There are ASME, ASTM, DIN and other international standards that govern the nut sizes. The 3/4 Hex Nuts are some of the most commonly used nut sizes which is a medium size. The material grade is selected with the corrosion resistance, strength, wear and tear resistance and pricing of the material. The 304 Stainless Steel Hex Nuts are some of the cheapest available nuts with good strength and corrosion resistance. However, there are other material grades that have better corrosion resistance. The use of 304 Stainless Steel Slotted Hex Nuts is limited to less corrosive applications. For applications that need more resistance to salty air or chloride ion stress corrosion cracking, the 316 SS Hex Nuts are better. They are used in sea water, marine and other corrosive applications. Regal Sales Corporation is a leading manufacturer of hex nuts and Heavy Hex Nuts in different material grades, specifications and standards. Please feel free to contact us for more information and pricing of the Stainless steel metric hex nuts in various standards, dimensions and material grades.
