Product Description

The M4x30 welding nails are precision-engineered fasteners designed for robust industrial applications. Constructed from high-grade stainless steel, these Stainless M4 welding nails offer exceptional corrosion resistance and durability under extreme conditions. With a nominal diameter of 4mm and length of 30mm, they provide reliable fixation in metal fabrication, automotive assembly, and structural engineering projects. The High-strength M4 nails are optimized for weld-on installation using standard M4 threading, capable of withstanding temperatures ranging from -40°C to 400°C and load capacities up to 8kN. Ideal for permanent joints in heavy machinery and construction frameworks, they feature a smooth shank design for precise alignment and reduced thermal distortion during welding. While requiring specialized welding equipment, their vibration-resistant properties and compatibility with carbon steels make them superior to conventional fasteners in high-stress environments.
