✔️ M8x105mm Socket Bolt High Strength Grade 12.9 Carbon
M8 x 105mm hex socket head cap screws provide a secure, high-tension connection for heavy machinery, automotive repairs, and structural assemblies. These partially threaded bolts feature an internal hex drive for tight torque application and resist wear in demanding environments.
✅ Material: Grade 12.9 carbon steel with HRC 39-44 hardness for superior tensile strength and durability. ✅ Dimensions: M8 thread diameter with 105mm overall length and 30mm threaded section for precise fitment. ✅ Finish: Black oxide coating delivers corrosion resistance and reduces friction during installation. ✅ Drive Type: Internal hex socket compatible with 6mm hex keys, allowing high torque capacity in confined spaces.💡 Why Choose High-Torque Hex Socket Head Cap Screws for Mechanical Assemblies?
Heavy-duty fasteners like these deliver maximum clamping force while maintaining a handy low-profile shape suited for cluttered workspaces.
- Grade 12.9 carbon steel construction resists shear stress and maintains integrity under extreme mechanical loads and vibration hazards.
- Black oxide surface treatment protects against rust and corrosion while offering improved thermal stability for industrial component repairs.
- Fully hardened metallurgy ensures the bolt does not strip or stretch when subjected to high rotational torque during maintenance procedures.
