Flare-in nuts are special nuts used for connecting parts, also known as expansion rivet nuts, extrusion rivet nuts or expansion rivet buckles. It has a special design structure, which can realize fast connection with bolts through a series of mechanical principles, and is suitable for various metal and non-metal materials.

The advantages of rising rivet nuts mainly include the following points:
Quick and easy installation: The installation process of the rivet nut is relatively simple, just insert it into the hole with the appropriate tool, and then rotate the bolt to complete the connection. Compared with traditional nuts, rivet nuts do not require complicated thread processing and bolt rotation, which greatly improves installation efficiency.
High-strength connection: The expansion rivet nut adopts the mechanical principle to produce a high-strength connection with the bolt by forming a bite or expansion in the hole. This connection method has excellent anti-shear and anti-vibration performance, and can maintain a firm connection in various harsh environments.
No need for back processing: Compared with traditional nuts, rivet nuts do not need to be processed on the back of the connection, and do not require additional bolt lifting and support structures, saving time and cost. This is especially important for some application scenarios where backside processing is difficult.
Reliable sealing performance: Rivet nuts can provide reliable sealing perfor
