This Rugged 12 Point Washer Nut usually has a natural metal surface treatment, such as ordinary carbon steel or stainless steel. If you want it to have stronger corrosion resistance, we can perform different surface treatments. For example, zinc yellow coating, zinc blue coating, black oxide coating or hot-dip galvanizing (this treatment will give it a distinct gray appearance).
These surface treatments not only protect the nut but also allow you to distinguish different uses or grades through color coding. Moreover, we usually pack them in large boxes, barrels or any custom packaging you require for delivery.
We’ve got 12-point washer nuts in different materials—like carbon steel, stainless steel (stuff like A2-70, A4-80), and aluminum.
For the carbon steel nuts, common coatings to keep them from rusting are zinc plating (usually with blue, yellow, or clear chromate), geometric zinc-flake coatings (those are for when you need better rust resistance), or black oxide. Which one you go with just depends on what the environment calls for.
And since the 12-point washer nut has a built-in washer, the coating stays undamaged where the nut touches the surface. That means it keeps protecting the nut the same way all through use.
