Description

5/8"-11 Conquest Heavy Hex Nut, A563 Grade A – Hot Dip Galvanized

The 5/8"-11 Conquest Heavy Hex Nut is a corrosion-resistant carbon steel fastener used in structural assemblies and anchor systems. Finished with hot dip galvanized zinc and built to ASTM A563 Grade A standards, this nut is perfect for projects exposed to the elements.

Reliable Galvanized Nut for Outdoor Structural Builds

Its coarse 11 TPI thread and oversized body give it better clamping power than standard hex nuts. Ideal for use with galvanized anchor bolts or threaded rod, it provides strong, long-lasting connections for decks, sheds, utility supports, and more.

Key Features

  • Material: Carbon steel with corrosion-resistant zinc coating.
  • Thread Type/TPI: 11 TPI coarse thread for secure, easy assembly.
  • Heavy Hex Design: Larger hex profile offers stronger grip and load spread.
  • Finish: Hot dip galvanized to withstand outdoor exposure.
  • Standard Compliance: Meets ASTM A563 Grade A performance criteria.

Applications

  • Exterior framing and support structures
  • Deck posts and base plates
  • Farm equipment and fencing
  • Outdoor anchor systems
  • DIY structural and repair projects

Installation Tips

  • Use with 5/8"-11 galvanized bolts or rods.
  • Clean threads before torqueing to remove any excess zinc coating.
  • Apply consistent torque using proper heavy hex tools.

Quality, delivery, prices excellent

I recently ordered some nuts, bolts, washers, screws, and ties for a pergola build. Their selection was great, product descriptions thorough, and delivery, and price excellent compared to other online stores and big-box stores. Will be buying from them in the future.
