Riveting nut column, also called riveting stud or nut column, is a kind of fastener applied to sheet metal, sheet metal, case and cabinet.
One end of the pressure rivet nut column is hexagonal, the other end is cylindrical, and there is a groove between the hexagon side and the cylinder, and the internal shape is internal thread.
Through the press to press the hex head into sheet of preset hole (preset hole aperture generally slightly greater than the pressure riveting screw cylinder diameter) to make plastic deformation around the hole, part of deformation is within the relief groove into pressure riveting nut column, the column pressure riveting nut rivet on the sheet, as to form the effective fixed on the sheet of internal thread.
Application Guide:
1. The selection of the nut column shall be based on the thickness of the plates used and the exact size range. The hardness of the low-carbon steel plate must be less than 70RB and the stainless steel plate less than 80RB.
2, free cutting iron surface treatment, stainless steel to keep the original color, according to the needs of the user can be ordered according to the table models and specifications, or according to the needs of special order.
3. The plate hole size must be processed according to the tolerance size of 0-+0.075mm. It is recommended to punch.
4, the installation must be achieved through "pressure riveting" operation, do not impact knock in.
5. When the material is stainless steel, the tail number should be marked with "S".
6. The end face of the nut column with straight teeth is denoted by "C".
7, under 10 mm hole nut column length are filled with silk, hexagonal end party in more than 10 mm (Ⅰ type) or endface reaming (Ⅱ type)
Rivet nut column can be divided into:
1. Quick cutting steel through-hole pressure riveting nut column SO type;
2. Stainless steel through hole riveting nut column SOS;
3. Quick cutting steel blind hole pressure riveting nut column BSO;
4. Stainless steel blind hole riveting nut column BSOS.
Apply to different use environment respectively.
Quick cutting iron surface treatment is generally galvanized, stainless steel is the natural color;
