Why DIN912 hexagon socket screws usually black oxide?
First, black oxide is a common chemical surface treatment method. Its core principle is to form an oxide film on the metal surface to isolate the air and achieve rust prevention. For steel parts, black oxide can not only enhance corrosion resistance but also improve wear resistance to a certain extent, thereby extending service life.
Second, DIN912 hexagon socket screws are often used in high-strength connection occasions, such as automobiles, construction, and electronic equipment. In these applications, screws need to have good corrosion resistance and wear resistance. Black oxide can meet these requirements, provide reliable connection performance, and have a long service life. 2
In addition, black oxide is an economical and effective surface treatment method, especially suitable for occasions where appearance requirements are not very strict. It not only enhances the corrosion resistance of the screws but also improves their overall performance to a certain extent.
