  • nylon insert lock nut


Nylon Insert Locknuts, also known as Nyloc nuts, are self-clinching nuts characterized by a nylon ring that secures the nut to a threaded fastener. Nylon Insert Locknuts reduce the risk of loosening due to vibrations and movement, making them ideal for automotive and other high-motion applications. If you’re looking for a nut that will resist loosening and is easy to install, nylon insert locknuts are an excellent fastening solution.

Premium Nylon Insert Self-Clinching Nuts from EPCO Sales

Nylon insert locknuts are popular self-locking fasteners that consist of a hex nut with a fixed nylon collar ring. The nylon collar deforms elastically over the threads of a bolt, restricting movement from vibrations. Nylon insert lock nuts are ideal for use where a tight seal is needed or where repeated shaking could loosen a nut. Nyloc nuts also create a seal that helps prevent gases or moisture from passing through the threading of the nut. Nylon insert lock nuts should not be used in high-temperature environments exceeding 250° as the nylon portion of the nut can melt.
