Professional Applications & Engineering Value

This galvanized steel square washer delivers critical engineering solutions for heavy-duty industrial applications where corrosion resistance and load distribution are paramount. The M12 metric compatibility combined with the 50mm square profile creates an optimal bearing surface that prevents embedment in soft materials and distributes clamping force evenly across joints. The zinc galvanization provides sacrificial protection against rust and chemical exposure in manufacturing facilities, construction sites, and outdoor equipment. With its Rockwell B40 hardness rating, this metric square washer maintains dimensional stability under high torque applications, making it ideal for structural steel connections, machinery assembly, and automotive frameworks where vibration resistance is critical.

Specification Summary & Compliance

Manufactured to precise metric dimensions with 16mm inner diameter, 50mm width, and 6.0mm thickness for consistent performance. The galvanized steel construction meets industrial standards for corrosion protection while maintaining Rockwell B40 hardness for mechanical durability. Fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as steel alloying element and REACH (EC 1907/2006) regulations (including 233 SVHCs as of 01/17/2023), ensuring environmental responsibility and global market acceptance.
