Product Description

The M5x40 welding nails are heavy-duty welding studs designed for robust industrial applications, featuring a galvanized weld fastener coating for enhanced corrosion resistance in harsh environments. These studs are engineered to withstand high tensile loads up to 4500 N and operate within a temperature range of -40°C to +250°C. Compatible with arc or capacitor discharge welding systems, they are widely used in automotive, shipbuilding, and structural steel industries. The M5x40 dimensions ensure optimal grip strength for metal sheets up to 6mm thickness. Advantages include rapid installation, uniform weld quality, and extended durability, though precise alignment is critical for performance. The galvanized finish provides additional protection against oxidation, making them ideal for outdoor or marine applications.
