Black oxidized hexagonal nut

The black oxidized steel Hex Nut is a Heavy Hex Nut with a black oxidized surface. Black oxidation treatment is a method of forming a black oxide film on the metal surface through chemical reaction, which can improve the corrosion resistance and mechanical strength of the metal.
Black oxidized steel hex nuts are typically made from carbon steel that has been cold-dip galvanized or hot-dip galvanized and then black oxidized. The black oxidation treatment can increase the corrosion resistance of the nut, making the Hex Flange Nut more suitable for use outdoors or in humid environments.
A black oxidized steel hex nut with six parallel sides, the Hex Nut can be used with Bolts to connect and secure a variety of parts. Hexagonal Nut is widely used in machinery, construction, automobiles, electronic equipment and other fields.
Generally speaking, black oxidized steel hexagonal nuts have the advantages of good corrosion resistance, high mechanical strength, and long service life, and are commonly used connecting components.
