Professional Applications & Engineering Value

This M30 flat washer delivers exceptional engineering value through its blue-dyed steel construction and precision metric dimensions. The 33mm ID x 58mm OD configuration provides optimal bearing surface for M30 fasteners, effectively distributing clamping forces in heavy machinery, structural steel connections, and industrial equipment assemblies. The blue-dyed surface treatment offers superior corrosion resistance compared to standard steel washers, making it ideal for applications where moisture, chemicals, or outdoor exposure are concerns. With Rockwell C38 hardness, this metric washer maintains dimensional stability under extreme pressure, preventing embedding and maintaining bolt preload in high-vibration environments. These characteristics make it particularly valuable for construction equipment, manufacturing machinery, and transportation infrastructure where reliability and longevity are critical.

Specification Summary & Compliance

This metric flat washer features precise dimensional specifications with 33mm inner diameter, 58mm outer diameter, and 3.4-4.6mm thickness range, engineered to ISO metric standards for M30 screw applications. The blue-dyed steel material provides enhanced surface protection while maintaining Rockwell C38 hardness for consistent mechanical performance. Manufacturing compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across industrial sectors without hazardous substance restrictions.
