The function of cold heading and riveting nuts

Cold formed press in nut is a special type of nut commonly used on metal sheets or thin-walled materials to provide a reliable threaded connection point. Its installation method is to press it into a pre punched plate through pressure, and use the plastic deformation of the plate to achieve fixation. The following are the specific functions and application scenarios of cold heading and riveting nuts:

1. Provide threaded connection points

Function: Provide a sturdy threaded hole on thin sheet materials, making it easy to use screws to connect or fix other components in the future.

Application scenarios: Widely used in industries such as automobile manufacturing, household appliances, office furniture, electronic devices, etc., especially in places where screws need to be installed on thin metal plates.

2. Enhance connection strength

Function: Cold heading and riveting nuts are tightly integrated with the sheet metal through their own structure, which can withstand large torque and tension, thereby enhancing the strength of the connecting parts.

Application scenario: Suitable for situations that require frequent disassembly or vibration loads, such as fixing interior parts of vehicles, assembling machine casings, etc.

3. Prevent thread damage

Function: As the board itself does not have threads, using cold heading rivet nuts can avoid thread damage caused by directly tapping on the board.

Application scenario: Cold heading rivet nuts can effectively protect the substrate and extend its service life on some soft materials (such as aluminum plates) or materials that are prone to thread damage (such as galvanized steel plates).

4. Simplify the assembly process

Function: Cold heading and riveting nuts are easy and fast to install, simply press them into pre drilled holes using a press or hand tool, without the need for additional welding or bonding processes.

Application scenario: On large-scale production lines, it can significantly improve production efficiency and reduce manufacturing costs.

5. Save space

Function: Compared to traditional welding nuts or other forms of threaded connections, cold heading and riveting nuts can achieve almost no protrusion on the surface of the plate, saving space.

Application scenario: In product design with strict requirements for spatial dimensions, such as internal structural components of portable electronic devices such as smartphones and laptops.

6. Improve production efficiency

Function: Cold heading and riveting nuts have fast installation speed, simple operation, and can quickly complete large-scale installation tasks.

Application scenario: Suitable for production lines that require assembly, especially in modern manufacturing industries with high levels of automation, which can significantly improve production efficiency.

7. Enhance fatigue resistance performance

Function: Due to its installation method being fixed by plastic deformation of the board, it can maintain good fatigue resistance during long-term use.

Application scenario: In situations where repeated stress needs to be sustained for a long time, such as various fixed parts in the engine compartment of automobiles, cold heading rivet nuts can provide reliable connections.

In short, cold heading rivet nuts play an important role in modern industrial production due to their easy installation, reliable use, and wide applicability. The correct selection and use of cold heading rivet nuts are of great significance for improving product quality and production efficiency.
