Description

A194 Grade 2H Heavy Hex Nut – 7/8"-9 Hot Dip Galvanized Steel

The Conquest A194 Grade 2H Heavy Hex Nut is engineered for heavy-duty structural and mechanical applications that demand strength, durability, and secure fastening. This nut is manufactured from medium carbon steel and heat-treated by quenching and tempering. This process enhances its tensile strength and hardness, making it an ideal fit for high-load environments such as industrial machinery, structural connections, and pressure-rated systems.

Hot Dip Galvanized 7/8"-9 Heavy Hex Nut for High-Stress Fastening

With a 7/8" diameter and 9 threads per inch (TPI), this nut features a coarse thread profile for secure engagement and simplified installation. The hot dip galvanized coating adds a robust layer of corrosion protection, making it suitable for outdoor use and environments exposed to moisture or chemicals. Conforming to ASTM A194 Grade 2H standards, this nut is built to perform reliably in high-pressure and high-temperature applications.

Key Features

  • Designed for High-Strength Use: Commonly used with A325 or A490 structural bolts and B7 threaded rods in demanding structural and industrial assemblies.
  • Material and Finish: Made from quenched and tempered medium carbon steel with a durable hot dip galvanized coating.
  • Thread Type/TPI: Coarse internal threading at 7/8"-9 (9 threads per inch) for strong and secure engagement.
  • ASTM Compliance: Meets ASTM A194 Grade 2H standards for use in high-pressure, high-temperature, and structural applications.
  • Heavy Hex Profile: Larger flats provide enhanced grip and increased surface contact for reliable torque application.

Applications

  • Structural steel connections using A325 or A490 bolts.
  • Threaded rod systems with Grade B7 fasteners.
  • Pipe flange and pressure vessel assemblies in demanding environments.
  • Outdoor and corrosive environments requiring heavy-duty rust protection.

Installation

  • Verify that the mating rod or bolt is threaded at 7/8"-9 for proper fit.
  • Begin threading by hand to ensure alignment and reduce cross-threading risk.
  • Use a wrench to apply torque on the heavy hex flats as specified.
  • Do not overtighten to preserve thread integrity and ensure consistent clamp load.
  • Follow relevant industry torque specifications for your application to ensure optimal performance.
