Product Description

The Big head carriage bolt M10x50, also known as the M10x50 coach bolt big head or Large head M10 carriage bolt, is a heavy-duty fastening component designed for robust industrial applications. With a diameter of 10 mm and a length of 50 mm, it features an enlarged domed head for secure, vibration-resistant installation. This bolt is typically crafted from grade 8.8 steel, offering a tensile strength of 800 MPa, and supports a maximum torque range of 40-50 Nm. Surface-treated with zinc plating for corrosion resistance, it operates effectively in temperatures from -20°C to 120°C. Widely used in construction, machinery assembly, and automotive frameworks, its key advantages include high load-bearing capacity, simplified alignment due to the square neck design, and durability under stress. Potential limitations include incompatibility with thin materials due to the large head profile. Ideal for securing structural joints, conveyor systems, and heavy equipment where shear strength and stability are critical.
