M6*100 Carbon Steel Galvanized External Hex Bolts

Manufactured from medium carbon steel and heat-treated to Grade 8.8, these bolts achieve a minimum tensile strength of 800 MPa and yield strength of 640 MPa, providing a strong and cost-effective fastening solution for applications where moderate loads and good fatigue resistance are required.
The zinc galvanized surface finish delivers solid protection against rust and moisture in indoor industrial environments, on machinery frames, and in light outdoor use. The bright zinc layer also ensures smooth thread engagement with standard Grade 8 hexagonal nuts (DIN 934 or equivalent).
Available across a full range of grades (4.8 to 12.9, B7, L7, B8 series) and materials (carbon steel, alloy steel, and stainless steel), with surface options including Black oxide, HDG, Phosphate, PTFE, and Dacromet.
All products comply with DIN 931, ISO 4014, GB/T 5782, and related standards. OEM/ODM customization supported.
