Aotian Precision Hardware analyzes the application of rivet nut column

Stainless steel rivet nut column, also known as rivet stud or nut column, is a fastener applied to sheet metal, sheet metal, chassis and cabinet. One end of the stainless steel rivet nut column is hexagonal in shape, and the other end is cylindrical. There is a knife retracting groove between the hexagon and the cylindrical center, and its internal form is internal thread, The hexagon head is pressed into the preset hole of the sheet by the press (the hole diameter of the preset hole is usually slightly larger than the cylindrical outer diameter of the rivet stud), causing plastic deformation around the hole. Some of the deformation is squeezed into the knife withdrawing groove of the stainless steel rivet nut column, so that the stainless steel rivet nut column is riveted tightly on the sheet, thus forming a useful fixed internal thread on the sheet. It is a fastener applied to sheet metal, thin plate, case and cabinet. One end of stainless steel rivet nut column is hexagonal in shape, and the other end is cylindrical. There is an undercut between the hexagon edge and the cylindrical shape, and its internal shape is internal thread. The hexagon head is pressed into the preset hole of the thin plate by a press machine (the hole diameter of the preset hole is generally slightly larger than the cylinder outer diameter of the rivet stud), causing plastic deformation around the hole, The deformed part is squeezed into the tool withdrawing groove of the stainless steel rivet nut column, so that the stainless steel rivet nut column is riveted tightly on the sheet, thus forming an effective fixed internal thread on the sheet.
The stainless steel rivet nut column can be divided into four types from the material and form of internal thread: quick cut steel through hole rivet nut column SO type, stainless steel through hole rivet nut column SOS type, quick cut steel blind hole rivet nut column BSO type and stainless steel blind hole rivet nut column BSOS type, which are respectively applied to different use environments.
Stainless steel rivet nut column defines the rivet stud or nut column. The advantages of the rivet stud or nut column are free cutting iron or free cutting stainless steel. The early manufacturers came from the United States and gradually formed today's professional standard after being introduced into China. 2. Advantages: SO (SOS) self riveting through hole nut column is widely used in the inlaying process of commodity wallboards such as metal plates, control boxes and power cabinets. Due to the particularity of its structure, during installation, it is only necessary to put the nut column into the hole of the metal plate and complete the "press riveting" operation, which has the following advantages: 1. The length of the distance scale is ensured, greatly simplifying the installation process, and accelerating the production progress of the installation distance panel and accessories;; 2. The back of the plate is completely flush, which together ensures the lubrication of the head of the nut column and the plane of the plate; 3. The raw materials are free cutting iron or free cutting stainless steel; The stainless steel rivet nut column is a standard fastener with internal thread from the surface shape. The screwing in direction of rivet screws is the exposure direction of such fasteners. Its types are: grounding stud; Quiescent stud; Expansion rivet stud; Kneading studs, reaming studs, double headed studs, and general studs.
