Hexagon nut ISO 4032 Steel Zinc flake Cr(VI+)free - ISO 10683 flZnnc 10 M18

This hex nut is manufactured to ISO 4032 standards and made from Grade 10 steel, making it compatible with bolts and screws up to Grade 10.9. It features a metric thread and a Zinc Flake surface coating per ISO 10683 (flZnnc), which is Cr(VI)-free. This coating blends zinc and aluminum to deliver superior corrosion resistance compared to a pure zinc layer of the same thickness. Best of all, the coating process eliminates any risk of hydrogen embrittlement.
