Professional Applications & Engineering Value
This M6 flat washer engineered from 18-8 stainless steel addresses critical challenges in industrial assembly where corrosion and mechanical stress compromise fastener integrity. The metric dimensions (13mm OD, 6.4mm ID) provide precise fitment with M6 fasteners, eliminating misalignment issues while the 2.0-2.9mm thickness ensures optimal load distribution across mating surfaces. In applications from machinery manufacturing to chemical processing equipment, the Rockwell B83 hardness maintains dimensional stability under vibration and thermal cycling, while the stainless steel construction prevents rust formation in humid or corrosive environments. These flat washers deliver consistent performance in automotive, marine, and food processing applications where material purity and corrosion resistance are paramount.
Specification Summary & Compliance
Manufactured to precise metric specifications with 6.4mm internal diameter and 13mm outer diameter, this M6 flat washer maintains dimensional accuracy for Class 2A fit applications. The 18-8 stainless steel composition provides consistent mechanical properties with Rockwell B83 hardness rating. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and material traceability for industrial use.
