Top 10 Bolt Grade 8.8 Factory in China

Introduction to Bolt Grade 8.8

Bolt Grade 8.8 is a high - strength fastener grade widely used in various industries. The "8.8" in the grade designation represents its mechanical properties. The first digit "8" indicates that the nominal tensile strength of the bolt is 800 MPa, and the second digit "8" means that the yield strength ratio is 0.8. So, the minimum yield strength of a Grade 8.8 bolt is 640 MPa. These bolts are known for their excellent strength, durability, and resistance to deformation under high - stress conditions. They are commonly used in automotive, machinery, construction, and other applications where reliable fastening is crucial.
