Professional Applications & Engineering Value

This M16 zinc-flake coated steel flat washer delivers critical engineering solutions where corrosion resistance and mechanical strength are paramount. The zinc-flake coating provides exceptional protection against rust and chemical exposure, making it ideal for outdoor equipment, automotive assemblies, and industrial machinery exposed to moisture or aggressive environments. Its Rockwell B91 hardness ensures the washer maintains dimensional stability under high clamping forces, preventing deformation that could compromise fastened joints. The precise metric dimensions (17mm ID, 30mm OD) guarantee optimal load distribution across connected surfaces, reducing stress concentration and preventing material fatigue. Engineered to DIN 125 and ISO 7089 standards, this flat washer offers reliable performance in structural applications, heavy equipment manufacturing, and maintenance operations requiring durable industrial washers that withstand vibration and dynamic loads.
