Conquest A194 Grade 2H Heavy Hex Nut 1-1/4″-7 Plain Steel

The Conquest 1-1/4″-7 Heavy Hex Nut is built to support the demanding loads of industrial framing, steel construction, and high-pressure systems. Made from medium carbon steel and heat-treated for maximum hardness and strength, this nut is a top choice for structural engineers and field professionals alike. Its plain finish offers a clean, economical option for use in indoor or sheltered installations where corrosion protection is not required.

Plain Finish 1-1/4″-7 Heavy Hex Nut for Structural and Pressure-Rated Applications

Featuring a coarse 7 threads per inch profile, this nut is designed to pair with 1-1/4″ diameter threaded rod and bolts. It conforms to ASTM A194 Grade 2H specifications, making it reliable for high-temperature and pressure environments. The oversized heavy hex shape provides a broad contact area for torque tools, ensuring secure installation with excellent wrench grip and load distribution.

Key Features

• Designed for High-Strength Fastening: Ideal for steel construction, industrial machinery, and high-load anchoring systems.
• Carbon Steel Construction: Quenched and tempered for mechanical strength and long-lasting performance.
• Thread Type/TPI: Internal 1-1/4″-7 coarse threads (7 threads per inch) ensure compatibility with matching threaded hardware.
• Finish Type: Plain steel finish for use in non-corrosive environments or interior setups where surface treatment is unnecessary.
• Heavy Hex Profile: Expanded wrenching area improves torque transmission and prevents rounding under pressure.

Applications

• Heavy structural steel connections using A325 or A490 bolts
• Equipment and machinery base installations
• Threaded rod assemblies in high-pressure systems
• Large-scale mechanical builds in protected environments

Installation Tips

• Verify correct thread match with 1-1/4″-7 threaded rod or bolts.
• Begin installation by hand-threading to avoid damage or misalignment.
• Use a torque wrench with flat-to-flat hex engagement for secure fastening.
• Limit use to indoor or shielded applications where rust protection is not a concern.
