Description

1"-8 Conquest Heavy Hex Nut, A563 Grade A – Plain Finish

The 1"-8 Conquest Heavy Hex Nut is built for large-scale fastening where high torque and structural strength are needed. Manufactured from carbon steel to ASTM A563 Grade A standards, this uncoated nut is designed for welding or dry-environment installation.

Oversized Hex Nut for Steel Framing and Anchor Systems

Its 1" diameter and 8 TPI coarse thread profile provide excellent strength and easy thread engagement. The heavy hex design increases surface contact, torque range, and load control—ideal for structural steel joints, support columns, and fabricated assemblies.

Key Features

  • Material: Carbon steel, uncoated (plain).
  • Thread Type/TPI: 8 TPI coarse thread for high-load systems.
  • Heavy Hex Design: Greater bearing area and torque resistance.
  • Finish: Plain for weld prep and dry storage.
  • Standard Compliance: ASTM A563 Grade A.

Applications

  • Heavy fabrication and structural steel
  • Anchor bolt hardware
  • Utility pole or cross-member assemblies
  • Indoor construction and framing
  • Maintenance or industrial repair

Installation Tips

  • Pair with 1"-8 rod or anchor bolts.
  • Apply torque using heavy-duty tooling.
  • Clean threads thoroughly before tightening or welding.

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.
