Description

A Nyloc nut is a type of locknut that has a nylon insert that prevents the nut from loosening. It's also known as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut. How it works The nylon insert is smaller than the thread diameter of the screw When the nut is tightened, the nylon insert deforms over the screw threads The deformation creates friction, which locks the nut in place Benefits Nyloc nuts are resistant to vibration and can be used in environments with high temperatures They can be used repeatedly without damaging the screw threads They can help seal the bolt thread to prevent leaks Applications Nyloc nuts are ideal for applications where vibration or motion could loosen the nut They can be used in automotive, aircraft, and rail applications Maintenance Nyloc nuts can be reused, but the locking feature will deteriorate over time Before using a Nyloc nut, inspect the nylon insert for damage
