Understanding 5 8 11 Hex Bolt Dimensions and Applications
Hex bolts specified as 5 8 11 hex bolt
indicate thread diameters of 5mm, 8mm, and 11mm respectively, with the M11 variant becoming increasingly popular in automotive applications. These fasteners typically adhere to DIN 933/931 standards, offering tensile strengths ranging from 8.8 to 12.9 grade. Industry data shows 11% annual growth in demand for M11-sized fasteners since 2020, particularly in electric vehicle battery frame assemblies.
Advanced Metallurgy in Modern Bolt Production
Premium hex bolts combine cold forging techniques with alloy blends containing vanadium (0.15-0.35%) and boron (0.0005-0.003%). This composition achieves:
- Rockwell hardness of C33-C39
- Shear strength up to 830 MPa
- Corrosion resistance exceeding 1,000 salt spray hours
