Metal Nuts

Weld Nuts

Weld nuts are specialized permanent fasteners engineered to be fused directly onto metal substrates via projection or spot welding, creating an integral threaded anchor point. They are typically manufactured from low-carbon steel to facilitate optimal electrical current concentration and melting at the weld projections, forming a high-strength bond that resists extreme torque and shear forces. These captive fasteners are critical in automotive chassis manufacturing, heavy industrial machinery, and thin-gauge sheet metal applications where access is limited to one side of the assembly.
