Product Description

The M4*16 welding nails, also known as Weld studs M4x16 or Hex base weld nails, are threaded fasteners designed for industrial joining applications via electric arc or capacitor discharge welding. Featuring a 4mm diameter and 16mm length, these hexagonal-base studs offer stable alignment during installation. They are compatible with automated welding systems, typically operating at 12-24V DC, and withstand operating temperatures from -40°C to 150°C. Widely used in automotive, shipbuilding, and structural fabrication industries, these nails provide high shear strength (up to 6000 N) and corrosion resistance through zinc-plated surfaces. Their hex base ensures secure grip for torque-sensitive assemblies, though proper surface preparation remains critical for optimal weld quality. The design enables rapid installation with consistent penetration depth in base materials ranging from 1-6mm thickness.
