5/8"-11 Conquest Heavy Hex Nut, A563 Grade A – Plain Finish

The 5/8"-11 Conquest Heavy Hex Nut is a medium carbon steel fastener designed for heavier-duty structural, framing, or utility connections. Conforming to ASTM A563 Grade A, this nut features coarse 11 TPI threading and a plain finish that allows for weldable, cost-effective performance.

Heavy Hex Nut for Framing, Bracing, and Utility Hardware

With its oversized hex profile, this nut delivers more contact area and clamping force than standard hex nuts—making it ideal for pole line hardware, utility builds, and indoor structural steel connections. Use with A307 or Grade 55 rod for dependable bolt assemblies in low-to-moderate stress environments.

Key Features

  • Material: Carbon steel construction with plain finish.
  • Thread Type/TPI: Coarse 11 TPI thread for strength and compatibility.
  • Heavy Hex Design: Wide flats allow high torque and better stress distribution.
  • Finish: Uncoated, suitable for welding or interior use.
  • Standard Compliance: Meets ASTM A563 Grade A.

Applications

  • Framing and base plate assemblies
  • Pole line and bracket mounting
  • Indoor structural or fabricated connections
  • Utility infrastructure and metal framework
  • DIY and repair work

Installation Tips

  • Match with 5/8"-11 threaded rod or bolts.
  • Apply torque with compatible socket or wrench.
  • Clean before use, especially for weldable connections.

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.
