Nylon Insert Nut

Nylon insert nuts, also known as nyloc nuts, are specialized fasteners with a nylon ring or insert located inside the nut. This nylon ring acts as a locking mechanism that grips the threads of a bolt when tightened, providing resistance to loosening due to vibration or torque. Nylon insert nuts are frequently used in automotive, machinery, and construction applications to ensure a secure and vibration-resistant connection between bolts and components.
