Superior Quality: Robust protection of high-strength carbon steel
Learn more about the high-quality high-strength carbon steel material used in this hexagon socket head cap screw. This steel not only guarantees the hardness and strength of the product, but also provides excellent fatigue resistance. Compared with the common low-grade metal products on the market, it also shows higher stability and reliability under extreme environmental conditions.
The actual case shows that in the working environment of high temperature and humidity, ordinary bolts may rust or even break, but the high-strength carbon steel hexagon socket screws after special heat treatment can remain intact for a long time. This is due to the close arrangement of its internal structure, which makes the whole part have better toughness and ductility.

Black Aesthetics: Advantages of Surface Black Oxidation Treatment
Explore the reasons for using the black oxide process on the screw surface and the multiple benefits it brings. This technology not only gives the product a beautiful appearance, but also significantly enhances the corrosion resistance and wear resistance. The black oxide layer can effectively block moisture and other harmful substances from invading the substrate to prevent rust; at the same time, it can absorb light reflection, reduce dazzling interference, and make the work area safer and more comfortable.
In order to ensure long-term maintenance of the best condition, please pay attention to the following maintenance suggestions:
- -Use a clean soft cloth to gently wipe the surface stains;
- -Avoid contact with strong acid and alkali solution to avoid damage to the coating;
- -Store in a dry and ventilated place away from moisture sources.
