Can you tell me why it is that the 10.9 bolts are specifically colored black? Is there a particular reason for this choice of color, or is it just an arbitrary decision made by the manufacturer? I'm curious as to whether the color black serves a specific purpose, such as enhancing durability or making the bolts easier to distinguish from others. Could you provide some insight into this matter?

Among these methods, blackening and hot-dip galvanizing are commonly used for bolts rated above 10.9.

The risk of hydrogen embrittlement increases significantly when bolts are tightened after electro-galvanizing.

To mitigate this risk, bolts with a strength rating above 10.9 are typically not subjected to the electro-galvanizing process.
