Product Description

The Big head carriage bolt M6x25, also known as Round head square neck bolt M6x25 or Heavy duty carriage bolt 6mmx25mm, features a 6mm diameter and 25mm shank length with a domed head and square neck for anti-rotation locking. Designed for industrial fastening in construction, machinery, and automotive assemblies, it operates under standard environmental conditions (-20°C to 120°C) without voltage requirements. The square neck integrates seamlessly with pre-drilled square holes in metal/wood surfaces, ensuring secure attachment. Advantages include high tensile strength (grade 8.8), zinc-plated corrosion resistance, and vibration-proof design. Limited to applications requiring flush-mounted fasteners due to its protruding head profile. Not compatible with dynamic load-bearing structures exceeding 500kg shear strength.
