Product Description
Automobile expansion nut is a kind of specially designed nut, which is usually made of metal or plastic, and has an expansion sleeve or expansion core inside it, which is used to expand the expansion part by tightening the bolt during installation, so as to fix the parts. Automobile expansion nuts are usually used to be fixed on thin-walled materials or non-metallic materials, such as plastic and glass fiber, to provide reliable connection and fixing effect.
The main functions of automobile expansion nuts include the following aspects:
1. Fixing on non-metallic materials: the automobile expansion nut is suitable for fixing on thin-walled materials or non-metallic materials, and the expansion part is expanded by tightening the bolts to form a firm connection, so as to ensure that the parts will not loosen or fall off under vibration or stress.
2. Disperse the fixing force: When the expansion nut is installed, the fixing force can be evenly dispersed on the surface of the fixed material through the expansion of the expansion part, so as to avoid the damage or fracture of the material caused by the concentrated fixing force and improve the fixing effect and service life.
3. Convenient installation and disassembly: The design of the automobile expansion nut makes the installation and disassembly more convenient and faster, and the fixing and unlocking can be realized by tightening and loosening the bolts, which reduces the time and cost of installation and maintenance and improves the work efficiency.
Generally speaking, the automobile expansion nut is a specially designed nut for fixing on nonmetallic materials. Its functions include fixing on nonmetallic materials, dispersing fixing force and facilitating installation and disassembly. It is an important part commonly used in automobile manufacturing and maintenance, which helps to ensure the stable connection and safe operation of automobile parts and improve the reliability and safety of vehicles.
