Professional Applications & Engineering Value

These M8 flat washers provide critical engineering solutions where corrosion resistance and load distribution are paramount. The zinc yellow-chromate plated steel construction effectively combats oxidation in demanding environments like outdoor machinery, automotive assemblies, and electrical enclosures. With precise dimensions (8.4mm ID, 16mm OD) conforming to DIN 125 and ISO 7089 standards, they eliminate fastener slippage and surface deformation under high vibration or thermal cycling. This makes them ideal for industrial applications requiring reliable, long-lasting fastening that withstands mechanical stress while meeting strict environmental regulations.

Specification Summary & Compliance

This flat washer features an inner diameter of 8.4mm, outer diameter of 16mm, and thickness range of 1.4-1.8mm, manufactured to DIN 125 and ISO 7089 dimensional standards for precise M8 screw compatibility. The Rockwell C38 hardness ensures consistent performance under load. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for regulated industrial and international markets.
