Nylon Patch

A nylon patch on a socket cap screw serves as a locking feature to prevent the screw from loosening due to vibration or other external forces. The nylon patch is typically applied to the threads of the screw during manufacturing, where it forms a frictional interface with the mating surface when the screw is tightened.

Here's how a nylon patch works:

1. Frictional Resistance: The nylon patch creates additional friction between the threads of the screw and the mating surface, making it more difficult for the screw to rotate or back out unintentionally.

2. Vibration Resistance: When subjected to vibration or other external forces, the nylon patch increases the resistance to loosening by maintaining consistent friction between the screw and the mating surface.

3. Reusable: Despite providing strong resistance to loosening, the nylon patch does not permanently lock the screw in place. This means that the screw can still be removed and reinstalled if needed, without damaging the threads or the mating surface.

4. Corrosion Resistance: In addition to providing locking functionality, some nylon patches also offer corrosion resistance, protecting the screw from environmental factors that could compromise its integrity over time.

Overall, the nylon patch on a socket cap screw enhances its reliability and security in applications where vibration or other dynamic forces are present. It provides a cost-effective and reusable solution for preventing loosening and maintaining the integrity of the fastened joint.
