduces stress concentration, and maintains clamping force in electronic enclosures, automotive components, and precision machinery. The combination of steel core strength with zinc surface protection makes these metric washers ideal for applications requiring both mechanical reliability and environmental durability.

Specification Summary & Compliance

Manufactured to precise metric system standards with 2.2mm inner diameter and 7mm outer diameter dimensions, this flat washer maintains consistent 0.6-1.0mm thickness tolerance for reliable performance. The zinc plated steel construction follows industrial manufacturing specifications for flat washers. Fully compliant with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory acceptance for global industrial applications.
