Conquest A563 Grade A Coupling Nut 1-1/4″ x 3″ Zinc-Plated Steel

The Conquest A563 Grade A Coupling Nut is purpose-built for connecting or extending 1-1/4″-7 threaded rods and bolts. It provides a strong and secure solution for high-load applications that demand consistent performance and proper alignment. This coupling nut is commonly used in heavy-duty construction, industrial framing, and mechanical support systems where strength and reliability are essential.

Zinc-Plated 1-1/4″-7 Coupling Nut for Threaded Rod Extension

Engineered from carbon steel and coated in a corrosion-resistant zinc finish, this nut offers long-lasting durability in indoor or dry settings. Its precision-cut internal threads ensure accurate engagement between rods to maintain load stability. The hexagonal body is easy to grip with a standard wrench, enabling quick installation and dependable fastening without specialized tools.

Key Features

• Designed for Rod Joining and Extension: Ideal for connecting two 1-1/4″-7 threaded rods in framing, mechanical, or structural applications that require solid alignment and load-bearing strength.
• Carbon Steel Construction: Built to ASTM A563 Grade A specifications to provide high tensile strength and reliable thread performance under pressure.
• Thread Type/TPI: Features internal 1-1/4″-7 threads (7 threads per inch) for secure, vibration-resistant rod connections.
• Corrosion Resistance: Zinc-plated finish guards against rust and surface degradation in low-moisture environments such as interior construction sites or utility spaces.
• Hex Body: Designed for fast, tool-friendly installation using standard wrenches, saving time on the jobsite.

Applications

• Joining or extending 1-1/4″ threaded rods in mechanical and structural support systems.
• HVAC installations, ceiling grid assemblies, and industrial framing structures.
• Anchor rod extensions for equipment, scaffolding, or steel frame connections.
• Heavy-duty commercial and facility maintenance fastening projects.

Installation

• Ensure both rods are 1-1/4″-7 threaded to match the nut specifications.
• Thread each rod fully into the coupling nut to ensure maximum strength and thread engagement.
• Tighten the assembly using a wrench on the hex body for secure fastening.
• Do not overtighten to avoid damaging the threads or compromising performance.
• Ideal for low-vibration environments or static load-bearing installations.
