Product Description

The Big Head Carriage Bolt M12x50 is a heavy-duty fastener designed for robust industrial applications, featuring a large, domed head and square neck to prevent rotation during installation. With a diameter of 12 mm and a length of 50 mm (M12x50 Big Head Bolt), this bolt is constructed from high-strength carbon steel or stainless steel, offering corrosion resistance and tensile strength up to 800 MPa. It operates in temperature ranges from -50°C to +250°C, making it suitable for construction, machinery, and agricultural equipment. The Carriage Bolt M12x50 Big Head requires pre-drilled holes for installation and is compatible with standard M12 nuts. Key advantages include high load-bearing capacity, anti-loosening design, and durability in harsh environments, though precise alignment is needed during assembly. No electrical components or interfaces are integrated, as it is purely a mechanical fastener.
