Nylon Pellet

A nylon pellet, similar to a nylon patch, serves as a locking feature on socket head cap screws to prevent loosening caused by vibration, shock, or other external forces. The nylon pellet is typically installed in a pre-drilled hole or cavity on the threaded portion of the screw during manufacturing. When the screw is tightened, the nylon pellet deforms under pressure and creates a frictional interface with the mating surface, effectively locking the screw in place.

Here's how a nylon pellet works:

1. Frictional Resistance: The nylon pellet deforms and expands when the screw is tightened, creating increased friction between the screw and the mating surface. This frictional resistance helps prevent the screw from loosening over time, even in dynamic or high-vibration environments.

2. Vibration Damping: By providing a cushioning effect and increasing surface contact between the screw and the mating surface, the nylon pellet helps dampen vibration and reduce the likelihood of self-loosening due to dynamic forces.

3. Reusable: Like nylon patches, nylon pellets offer locking functionality without permanently immobilizing the screw. This allows for the screw to be removed and reinstalled multiple times without compromising its locking ability.

4. Corrosion Resistance: In addition to providing locking functionality, some nylon pellets may also offer corrosion resistance, protecting the screw and the mating surface from environmental factors that could compromise their integrity over time.

Overall, nylon pellets enhance the reliability and security of socket head cap screws in applications where vibration, shock, or other dynamic forces are present. They provide a cost-effective and reusable solution for preventing loosening and maintaining the integrity of the fastened joint.
