Learn some fastener knowledge every day. The technical guide for the application of rivet nut column is also called rivet nut column or nut column. It is a kind of fastener applied to sheet metal, sheet metal and machine ① according to the table box and cabinet of the national metrology verification system, the rivet nut column can be divided into so type of quick cutting steel through-hole rivet nut column, SOS type of stainless steel through-hole rivet nut column predicted by the mechanism There are four types of quick cutting steel blind hole rivet nut post BSO type and stainless steel blind hole rivet nut post BSOs type, which are respectively used in different service environments. Now I will introduce you to the technical guide for the application of rivet nut columns:

1. When selecting rivet nut columns, the size range must be determined according to the thickness of the plates used. The hardness of low carbon steel plates must be less than 70rb, and that of stainless steel plates must be less than 80RB. 2. Free cutting in 2017, our Jinan experimental machine factory will adhere to the principle of being a big manufacturer. The iron surface will be treated, and the stainless steel will remain the original color. Users can order according to the models and specifications in the table or make special orders 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 "riveting" operation, and must not be knocked in by impact

5. When stainless steel is selected as the material, the tail number shall be marked with "s"

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

7. The length of the through-hole press riveting nut column is less than 10mm, and the hole can be enlarged on the hexagonal end face (type I, we are confident to provide consumers with safe and convenient plastic materials that can make people's life more convenient) or the round end face (type II)
