Welding nuts are divided into hexagonal welding nuts and square welding nuts according to their shapes. The materials are divided into carbon steel and stainless steel. They are generally used as internal thread of sheet metal. Welding nuts are welded to sheet metal by spot welding technology, and they are fixed to form an effective internal thread. Thread, welding nut with positioning feet, easy to weld, generally do not do any surface treatment, to maintain the welding performance of the nut, the welding nut production process is cold heading.

The purpose of the welding nut is the same as that of the riveting nut. It is used as a sheet metal internal thread. However, the principles of the two are quite different. , The precision of the pressure riveting nut and the strength of the riveting pressure may lead to the loosening of the pressure riveting nut, and the welding nut is welded by spot welding technology. Although the installation is more troublesome, the firm performance after welding is good and it is not easy to fall off.
