Professional Applications & Engineering Value
This zinc plated steel flat washer delivers critical engineering solutions for industrial assembly challenges. The M18 flat washer design with DIN 125 and ISO 7089 compliance ensures precise fitment in machinery, automotive, and construction applications where vibration resistance and load distribution are paramount. The zinc plating provides sacrificial protection against corrosion, significantly extending the service life of bolted connections in exposed environments. With Rockwell B75 hardness, these metric flat washers maintain dimensional stability under sustained pressure, preventing joint failure in heavy-duty applications. The standardized dimensions (19x34mm) guarantee compatibility across global equipment specifications while the environmental compliance makes them suitable for regulated industries requiring RoHS and REACH compliant components.
Specification Summary & Compliance
Manufactured to DIN 125 and ISO 7089 standards with precise dimensional tolerances for M18 screw applications (19mm ID, 34mm OD, 2.7-3.3mm thickness). The zinc plated steel construction provides consistent performance with Rockwell B75 hardness rating. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and international market acceptance.
