The NE Series Nylon Insert Lock Nut also referred to as a Nylok Nut, Stop Nut, Plastic Insert Lock Nut, Regular Series Nylon Lock Nut, Non-Metallic Insert Nut, Polyamide Lock Nut, or Nylon Insert Hex Nut is a nut with many identities but designed with one purpose. The Nylon Insert Hex Nut is a top-lock style with an elastic nylon ring. This ring grabs onto the thread as it’s fastened preventing the nut from loosening in vibrating applications.
