Riveting nut column, also known as riveting stud or nut column, is a fastener applied to sheet metal, sheet metal, chassis and cabinet. The shape of riveting nut column is hexagonal at one end and cylindrical at the other. There is a knife retracting groove between the hexagonal side and cylindrical shape. Its inner shape is internal thread. The hexagonal head is pressed into the thin plate by a press. In the preset hole (the diameter of the preset hole is generally slightly larger than the cylindrical outer diameter of the riveting stud), the plastic deformation around the hole occurs, and the deformed part is squeezed into the retracting slot of the riveting stud, so that the riveting stud is riveted to the thin plate, thus forming an effective internal thread on the thin plate.

The riveting stud can be divided into through-hole riveting stud and blind-hole riveting stud according to different requirements. It is noteworthy that the through-hole riveting stud is the standard of through-hole half-teeth until a certain length. Pressure riveting nut column can be divided into four types: quick-cutting steel through-hole pressure riveting nut column SO type, stainless steel through-hole pressure riveting nut column SOS type, Fast-Cutting steel blind-hole pressure riveting nut column BSO type and stainless steel blind-hole pressure riveting nut column BSOS type, which are applied in different environments. There is no specific national standard for riveting nuts. The early producers came from the United States and gradually formed today's industry standard after being introduced into China. Most of the domestic producers come from Suzhou in Jiangsu Province and Shenzhen in Guangdong Province.
