The 304 stainless steel hex socket head cap screw is a mating nut for securing two connected parts through the through hole and assembly. Hex bolts are actually called multiple methods. For example, they can be referred to as hex screws. For example, they can be referred to as hex screws. Also known as a hex bolt. This is the same meaning. It’s just that personal habits are different. Hexagonal screws are the more common bolts. Used in environmental protection equipment, medical equipment, communication equipment, power facilities, electronic products, instrumentation, food machinery, petrochemical, ship assembly, pump and valve piping, building curtain wall, outdoor venues, sports facilities, outdoor decoration, etc., 304 stainless steel Very good corrosion resistance, can maintain long-lasting surface light, will 304 stainless steel hex bolts rust? 304 stainless steel screws do not necessarily corrode and rust, but stainless steel screws are more resistant to corrosion and rust than iron screws. However, stainless steel screws will still rust under certain conditions. Under what conditions, the hexagonal screw is easy to cause rust! What is the cause of rust? Stainless steel hex screws have better characteristics, strong smash resistance, high temperature resistance and strong rust resistance. However, it will rust even in harsh environments. For example, when the screws are very wet, they are exposed to the sun and the wind is blowing. After a long time, it will definitely produce rust. Contact with certain acid-base chemicals, such as chemical reactions. Causes corrosion and rust. There is also a stainless steel screw that is not good. For example, stainless steel SUS201 screws are used for seawater. Due to long-term immersion, the stainless steel 201 material itself is not suitable for use in salty seawater. Causes corrosion and rust. 316 stainless steel screws are generally recommended where it is often exposed to acidic environments or where there is seawater nearby, as 316 stainless steel screws are more resistant to corrosion.
