Welding nuts is mechanical equipment closely connected parts, through the inside of the thread, the same specifications nut and screw, can be connected together, for example, the M4-0.7 nut only with M4-0.7 screw (in the nut, the M4 refers to the nut inside diameter is about 4 mm, 0.7 refers to the distance between the two thread is 0.7 mm).
The use of special welding materials such as aluminum alloy, stainless steel, mild steel with high strength, excellent welding performance characteristics.Welding nut, it is a nut, and bolt or screw fastening screw together to the function of parts, all production machinery must be an original, welding nut is mechanical equipment closely connected parts, through the inside of the thread, the same specifications welding nut and screw, can be connected together.
Above is what I share with you about the knowledge of the welding nut, hope will be helpful to you.
