Pressure riveting stud that kind of material is cheaper

Pressure riveting nut column, also known as pressure riveting stud or nut column, is a fastener used in sheet metal, thin plate, chassis and cabinet. The appearance of pressure riveting nut column is hexagonal at one end, cylindrical at the other end, hexagonal edge and cylindrical in the middle of a back slot, its inner 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.

The rivet nut column can be divided into four types: quick cutting steel through hole pressure rivet nut column SO type, stainless steel through hole pressure rivet nut column SOS type, quick cutting steel blind hole pressure rivet nut column BSO type and stainless steel blind hole pressure rivet nut column BSOS type from the form of material and internal thread, which are applied to different use environments.

There is no specific national standard for rivet nut columns. The early manufacturers came from the United States, which gradually formed today's industry standard after being introduced into China. Most of the domestic manufacturers are from Suzhou in Jiangsu province and Dongguan in Guangdong Province

Shape standard:

Pressure riveting stud can be divided into two kinds of pressure riveting stud and blind hole pressure riveting stud according to the different requirements from the use. It is worth noting that the pressure riveting stud through hole to a certain length is the standard of half teeth through hole.

Material:

Carbon steel, medium carbon steel and stainless steel are used for the production of pressure riveting studs. The rivet nut columns made of carbon steel or medium carbon steel should be heat treated and surface galvanized or nickel plated. Carbon steel is cheaper!
