Professional Applications & Engineering Value
Engineered for industrial fastening systems, these M5 zinc-plated steel flat washers address critical challenges in machinery assembly, automotive manufacturing, and structural applications. The zinc plating creates a sacrificial barrier against moisture and chemicals, significantly reducing corrosion-induced failures. With DIN 7349 compliance, these metric washers ensure dimensional accuracy across European equipment specifications, eliminating compatibility issues. The controlled 1.8-2.2mm thickness provides optimal surface bearing pressure distribution while maintaining space efficiency. This combination of corrosion resistance and mechanical reliability makes them ideal for industrial washers applications where vibration resistance and long-term fastener performance are paramount.
Specification Summary & Compliance
Manufactured to DIN 7349 standards with precise metric dimensions: 5.3mm inner diameter, 15mm outer diameter, and 1.8-2.2mm thickness range. Material hardness certified at Rockwell B76 for consistent performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
