First, let’s take a look at blind rivet nuts. Blind rivet nuts mainly contribute to the field of fasteners and have a wide range of applications. They are mainly used in the assembly and assembly of electromechanical and light industrial products such as aviation, furniture, automobiles, instruments, machines, and decorations. Riveted on. The main reason for the difficulty in distinguishing from the pressure riveting nut is that the purpose of the two is so similar that it is easy to confuse the two. However, the two are not the same. Metal sheet, thin tube welding nut is easy to melt, tapping internal thread is easy to slip teeth and other shortcomings are the most prone to problems during riveting. At this time, the blind rivet nut comes in handy. It does not need to tap internal thread, does not need welding nut, The riveting is firm, efficient, and easy to use.
Let's take a look at the pressure riveting nut. The function of the pressure riveting nut is actually the same as that of the blind riveting nut. It is a kind of nut used on thin plates or sheet metal. It has a circular shape and has embossed teeth and guide grooves at one end. . Generally speaking, the aperture of the preset hole is slightly smaller than the embossing teeth of the pressure riveting nut. The flower teeth of the pressure riveting nut are squeezed into the plate by pressure to cause plastic deformation of the periphery of the hole, and the deformation is squeezed into the guide groove, thereby Produce a locking effect.
  From the appearance point of view, the difference between blind riveting nuts and pressure riveting nuts is still very big, but their main functions are almost the same. They are all provided with threads for thin plates, but the installation method is different. The method of installation greatly determines the purpose and use of a nut.
  First of all, the installation method of the blind rivet nut is carried out by using a rivet gun, so it is suitable for use in places like square tubes and round tubes that are not easy to be riveted. Blind rivet nuts also make up for some of the shortcomings of electric welding, such as aesthetics, and places that are not easy to weld, such as thin plates. Blind rivet nuts are mostly used in some cabinets, square pipes and round pipes, fan production, equipment production, and zinc steel guardrails.
Let's take a look at the installation of the pressure riveting nut. The pressure riveting nut is also used on the upper side of the cabinet to provide the thread. Its operation method is to use a pressure riveting machine to perform pressure riveting. In this case, the requirements will be higher, and a riveting machine is required. The pressure riveting nut is very flat and will not have protrusions after being riveted to the upper edge of the thin plate. Pressure riveting nuts are mainly used in the production of some cabinets and cabinets, as well as in the production of equipment, water pumps, automobiles, and many other manufacturers.
    The installation of pressure riveting nuts is exquisite. If the installation method is not correct, the riveting will not be firm after pressure riveting. For example, one of our customers once reported that the nuts would fall off after riveting. Our technical staff found that many customers used hammers or other impact methods to knock them up, because the pressure riveting nuts would be compressed by this installation method. The uneven force of the rivet nut seriously affects the riveting effect. The surface appears to be pressed in, but in fact the teeth of the riveting nut are not riveted with the plate at all, so the riveting must be weak. The installation of pressure riveting nuts must use special installation equipment, or simply use presses and stamping equipment (generally factories will have these simple equipment).
To put it simply, the most intuitive difference between blind rivet nuts and pressure rivet nuts: the most important point is that blind rivet nuts can be used on top of finished and semi-finished products, while pressure rivet nuts must be used on the upper edge of the thin plate, and the finished product is used Pressure riveting nuts cannot be used because they are not suitable for the operation of pressure riveting machines. This is the main reason for the difference in the division of labor between the two. I hope you have a new understanding of the relationship between blind riveting nuts and pressure riveting nuts after reading this article. Being able to distinguish the difference between the two will bring a lot of convenience to your future work and reduce unnecessary losses.
