Set Screws Nylon Patch/Pellet

Socket set screws have a wide range of applications due in large part to their simplicity, effectiveness and precise connections. Mechanical applications will utilize set screws to prevent rotational changes and maintain proper alignment. If the environment is particularly volatile, some applications might call for a socket set screw with a nylon patch or nylon pellet. Both nylon patch and pellets are designed to prevent the screw from loosening; however, they differ in functionality and application. Both options are heavily utilized in applications with vibration or movement.
A nylon pellet is a small, cylindrical insert made of nylon. It is a separate component added to the threading of the screw. As the screw is installed and tightened, the nylon distorts causing friction and further securing the hold. Screws with nylon pellets may be multi-use so long as the user inspects the nylon to ensure no damage has occurred and the point type is one that will allow reuse.
A nylon patch is a coating applied to the screw’s threading during manufacturing. There are after-market options for thread locking material that can be applied on site; however, this option increases labor costs and installation time to allow for dry time. The nylon patches are often colorful to help the user easily identify the nylon patch from the bolt threads. It succeeds by creating friction between the bolt threads and base material. Screws with nylon patches may also be multi-use; however, the patch will wear over time and requires inspection. Consideration for point type is also required to determine if the set screw can be re-used.

- Black Oxide: Standard coating for socket products, offering a minimally protective layer on the bare steel. Beneficial for uniform color and reduced glare from the matte black appearance.
- Stainless-steel: Superior corrosion resistance with high durability.
