5/16"-18 Conquest Grade 2 Hex Nut – Hot Dip Galvanized

The 5/16"-18 Conquest Grade 2 Hex Nut is a durable, general-purpose fastener made from carbon steel and coated with a corrosion-resistant hot dip galvanized finish. It features a coarse 18 TPI thread and standard hex profile, making it suitable for a wide range of light to medium-duty fastening applications. Whether used in framing, light utility builds, or maintenance tasks, this nut provides dependable holding power where high strength isn’t required.

Corrosion-Resistant Hex Nut for Framing, Utilities, and Light Structural Work

This nut is manufactured to ASTM A563 Grade 2 specifications and is intended for use with hot dip galvanized bolts and threaded rod such as A307 or Grade 55. The zinc coating provides protection against rust, making it ideal for outdoor or humid environments. Its hex design allows for easy installation using standard sockets or wrenches, while the coarse threading ensures strong engagement with minimal risk of stripping. This is a reliable choice for projects ranging from fencing and railings to bracing and low-stress support assemblies.

Key Features

  • Material: Low or medium carbon steel for versatile strength.
  • Thread Type/TPI: Coarse 18 threads per inch for secure fastening.
  • Hex Design: Six-sided shape offers tool compatibility for quick installation.
  • Finish: Hot Dip Galvanized for resistance to moisture and environmental exposure.
  • Standard Compliance: Conforms to ASTM A563 Grade 2 standards.

Applications

  • Fencing, railing, and outdoor wood/metal connections
  • Framing or support systems in utility or maintenance builds
  • Low-stress structural or base plate assembly
  • DIY or farm equipment repair tasks
  • Used with galvanized A307 or Grade 55 bolts and rod

Installation Tips

  • Use with 5/16"-18 galvanized bolts or threaded rod to ensure corrosion protection and thread match.
  • Apply proper torque using a wrench or socket sized for hex nuts.
  • Inspect threads for zinc buildup or debris before tightening.
