M16 Type P Nylon Nuts, commonly known as nylon insert lock nuts or Nyloc nuts, are engineered to prevent self-loosening under vibration and dynamic loads. The integrated nylon insert grips the bolt thread, delivering consistent locking performance without damaging the threads. Finished with Trivalent Chromium (Cr3) zinc plating, these nuts offer enhanced corrosion resistance for internal environments. Ideal for construction, mechanical, and engineering applications, they are fully compatible with standard metric threaded bolts and studs.
