Nylon Insert Lock Nuts
Nylon insert lock nuts — also known as nylock nuts — are threaded nuts with a nylon locking element that resists loosening from vibration, torque reversal, and shock. American Bolt Corporation supplies nylon insert lock nuts for mechanical, industrial, and manufacturing applications where reliable thread locking without additional hardware is required.
Nylock nuts are commonly used in assemblies where vibration or motion could otherwise cause standard nuts to back off.
What Is a Nylon Insert Lock Nut?
A nylon insert lock nut is a fastener with a nylon ring molded into the top threads. When threaded onto a bolt or screw, the nylon insert engages the mating threads, creating friction that helps prevent the nut from loosening under vibration or dynamic loading. Key attributes include:
- Reusable locking action (typical up to a limited number of cycles)
- No additional locking hardware needed (split lock washers or adhesives)
- Effective resistance to vibration and shock
Nylon insert lock nuts are widely used where thread security and ease of installation are needed.
