Professional Applications & Engineering Value
These M8 zinc plated steel flat washers provide critical engineering solutions where corrosion resistance and dimensional precision are paramount. The zinc plating creates a protective barrier against moisture and chemicals, significantly extending component life in outdoor equipment, automotive assemblies, and industrial machinery. Manufactured to DIN 125 and ISO 7089 specifications, these metric washers ensure perfect compatibility with M8 fasteners while the controlled thickness range (1.4-1.8mm) offers optimal surface pressure distribution. This prevents joint loosening, reduces stress concentration, and protects expensive components from damage - making them ideal for industrial applications requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
This flat washer features precise dimensional tolerances per DIN 125 and ISO 7089 standards with 8.4mm inner diameter, 16mm outer diameter, and 1.4-1.8mm thickness range. The zinc plated steel construction provides Rockwell B75 hardness for consistent mechanical performance. Manufacturing complies with international environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring safe use across global markets while maintaining the highest quality standards for industrial fastener applications.
