In general, the hardness of stainless steel screws depends on the hardness of the stainless steel screw wire. With a good stainless steel screw material, the hardness must be stronger, and the difference is weaker. And 8.8 screws, usually purchased with 1018 screw wire, 10B21, and 45 steel screw wire to production, after the cold pier out of the screw, still need to hard treatment. The hardness reaches around HV450-550. If you say that you must compare which of the stainless steel screws and the 8.8-level screws are hard, it is reasonable to say that the 8.8-level screws are relatively harder and have a higher hardness index.
