What grade is 304 stainless steel bolts?

304 stainless steel bolts are typically classified as Grade 18-8 or Grade 8.8. The term "18-8" refers to the composition of the stainless steel, which contains 18% chromium and 8% nickel. This provides excellent corrosion resistance and durability, making 304 stainless steel bolts suitable for use in a wide range of environments, including those with exposure to moisture, chemicals, and extreme temperatures.

In addition to the 18-8 designation, 304 stainless steel bolts can also be classified using the metric system as Grade 8.8. This refers to the strength of the bolt, specifically its tensile strength. Grade 8.8 bolts have a minimum tensile strength of 800 MPa (116,000 psi). This makes them suitable for use in various applications that require high-strength bolts.
