Specification

SEODescription

The Big head carriage bolt M6x60, also known as the M6x60 large head bolt, is a heavy-duty fastening solution designed for structural applications requiring enhanced load distribution. This carriage bolt with big head features a smooth, dome-shaped head (13mm diameter) and a square neck to prevent rotation during installation. With a total length of 60mm and M6 thread diameter, it offers a tensile strength of 400MPa (grade 4.8 carbon steel) and corrosion-resistant zinc plating. Commonly used in construction, agricultural machinery, and wooden structure assembly, its oversized head provides superior surface contact for wood-to-metal joints. Advantages include vibration resistance and tool-free head installation, though the prominent head profile may limit use in space-constrained environments. Operating temperature ranges from -20°C to 120°C, suitable for most industrial settings.
