Installation principle and scope of application of non-loosening screws

1. Installation principle of non-loosening screws:
   The anti-loosening screw is created by applying a layer of high-strength adhesive on the threaded surface of the screw shaft and utilizing heat treatment technology, enabling the screw to resist loosening under high-load conditions.
   The steps for installing a captive screw are as follows:
2. Ensure that the surfaces of the screw and the screw seat are dry and clean;
3. Apply the anti-loosening screw evenly on the threaded surface of the screw;
4. Use a standard tool to properly rotate the screw, ensuring it is installed parallel within the screw seat;
5. The captive screws need to be given adequate drying time before practical use.
   II. Scope of application of non-loosening screws:
   Loose-fitting screws are widely used in various mechanical and industrial fields under high-load conditions. For example, they are extensively applied in aerospace, automobile manufacturing, and the construction industry.
   In addition to stronger fixation performance, the non-backout screw also has the following advantages:
6. It allows for quick and easy installation, reducing installation time and costs;
7. It can be installed multiple times, reducing maintenance and replacement costs;
8. Compared to conventional screws, the non-detachable screws offer a higher cost-performance ratio and are more suitable for various application environments.
   In summary, the non-loosening screw is a highly practical fastener that can be applied for fixation under various stress conditions. During use, it is important to pay attention to the correct installation method of the non-loosening screw, as this can enhance its service life and effectiveness.
