Professional Applications & Engineering Value
These zinc plated steel flat washers deliver critical engineering solutions for precision M2 fastener systems in electronics, automotive controls, and miniature mechanical assemblies. The Rockwell B76 hardness rating ensures permanent flatness under cyclic loads, while the zinc plating creates a sacrificial barrier against galvanic corrosion in mixed-material applications. Manufactured to DIN 433 and ISO 7092 specifications, these metric washers eliminate compatibility issues in international projects. The precise 4.5mm OD provides maximum bearing surface without overcrowding compact designs, making them ideal for PCB mounting, sensor housings, and precision instrumentation where corrosion resistance and dimensional accuracy are paramount.
Specification Summary & Compliance
This flat washer features metric dimensions with 2.2mm internal diameter, 4.5mm outer diameter, and 0.2-0.4mm thickness range. Manufactured to Class A precision tolerances per DIN 433 and ISO 7092 standards. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates. The zinc plated steel construction with Rockwell B76 hardness ensures consistent performance across industrial temperature ranges and environmental conditions.
