Nylon Insert Lock Nuts, commonly known as Nyloc nuts, incorporate a nylon collar that resists turning. This nylon insert increases friction on the bolt threads, preventing the nut from loosening under vibration or torque. Unlike metal lock nuts, Nyloc nuts are limited to lower temperature applications due to the nylon material, which can degrade at high temperatures. These nuts are widely used for their reusability and reliable locking capabilities in dynamic environments. They are ideal for securing components that are subject to vibrations or dynamic loads, ensuring long-term reliability and safety.
