What Materials Are Hex Socket Boltss Made From?

Hex Socket Boltss are commonly made from stainless steel and inox. Among them, stainless steel screws have three common types:

+ Stainless Steel 201 screws have a low cost, good load-bearing capacity, but poor resistance to chemical corrosion. Therefore, they are mainly used for assembling toys and wooden products.
+ Stainless Steel 304 screws have high resistance to chemical corrosion, moderate cost, but lower load-bearing capacity compared to type 201. They are mainly used in shipbuilding, swimming pools, and wastewater treatment facilities.
+ Stainless Steel 316 screws overcome the disadvantages of the above two types by having both good corrosion resistance and load-bearing capacity. However, the cost of this type is relatively high.
