Professional Applications & Engineering Value
Engineered for precision industrial applications, these M8 flat washers deliver critical engineering value through their black oxide steel composition and DIN 433 standardization. The metric dimensions (8.4mm ID × 15mm OD) ensure accurate alignment with M8 fasteners while the controlled thickness range (1.4-1.8mm) provides optimal surface pressure distribution. This prevents joint loosening in vibrating machinery and protects sensitive surfaces from galvanic corrosion. Particularly valuable in automotive assembly, electrical enclosures, and heavy equipment manufacturing, these flat washers solve common challenges of fastener erosion and dimensional inconsistency through rigorous manufacturing controls and RoHS/REACH compliant material selection.
Specification Summary & Compliance
Manufactured to DIN 433 standards with metric dimensional tolerances, featuring 8.4mm inner diameter, 15mm outer diameter, and 1.4-1.8mm thickness range. Constructed from black oxide steel for consistent performance in industrial environments. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted international trade applications.
