![]() However, the welding nut is a kind of nut with relatively high strength, which can withstand various materials of different thicknesses, and its high temperature operation will cause the object to deform and cannot be disassembled. The purpose of the rivet nut is similar to that of the welding nut, both of which are used to firmly connect two objects together. It is easy to install, only needs to be simply riveted, and it is almost suitable for any metal that can be punched, but the scope of use is narrow, only for thin-walled plates, sheet metal, electronic or fine equipment connection. The riveting nut is simple to install, can be disassembled, easy to install and transport, etc. , magnesium, etc., need shielding gas or argon arc welding, and require processing technology and precision. These two have their own advantages and disadvantages, such as welding, the strength is relatively large, the thickness can be used, and the use range is wide, but due to the high temperature, the connected parts will be deformed and cannot be disassembled, and some active metals cannot be welded by ordinary methods, such as aluminum. , The nut is subjected to shear stress, so if the strength of the nut is not enough, it will be sheared and damaged, and the strength of the parent body will be plastically crushed and deformed. ![]() The contact surface is the contact stress, which means that the strength depends on the connecting piece and the parent body. The shape is circular, and one end has embossed teeth and guide grooves. The rivet nut is generally used on thin plates or sheet metal. The interior is the effect of molecular force, and the strength is generally greater than that of the parent body. The metal is melted at high temperature and mixed together and then cooled. Welding is equivalent to turning two separate parts into a whole. The purpose of welding and riveting nuts is to fasten and connect two objects together, so what are the differences between these two methods? The periphery of the hole is plastically deformed, the deformed object is squeezed into the guide groove, and then a locking effect is produced. Generally speaking, the diameter of the preset holes is slightly smaller than the embossed teeth of the pressure riveting nut. The principle is to press the embossed teeth into the preset holes of the sheet metal. Press rivet nut, also known as rivet nut, is a self-tightening nut with a round shape and an embossed tooth and a guide groove at one end. Friends who understand pressure riveting nuts may say that the use of pressure riveting nuts is similar to that of welding nuts, so what is the difference between the two? Pressure riveting nuts are also called self-tightening nuts, which are mainly used for the connection of materials such as thin plates or sheet metal. It does not have a unified national standard, but there are many different standards. The rivet nut is a common functional nut. ![]() There is also a welded nut, which is not easy to disassemble. It not only has good connection, but also simple operation and easy to disassemble. The rivet nuts are then widely used in various occasions because of the variety of their standards. What is the difference between a rivet nut and a weld nut ![]()
