Product Description

The M4x20 industrial welding nails (model: welding nails M4x20) are robust fasteners designed for high-strength joining in demanding environments. These M4 welding nails with a 20mm length feature corrosion-resistant steel construction, supporting temperatures from -40°C to +300°C and operating voltages up to 48V DC in automated welding systems. Ideal for automotive assembly, shipbuilding, and structural steel fabrication, they ensure precise arc stability with ±0.2mm positional accuracy. Compatible with standard M4 thread interfaces, the nails integrate seamlessly into robotic welding modules via RS-485 or CAN bus protocols. Their tapered tip design enhances penetration depth up to 3mm in 10mm-thick materials. While offering exceptional shear strength (25kN), the 20mm M4x20 welding nails require specialized welding equipment for installation. Common applications include reinforcing cross-braces, panel bonding, and heavy machinery frame assembly where vibration resistance and permanent bonding are critical.
