Pressure riveting nut column is also called pressure riveting stud or nut column. It is a kind of fastener used in sheet metal, sheet metal, chassis and cabinet. The shape of pressure riveting nut column is hexagonal at one end and cylindrical at the other end. There is an undercut groove between the side 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 (the diameter of the preset hole is generally slightly larger than the cylindrical outer diameter of the pressure riveting stud) Plastic deformation is generated on the periphery of the hole, and the deformed part is squeezed into the undercut groove of the pressure riveting nut column, so that the pressure riveting nut column is riveted to the thin plate, thereby forming an effective fixed internal thread on the thin plate.

The pressure riveting nut column is divided into fast-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 There are four types of BSOS-type rivet nuts, which are used in different environments.

There is no specific national standard for pressure riveting nut columns. The early manufacturers came from the United States, and they have gradually formed today's industry standards after being introduced into the country. Most domestic manufacturers come from areas such as Suzhou in Jiangsu and Dongguan in Guangdong.

Advantages of pressure riveting nut column:

SO (SOS) self-rivet type through-hole nut post is widely used in the inlay process of metal plates, control boxes and power cabinets and other product wall panels. The special structure of its structure, when assembling, only need to put the nut column into the hole of the metal plate, and realize it by "squeezing riveting" operation, which has the following advantages:

1. Realize the length guarantee of the distance range, greatly simplify the assembly process, and speed up the production progress of assembled spacing panels and accessories;

2. The back of the plate is kept completely flat, while ensuring that the head of the nut column and the plate are smooth;

3. The raw materials are free-cutting iron or free-cutting stainless steel;

Technical guide for pressure riveting nut column application:

1. When selecting the nut column, the actual size range must be based on the thickness of the plate used. The hardness of the low-carbon steel plate must be less than 70RB, and the hardness of the stainless steel plate must be less than 80RB.

2. The surface of the free-cutting iron is treated, and the stainless steel maintains the original color. Users can order according to the model specifications in the table according to their needs, or special order according to their needs.

3. The plate hole size must be processed according to the tolerance size of 0-+0.075mm, and punching is recommended.

4. The installation must be realized through "squeezing riveting" operation, and must not be impacted and knocked in.

5. When stainless steel is used as the material, the tail number is marked with "S".

6. The end face of the nut column with straight teeth is indicated by "C".

7. The length of the through-hole nut column below 10mm is full wire, and the hexagonal end face square (type Ⅰ) or round end face (type Ⅱ) can be reamed when the length is above 10mm.
