If we need to use a nut on a thin iron sheet, because the iron sheet is too thin, it is not easy to tap and weld. At this time, we need to use a blind rivet nut or a pressure rivet nut. We all know that the hex rivet nut and other rivet nuts are widely used in the sheet metal industry. Rivet nuts are often used in our home life.
The hex rivet nut is made of galvanized iron, 304 stainless steel, and 316 stainless steel. The specifications supplied are M3-M12. The hex rivet nut is divided into flat head hexagonal blind rivet nuts and small head hexagonal blind rivet nuts, which are installed in the hexagonal bottom hole. Because of its hexagonal shape, it can completely prevent slippage and can withstand greater torque. After testing, even if the thread is damaged, the hexagonal rivet nut can still be firmly riveted on the thin plate. Its installation method is the same as that of ordinary circular riveting. The installation method of the nut is the same, except that when punching the bottom hole, it must be punched into a hexagonal hole that is compatible with it. The national standard number is GB/T17880.5.
The shape of the half hex rivet nut is slightly different from that of the hex rivet nut, and the purpose and installation method are very similar. www.khfastener.com
