Professional Applications & Engineering Value

These zinc-plated steel flat washers deliver critical engineering solutions for industrial assemblies requiring reliable load distribution and corrosion resistance. The metric flat washer design conforming to DIN 9021 specifications addresses common failure points in heavy machinery, construction equipment, and automotive applications where vibration and environmental exposure compromise fastener integrity. The zinc-plated steel construction creates a sacrificial barrier against oxidation while maintaining Rockwell B56 hardness for sustained performance under constant pressure. Engineered specifically for M16 fastener systems, these washers prevent joint relaxation and surface damage in high-stress environments, making them ideal for industrial maintenance and manufacturing operations where long-term reliability is paramount.

Specification Summary & Compliance

Manufactured to DIN 9021 dimensional standards with 17mm ID, 50mm OD, and 2.7-3.3mm thickness tolerance. Constructed from zinc-plated steel with Rockwell B56 hardness rating. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across global industrial markets.
