How to select materials for stainless steel rivet nuts? Stainless steel rivet nut is a kind of nut applied to sheet metal or sheet metal, commonly known as sunflower nut, of course, it can also be called a cogged nut. Its overall shape is circular, and the front end of the primary PEM is provided with embossing teeth and guide grooves. Its principle is to press the embossed tooth into the preset hole of the sheet metal. Generally, the hole diameter of the preset hole is slightly smaller than the outer diameter of the embossed tooth of the stainless steel rivet nut. The embossed tooth of the stainless steel rivet nut is squeezed into the plate through pressure, causing plastic deformation around the hole, deformation is squeezed into the guide groove, and then locking effect occurs. The stainless steel rivet nut has four benefits: first, the plate does not adhere to complete flush; Secondly, all are small and exquisite, widely used in precision electronic and electrical products or precision equipment; It also has high torque resistance First of all, it is easy to equip, just press the rivet, standardize the serialization, and meet a variety of planning requirements; Stainless steel rivet nuts are generally used in the market more than iron ones. We all know that iron ones are called carbon steel ones. They are natural after being forged, turned or manufactured, and need electroplating. The stainless steel rivet nut does not need electroplating. In case of iron, the color of electroplating is generally decided by the customer, depending on what color the customer needs. There are also some pleadings for salt fog time. The salt spray time of some electroplating colors is higher, while that of others is less rust in a few hours. Another point is to see whether the customer needs to export this product. The export products generally need environmental protection. Some domestic products also need it, but most of them still do not need it. ​
