Professional Applications & Engineering Value
This M16 square washer delivers critical engineering advantages in demanding applications. The galvanized steel construction provides essential corrosion resistance for outdoor equipment, marine hardware, and industrial machinery exposed to moisture and chemicals. The square geometry offers superior load distribution compared to round washers, preventing embedding in soft materials and reducing point loading on surfaces. With Rockwell B40 hardness, it maintains dimensional stability under heavy clamping forces, making it ideal for structural steel connections, heavy equipment assembly, and construction applications where vibration resistance is paramount. The metric dimensions ensure perfect compatibility with M16 fasteners in European and international engineering standards.
Specification Summary & Compliance
Manufactured to precise metric specifications: 22mm inner diameter, 50mm width, and 6.0mm thickness for M16 screw compatibility. The galvanized steel construction provides consistent performance with Rockwell B40 hardness rating. Fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as steel alloying element and REACH (EC 1907/2006) regulations (updated January 17, 2023, 233 SVHC), ensuring environmental and safety standards are met for industrial distribution and use.
