Professional Applications & Engineering Value
These M8 flat washers deliver critical engineering solutions where corrosion resistance and load distribution are paramount. The zinc yellow-chromate plated steel construction creates a robust barrier against moisture, chemicals, and oxidation—significantly reducing maintenance costs in industrial applications like machinery assembly, automotive components, and outdoor structures. With precise metric dimensions (8.4mm ID, 15mm OD) conforming to DIN 433 standards, these washers prevent bolt head embedding, distribute clamping forces evenly, and maintain joint integrity under vibration and dynamic loads. The Rockwell C38 hardness ensures consistent performance in high-stress environments while the flat washer design provides reliable seating for M8 screws across manufacturing and construction sectors.
Specification Summary & Compliance
Manufactured to DIN 433 specifications with metric dimensions: 8.4mm inner diameter, 15mm outer diameter, and 1.4-1.8mm thickness range. Material hardness certified at Rockwell C38 for consistent mechanical properties. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial and international applications.
