A Nylock Nut, also known as a nylon insert lock nut, is a self-locking fastener designed to help prevent a nut from loosening due to vibration, movement, or repeated operation. It features a nylon insert positioned inside the upper portion of the nut. When the nut is tightened onto a bolt or threaded stud, the nylon insert creates additional friction against the mating thread, helping maintain a secure connection.
Nylock Nuts are widely used where reliable thread locking is required without the need for additional locking compounds or separate locking components. They are suitable for mechanical, automotive, industrial, engineering, and general fastening applications.
How Nylock Nuts Work
The nylon insert has an internal diameter slightly smaller than the mating thread. During installation, the bolt thread passes through the insert and causes it to deform around the thread.
This creates prevailing torque, which increases resistance to unwanted rotation and helps keep the nut securely positioned.
The locking action is achieved primarily through:
- Increased friction between the nylon insert and bolt thread
- Compressive force generated around the mating thread
- Resistance to loosening caused by vibration and movement
Nylock Nuts can also be removed and reused in suitable applications, although the effectiveness of the locking feature may decrease after repeated installation and removal. Their operating temperature suitability depends on the specific nylon material and application requirements.
