Description

Conquest 5/8"-11 Grade C NE Nylon Insert Locknut – UNC, Plain

The Conquest 5/8"-11 Grade C NE Nylon Insert Locknut provides heavy-duty holding power in environments that demand vibration resistance and long-term fastening strength. Its 11 TPI UNC thread profile offers fast installation and strong grip, while the nylon insert helps eliminate loosening over time.

Heavy-Duty Locknut for Mechanical Frames, Panels, and Indoor Equipment

This locknut is forged from heat-treated Grade C steel and features a plain finish for clean, dry interior settings. Designed for mechanical and structural assemblies, it performs in service platforms, utility enclosures, access panels, and vibration-prone supports. The nylon insert offers frictional locking without damaging the mating threads or requiring thread lock compound.

Key Features

  • Nylon Insert: Locks securely and resists vibration-based loosening.
  • Grade C Steel: Heat-treated for higher torque and load resistance.
  • Thread Type/TPI: 11 TPI UNC coarse thread for quick installation.
  • Plain Finish: Intended for dry-use environments indoors.
  • Vibration-Resistant: Reduces maintenance and retightening.

Applications

  • HVAC system framing and duct supports
  • Indoor equipment and utility platforms
  • Machinery baseplates and mechanical anchors
  • Service panel structures and retrofit jobs
  • Use with 5/8"-11 coarse-thread rod and bolts

Installation Tips

  • Thread by hand before applying final torque.
  • Use calibrated tools for safe torque application.
  • Clean bolts and verify UNC thread match before install.
