Professional Applications & Engineering Value
This M22 metric flat washer solves critical engineering challenges in heavy-duty applications where vibration resistance and corrosion protection are paramount. The black oxide steel construction provides superior rust resistance while maintaining dimensional stability under high clamping forces. Manufactured to DIN 125 and ISO 7089 specifications, these washers deliver consistent performance in industrial machinery, construction equipment, and automotive assemblies where precise load distribution prevents joint failure. The optimized 23mm internal diameter perfectly accommodates M22 screws while the 39mm outer diameter maximizes bearing surface area, effectively preventing fastener embedment and maintaining bolt tension in high-vibration environments.
Specification Summary & Compliance
This flat washer features precise metric dimensions with 23mm internal diameter, 39mm outer diameter, and controlled thickness range of 2.7-3.3mm. Manufactured in compliance with DIN 125 and ISO 7089 standards for dimensional accuracy and performance reliability. The product fully meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations (updated 06/14/2023, 235 SVHC), ensuring environmental safety and regulatory acceptance for industrial applications across international markets.
