Product Description

The Big Head Carriage Bolt M10x140 (also known as M10x140 Large Head Bolt or Square Neck Carriage Bolt M10x140) is a heavy-duty fastener with a large domed head and integrated square neck beneath to prevent rotation during installation. Designed for structural applications in construction, machinery, and automotive industries, it features M10 thread diameter, 140mm shank length, and high-grade carbon steel construction with zinc plating for corrosion resistance. Operating in temperatures from -20°C to 120°C, this bolt excels in load-bearing scenarios due to its robust tensile strength. The square neck ensures secure alignment in pre-drilled surfaces, though installation may require specific tools to accommodate its enlarged head profile. Ideal for permanent fixtures requiring vibration resistance and shear strength.
