The hardness and strength of stainless steel 304 screws vary due to its diameter, length, manufacturing process and other factors, in general, the hardness and strength of stainless steel 304 screws are lower than ordinary carbon steel screws, but higher than some low-alloy steel screws.

The strength of stainless steel 304 screws usually includes tensile strength and shear strength, the tensile strength is generally between 70-85 ksi (thousand pounds/square inch), and the shear strength is generally between 40-50 ksi. At the same time, the hardness of stainless steel 304 screws is also low, usually between 70-90 Rockwell hardness B.

It should be noted that the strength and hardness of stainless steel 304 screws may be affected by a variety of factors, such as thread length, thread accuracy, installation method, etc. Therefore, when selecting and using stainless steel 304 screws, it should be evaluated and judged according to the actual situation to ensure that it meets the required strength and safety performance.

The hardness and strength of stainless steel 304 screws depend on their manufacturing process and material composition. Generally speaking, the hardness of stainless steel 304 screws is between HRC28-32, and the tensile strength is about 500-700MPa. However, these values are also affected by the manufacturing process and material quality, so the specific hardness and strength need to be tested and evaluated on a case-by-case basis.
