Product Description

The Welding nails M4x8 are precision-engineered industrial fasteners designed for robust metal joining applications. These M4 welding nails feature a diameter of 4mm and a length of 8mm, constructed from high-grade steel or stainless steel with a zinc-plated surface for corrosion resistance. They operate within a 20-30V DC welding voltage range and withstand temperatures from -40°C to 200°C, ideal for automotive, shipbuilding, and structural engineering industries. The M4x8 welding nails deliver exceptional tensile strength (up to 800N) and shear resistance, compatible with automated welding systems via direct integration with robotic arms or welding controllers. Advantages include rapid installation and vibration resistance, though they require specialized welding equipment. Their compact design allows seamless integration with metal sheets, brackets, and structural components without additional adapters.
