Professional Applications & Engineering Value
These M5 flat washers deliver exceptional engineering value in demanding environments where corrosion resistance is critical. Manufactured from passivated 316 stainless steel, they effectively combat chemical degradation, saltwater exposure, and industrial contaminants that typically compromise fastener integrity. The DIN 9021 standardization ensures precise dimensional consistency, while the Rockwell B75 hardness maintains structural integrity under sustained loads. Ideal for industrial applications including marine equipment, chemical processing plants, and food machinery, these metric washers prevent galvanic corrosion and provide reliable performance where standard fasteners would fail prematurely.
Specification Summary & Compliance
This flat washer features precise metric dimensions with 5.3mm internal diameter, 15mm outer diameter, and 1.0-1.4mm thickness range, manufactured to DIN 9021 standards for dimensional accuracy. The 316 stainless steel construction with passivation surface treatment ensures superior corrosion protection. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and safety requirements for industrial components.
