Technical Features

  • Nylon insert locking mechanism: The embedded nylon collar grips the bolt threads when tightened, resisting loosening caused by vibration and applied torque without the need for additional locking hardware.
  • Coarse thread profile: Coarse threading allows for faster installation and greater resistance to cross-threading, reducing assembly time in high-volume fastening tasks.
  • 5/8 sizing: Matches standard 5/8 coarse-thread bolt specifications, ensuring broad compatibility across common structural and mechanical assemblies.
  • Box quantity of 25: Bulk packaging reduces per-unit cost and ensures sufficient supply for multi-point fastening jobs without repeated reordering.

Applications

  • Structural assemblies subject to continuous vibration, such as machinery mounts and equipment frames.
  • General construction and fabrication where fastener loosening under dynamic loads is a concern.
  • Mechanical and industrial maintenance requiring reliable, reusable thread-locking fasteners.
  • Any application calling for a standard 5/8 coarse-thread nut with integrated locking capability.
