rivet nut column
Pressing riveting means that in the riveting process, under the external pressure, the riveting part plastically deforms the base material, and is squeezed into the prefabricated groove specially designed in the riveted screw and nut structure, thereby realizing the reliable connection of the two parts. There are two types of non-standard nuts for riveting, one is a rivet nut column, and the other is a rivet nut. The use of such riveting forms to achieve the connection to the substrate, such riveting form generally requires the hardness of the riveted part to be greater than the hardness of the substrate. Ordinary low carbon steel, aluminum alloy plate and copper plate are suitable for crimping and riveting nut columns. For stainless steel and high carbon steel plates, because of the hard material, special high-strength riveting nut columns are required, which are not only expensive but also high in pressure. Difficult to connect, the crimping is not reliable, and it is easy to fall off after crimping. In order to ensure the reliability, the manufacturer often needs to weld on the side of the nut column, and the process is not good. Therefore, there is a sheet metal for the rivet nut column and the rivet nut. Parts are not as stainless steel as possible. This is also the case with rivet screws and rivet nuts, which are not suitable for use on stainless steel sheets
