Locking Patch Fasteners

Fasteners with a locking patch applied feature a pre-applied adhesive or nylon material on the threads, designed to increase resistance to loosening from vibration, shock, or thermal expansion. This patch creates friction between the mating threads, providing a reusable, self-locking mechanism that enhances joint reliability without the need for additional locking components like washers or nuts.

Locking patches can be applied to any type of male threaded fastener.
