Specification

SEODescription

The Big head carriage bolt M10x75 is a heavy-duty fastener designed for robust structural applications, featuring a large domed head with a square neck to prevent rotation during installation. This M10x75 carriage bolt has a 10mm diameter and 75mm shank length, engineered for high tensile strength (up to 800 MPa) using grade 8.8 steel with optional zinc plating for corrosion resistance. The 75mm carriage bolt operates effectively in temperature ranges from -20°C to 120°C, making it suitable for construction, machinery assembly, and agricultural equipment. Its key advantages include secure load distribution, vibration resistance, and compatibility with standard wrench sizes. However, the square neck requires precise square-shaped pre-drilled holes in materials like wood or metal, which may complicate installation in hard substrates. Ideal for permanent joints requiring non-slip performance.
