Product Description

This heavy-duty M6x50 big head carriage bolt (also referred to as Large head M6 carriage bolt or M6x50 coach bolt big head) is a 6mm-diameter, 50mm-long fastener with an oversized domed head (20mm diameter, 8mm height) and square neck for anti-rotation security. Constructed from grade 5.8 carbon steel with zinc plating, it withstands temperatures from -30°C to 120°C and offers 800MPa tensile strength. Widely applied in construction, automotive, and industrial equipment assembly for structural connections requiring vibration resistance. The enlarged head distributes load efficiently, while the square neck locks into materials during installation. Primary advantages include corrosion resistance and high shear strength, though pre-drilled holes are mandatory. Limited compatibility with soft materials due to head protrusion requirements.
