You can compare different types: "Surface treatment of resin fastening screws."

You will understand the basics of "surface treatment" that improves the corrosion resistance and appearance of screws. This will explain the characteristics of representative surface treatments.

Metal screws, such as those made of iron, will corrode and rust due to electrochemical reactions after being molded for a while. Corrosion and rust can lead to poor appearance and reduced strength of the screws. To prevent such issues, surface treatment is applied to improve the rust and corrosion resistance of the screws. There are many types of surface treatment methods, each differing in functions such as corrosion resistance and appearance (color). It is necessary to choose the optimal surface treatment according to the purpose and usage environment. This document clearly explains the characteristics of commonly used surface treatments for screws: "Electrogalvanizing," "High Nickel Type - Zinc-Nickel Alloy Plating," and "GeometⓇ Treatment." It is a compact version that can be easily viewed.
