The different composition, production methods and other mechanical and physical properties all matter. The SS 304 hex bolt is the most used in terms of the material grade as the 304 is a basic austenitic stainless steel with chromium and nickel composition. The torque strength is also good. The next most used is the ss 316 hex bolt due to the added corrosion resistance as it has molybdenum added to the content. The length of the bolts can range from 1 inch to 24 inches depending on the standard and application type. Some applications demand Stainless Steel heavy hex bolt due to the heavy load bearing nature. The bold diameter can range from ½ inches to 2 ½ inches depending on the standards such as the hex bolts din 933. The different standards are useful to maintain a universal measurement and identification of the bolts as they are used in different applications. The thread types, lengths, widths, head and other properties of the bolts vary with different standards such as the hex bolts din 931. The bolts are also specified for different applications such as fittings and flanges. There are differences to suit the connection types such as the hex flange bolts and hex fittings bolts. The fasteners also come with different standards for different use cases. To have an international measure, there are ISO numbers to indicate the types such as the hex bolt iso 4014.
