Product Description

The M4x25 Welding Nails, also known as M4 Threaded Welding Nails or 25mm Welding Studs M4, are precision-engineered fasteners designed for secure metal-to-metal bonding in industrial applications. These studs feature an M4 thread diameter and a 25mm shank length, ensuring robust mechanical strength and compatibility with standard welding equipment. Constructed from high-grade steel with corrosion-resistant coatings, they operate effectively in temperature ranges from -40°C to 250°C, ideal for demanding environments in automotive, shipbuilding, and construction industries. Their threaded design allows direct integration with components requiring reinforced joints, eliminating secondary drilling. Key advantages include rapid installation, vibration resistance, and high tensile strength up to 500 MPa. Limitations include specialized welding tool requirements and alignment precision during application. Surface finish options include zinc-plated or stainless steel variants for diverse environmental conditions.
