1. Different materials
Galvanized screws are generally made of carbon steel and then galvanized for surface treatment. Stainless steel screws use different materials, usually stainless steel, which has higher corrosion resistance.
2. Different characteristics
Due to different materials, there are some differences in characteristics between galvanized screws and Flat-head Hexagon Socket Stainless Steel Screws. The thickness of the surface coating of galvanized screws is uneven. When rust occurs, the rust layer will corrode the galvanized layer and affect the protective effect of the rust layer; stainless steel screws can be used in humid environments without rust on the surface.
3. Different corrosion resistance
Since Concrete Screws are made of stainless steel, they are used in humid and corrosive environments, and their corrosion resistance is far better than that of galvanized screws.
4. Different usage scenarios
Due to differences in materials and characteristics, galvanized screws and stainless steel screws are also different in usage scenarios. Galvanized screws are suitable for non-humid and non-corrosive environments, such as wood connections, steel structure projects, etc.; while stainless steel screws are suitable for use in humid and corrosive environments, such as marine, chemical, food, and other industries.
Therefore, when selecting screws, it is necessary to select suitable materials and types according to the actual use environment and requirements to ensure the stability and durability of the screws during use.
