1/4"-20 Conquest Heavy Hex Nut, A563 Grade A – Plain Finish

The 1/4"-20 Conquest Heavy Hex Nut is a high-quality, general-purpose fastener engineered for strength and durability. Constructed from medium carbon steel and finished in plain (uncoated) form, this nut is built to meet ASTM A563 Grade A standards—making it ideal for residential, structural, and light-duty mechanical applications.

Versatile Carbon Steel Heavy Hex Nut for Light-Duty Construction

This coarse-threaded nut features a 1/4" diameter with 20 threads per inch (TPI) and a larger body than standard hex nuts, providing improved wrench grip and bearing surface. Designed for compatibility with A307 threaded rod, Grade 55 rod, or general-purpose bolts, it excels in non-critical applications where value and function matter. Its plain finish is perfect for weldable assemblies or controlled environments where additional coatings aren’t required.

Key Features

  • Material: Made from medium carbon steel for strength in everyday fastening needs.
  • Thread Type/TPI: Coarse thread with 20 TPI for easy alignment and secure hold.
  • Heavy Hex Design: Oversized profile delivers greater surface contact and load-bearing capacity.
  • Finish: Plain (uncoated) surface ideal for welding or indoor use without exposure to elements.
  • Standard Compliance: Conforms to ASTM A563 Grade A requirements for dimensional and mechanical performance.

Applications

  • General residential or commercial construction
  • Light-duty machinery and framing connections
  • Low-stress structural assemblies and utility builds
  • Fabrication projects involving weldable components
  • DIY builds, brackets, and bolt-based repairs

Installation Tips

  • Pair with 1/4"-20 A307 or Grade 55 threaded rod or bolts for proper thread engagement.
  • Use a standard hex socket or wrench to apply even torque during tightening.
  • Clean the nut and mating threads before installation, especially if welding is planned.

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.
