Product Description

The Big head carriage bolt M6x30, also known as M6x30 large head carriage bolt, is a galvanized fastener designed for structural applications in construction and industrial equipment. This 30mm-long bolt features a 6mm diameter threaded shaft and an oversized domed head with square neck to prevent rotation during installation. The galvanized carriage bolt M6x30 offers corrosion resistance for outdoor or high-moisture environments. Typically used in wood-to-metal joining, trailer assemblies, and machinery frames, it withstands temperatures from -20°C to 120°C. Advantages include vibration resistance and tool-free head installation, though pre-drilling alignment holes may be required. The zinc-coated surface ensures durability while maintaining moderate conductivity for basic grounding applications in electrical enclosures.
