Product Description

The M3x4 welding nails, also known as Welding studs M3x4 or M3x4 weld pins, are precision fasteners designed for industrial welding applications. These components feature a 3mm diameter and 4mm length, optimized for robust mechanical bonding in metal fabrication. Compatible with standard welding equipment, they operate within a 12-24V DC voltage range and withstand temperatures from -20°C to 150°C. Ideal for automotive, shipbuilding, and construction sectors, these weld pins enable direct integration with steel/aluminum substrates without additional connectors. Key advantages include high shear strength (>500N) and corrosion resistance, though precise alignment during installation is critical. Their compact size ensures minimal thermal distortion, making them suitable for confined spaces in structural assemblies.
