What is Nylon Insert Lock Nut? Properties, Dimensions and Uses

ByRachana Singh

Nylon insert lock nuts are a type of fastener that is used for a variety of applications. Often referred to as “jam nuts”, these specialized nuts are designed with an inner nylon locking element to keep them from loosening due to vibration or thermal cycling. This makes them perfect for use in machinery and vehicles, where vibrations can cause regular nuts and bolts to loose over time.

How Do They Work?

Nylon insert lock nuts work by pressing a nylon ring against the bolt thread and trapping it in place. The ring is usually made out of nylon, but other materials, such as plastic or rubber, may also be used. The friction between the ring and the threads ensures that the nut does not vibrate loose. This helps keep your connections secure, even under high vibration levels or when subjected to extreme temperatures.

Nylon Insert Lock Nut Uses

Nylon Insert Lock Nuts are great when you need a secure, permanently fastened joint. These nuts give superior hold and resistance to vibrational loosening, making them ideal for commercial production machinery and engine assembly applications. In addition to their typical use in construction and repairs, nylon lock nuts are also common parts for plumbing fixtures, air conditioning equipment, electronic devices and more. They come in many sizes so that any job can be completed to the highest security standards. Even in windy conditions or when exposed to vibration, these versatile fasteners provide reliably tight joints time after time.

Nylon Insert Lock Nut Properties

  • Nylon Insert Lock Nuts are easy to install and remove.
  • Nylon Insert Lock Nuts are resistant to vibration.
  • Nylon Insert Lock Nuts are self-locking.
  • Nylon Insert Lock Nuts are available in a variety of sizes.
  • Nylon Insert Lock Nuts can be used with various materials.

Advantages of Nylon Insert Lock Nut

The primary advantage of using nylon insert lock nuts is their ability to resist loosening due to vibration or thermal cycling. This makes them ideal for use in machinery, vehicles, and other applications where regular fasteners would be prone to coming loose over time. Additionally, they are generally more cost-effective than different locking mechanisms, such as safety wire or chemical adhesives requiring extra steps during installation. Finally, since they don’t require additional components (such as washers), they save time during assembly.
