Technical Features
- Nylon insert construction: The integrated nylon collar grips the bolt thread, creating friction that resists loosening caused by vibration and torque without damaging the mating thread.
- 1-8 thread specification: The coarse 1-8 thread pitch provides compatibility with standard large-diameter fastener applications and allows for faster engagement and installation.
- Vibration-resistant locking mechanism: Unlike standard hex nuts, the prevailing torque design maintains clamp load in dynamic environments where movement and vibration are present.
Applications
- Mechanical and structural assemblies subject to vibration.
- Electrical and power supply installations requiring secure, stable fastening.
- General hardware applications where a reliable, reusable locking nut is required.
