Professional Applications & Engineering Value
These M2.5 metric flat washers deliver critical engineering solutions where corrosion resistance and dimensional precision are paramount. The passivated 316 stainless steel construction provides superior protection against chloride-induced stress corrosion cracking, making these DIN 9021 washers ideal for chemical processing equipment, marine hardware, and food processing machinery. The precise 2.7mm inner diameter ensures perfect alignment with M2.5 fasteners while the 8mm outer diameter maximizes bearing surface area, preventing fastener loosening under vibration and distributing clamp load effectively to protect sensitive materials. This combination of material excellence and metric system precision addresses common failure points in industrial assemblies, extending equipment service life while maintaining Rockwell B75 hardness for consistent performance.
Specification Summary & Compliance
Manufactured to DIN 9021 standard specifications with dimensional tolerances including 2.7mm inner diameter, 8mm outer diameter, and 0.7-0.9mm thickness range. These flat washers meet Rockwell B75 hardness requirements and comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in industrial applications worldwide.
