Blind rivet nuts are divided into large countersunk head blind rivet nut , small countersunk head rivet nuts, flat head blind rivet nuts, round head blind rivet nuts, full hexagon blind rivet nuts, half hexagon blind rivet nuts and stainless steel blind rivet nuts. Rivet nuts, etc. can also be divided into knurled and non-knurled. The advantages of blind rivet nuts are easy to use, no noise, beautiful appearance, and replace the traditional welding nut process. At the same time, the installation space is small, and the work can be completed in a small space, which is more convenient to use than the installation of welding nuts and pressure riveting nuts.
Blind rivet nuts are widely used in the production and manufacture of internal parts such as automobiles, ships, elevators, etc. Mainly the connection between the boards. The rivet nut can be decorated on a single thin plate, or two thin plates can be riveted together, which is both a rivet and a rivet nut. Closed work pieces that can only be operated on one side are also suitable. In addition, the steel rivet nut is a compact threaded sleeve, which can be easily used for light metal work pieces that require screw and animal connections. Beautiful and easy to use, it is a low power consumption, high efficiency sheet metal rivet nut fastener product.
How to install countersunk head rivet nut on the board? The shape of the rivet nut column is hexagonal at one end and cylindrical at the other end. There is an undercut groove between the hexagonal side and the cylindrical shape. The internal shape is internal thread. Press the hexagon head into the preset hole of the thin plate with pressure. The diameter of the preset hole is usually slightly larger than the outer diameter of the clinch stud, which will cause plastic deformation around the hole, and the deformed part is squeezed into the undercut groove of the clinch nut to perform pressure. The rivet nut column is riveted on the thin plate to form an effective fixed internal thread on the thin plate. This is how it is installed.
