Product Description

The M8x40 welding nails are high-strength fasteners designed for robust industrial applications, featuring a diameter of 8mm and a length of 40mm. These M8 welding studs 40mm are engineered to withstand extreme mechanical stress, offering a tensile strength exceeding 500 MPa and operating reliably within a temperature range of -30°C to +250°C. Ideal for automotive, shipbuilding, and heavy machinery sectors, they provide seamless integration into metal structures via arc or resistance welding processes. The high-strength M8x40 nails are corrosion-resistant, coated with zinc or stainless steel for durability in harsh environments. Their precision-engineered design ensures minimal spatter and consistent weld penetration. While requiring specialized welding equipment, they excel in load-bearing applications due to their exceptional shear resistance and structural stability.
