1/4"-20 Conquest Heavy Hex Nut, A563 Grade A – Hot Dip Galvanized

The 1/4"-20 Conquest Heavy Hex Nut is a general-purpose fastener engineered for strength, durability, and corrosion resistance. Constructed from medium carbon steel and coated with a hot dip galvanized finish, this nut is designed to perform in outdoor environments, structural connections, and light-duty mechanical applications. Built to ASTM A563 Grade A standards, it pairs seamlessly with bolts or threaded rod in a variety of projects.

Heavy Hex Nut for Construction, Utility, and Weather-Exposed Fastening

Featuring a 1/4" diameter and 20 TPI coarse threading, this nut is larger across flats and height than standard hex nuts, giving you more clamping force and wrench contact. The hot dip galvanized coating enhances corrosion resistance, making it a solid choice for exterior framing, fencing brackets, agricultural applications, or any bolt connection exposed to moisture.

Key Features

  • Material: Medium carbon steel with hot dip galvanized coating for enhanced corrosion resistance.
  • Thread Type/TPI: Coarse thread with 20 TPI for secure, vibration-resistant fastening.
  • Heavy Hex Design: Larger dimensions improve load distribution and torque application.
  • Finish: Hot Dip Galvanized for durability in outdoor or damp environments.
  • Standard Compliance: Conforms to ASTM A563 Grade A specifications for consistent performance.

Applications

  • Outdoor construction or residential framing
  • Utility brackets and fencing systems
  • Light-duty agricultural hardware
  • Moisture-exposed fastener assemblies
  • DIY or repair projects requiring corrosion resistance

Installation Tips

  • Use with 1/4"-20 hot dip galvanized bolts or threaded rod to avoid thread mismatch due to coating thickness.
  • Apply consistent torque using compatible sockets or wrenches sized for heavy hex flats.
  • Clean mating threads before installation to remove excess galvanizing or debris for smooth engagement.

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.
