7/8"-9 Conquest A563 Grade DH Heavy Hex Nut – Hot Dip Galvanized, Wax, & Blue Dye

The 7/8"-9 Conquest A563 Grade DH Heavy Hex Nut is engineered for high-strength structural connections in critical steel construction and infrastructure projects. Manufactured from quenched and tempered carbon steel and coated with a Hot Dip Galvanized, Wax, & Blue Dye finish, this nut offers exceptional strength, corrosion resistance, and ease of installation. It meets ASTM A563 Grade DH standards for use with A325 and A490 structural bolts.

Heavy-Duty Structural Nut for Bridge, Utility, and Anchor Systems

With a 7/8" diameter and 9 threads per inch, this heavy hex nut delivers secure, load-bearing fastening in large assemblies. The heavy hex design increases surface area for torque and load distribution. Its blue dye aids in grade identification, while the wax minimizes friction during tightening. It’s an ideal choice for anchor bolts, structural joints, and threaded rod systems exposed to outdoor conditions.

Key Features

  • Material: Quenched and tempered medium carbon steel.
  • Thread Type/TPI: Coarse 9 TPI thread for reliable alignment and fastening.
  • Heavy Hex Design: Oversized profile for better load handling and torque application.
  • Finish: Hot Dip Galvanized, Waxed, and Blue Dyed for enhanced corrosion resistance and smoother installation.
  • Standard Compliance: Conforms to ASTM A563 Grade DH requirements.

Applications

  • Structural steel connections with A325 or A490 bolts
  • Bridge and highway construction anchor systems
  • Outdoor utility installations and heavy-duty framing
  • Steel-to-concrete base plates and supports
  • High-strength threaded rod systems in corrosive environments

Installation Tips

  • Use with 7/8"-9 galvanized A325/A490 bolts or structural-grade threaded rod.
  • Use heavy hex sockets to ensure proper torque transfer.
  • Allow the wax to aid in reducing installation friction and thread galling.
