Product Description

The M8x85 hex bolts, conforming to DIN 933 M8x85 bolts standard, are metric external hex head bolts designed for industrial fastening applications. These External hex head bolts M8x85 feature a 13mm wrench size, full 85mm length with a 1.25mm thread pitch, and are typically manufactured in steel grade 8.8 or stainless steel A2/A4 for corrosion resistance. Suitable for machinery, automotive, and construction industries, they operate reliably in temperature ranges from -50°C to +120°C. Surface treatments like zinc plating or hot-dip galvanizing enhance durability. Advantages include high tensile strength (≥800 MPa for grade 8.8) and standardized compatibility, while requiring proper torque tools for installation to prevent over-tightening. No integrated electronics – purely mechanical fasteners for structural joints.
