Description

Hex Lock Nuts NM NE Nylon Insert Steel Zinc 6/40 are high-security fasteners that combine rugged steel construction with a durable nylon insert to resist loosening under vibration.

  • Nylon insert locking mechanism provides vibration resistance and helps prevent nut backing off under dynamic loads.
  • Steel with zinc finish delivers strong load-bearing capability and corrosion resistance for indoor and light outdoor use.
  • Thread size: 6-40 UNC ensures compatibility with standard 6-40 fasteners common in many applications.
  • Hex head design allows easy tightening with common hand tools or power tools for consistent torque.

These nylon insert lock nuts are ideal for automotive, machinery, electronics enclosures, and general-purpose assemblies where reliable locking is essential. Use with matching 6-40 bolts to achieve optimal locking performance and prevent loosening from vibration or dynamic loading.

For best results, ensure proper torque and inspect for wear or damage over time to maintain secure fastening in your projects.
