N-LOC

Nylon Insert Prevailing-Torque Locknut

The N-LOC™ is an all-metal fastener designed to provide a secure, vibration-resistant connection across various applications. This locknut features a nylon insert that creates frictional interference with the bolt threads, ensuring the nut remains securely fastened without the need for additional locking devices.

The N-LOC™ locknut is engineered to maintain joint integrity under conditions involving continuous heavy vibration, shock, extreme temperatures, and numerous loading cycles. The nylon insert provides a reliable locking mechanism, preventing the nut from loosening over time. This design is crucial in applications where consistent clamping force is essential for safety and performance.

Application

The N-LOC™ locknut is suitable for a wide range of applications, including:

  • Automotive Industry: Securing components subject to constant vibration and dynamic loads.
  • Machinery and Equipment: Maintaining the integrity of assemblies in industrial machines operating under harsh conditions.
  • Construction: Providing reliable fastening solutions in structures exposed to dynamic forces and environmental stressors.
