Conquest A563 Coupling Nut 5/8″ x 2-1/8″ Plain Steel

The Conquest 5/8″ x 2-1/8″ Coupling Nut provides a rugged and dependable solution for extending or joining 5/8″-11 threaded rod or bolts in interior construction, utility, or equipment assembly. Its uncoated plain steel finish makes it a practical option for dry environments where exposure to moisture is minimal. Precision threading and a hex body allow for a tight, aligned connection with easy installation using standard tools.

Plain Finish 5/8″-11 Coupling Nut for Threaded Rod Extensions and Bolt Joining

Built to meet ASTM A563 specifications, this coupling nut features coarse 11 TPI internal threads for compatibility with common 5/8″ hardware. Its extended body ensures secure thread engagement, providing structural support for HVAC framing, bracing systems, and equipment tie-ins. The hexagonal shape gives full tool access in tight or overhead environments, helping ensure proper torque during installation.

Key Features

• Designed for Rod Joining and Extension: Connects two 5/8″-11 threaded rods or bolts for extended reach and alignment.
• Carbon Steel Construction: Made to ASTM A563 standards for strength and reliability in mechanical builds.
• Thread Type/TPI: Internal 5/8″-11 coarse threads (11 threads per inch) ensure tight engagement with standard components.
• Corrosion Resistance: Plain finish is best suited for non-corrosive, indoor environments without moisture exposure.
• Hex Body: Allows for wrench-tightening in limited-access spaces for secure installations.

Applications

• Threaded rod extension in ceiling and channel framing
• Structural and utility rod alignment in dry environments
• Mechanical bracing in interior construction or facilities
• Joining heavy-duty bolts in machinery or suspended systems

Installation Tips

• Ensure both threaded rods or bolts use 5/8″-11 threading.
• Hand start before applying torque to prevent thread damage.
• Use a wrench on the hex flats to ensure a tight, flush fit.
• For exposed or outdoor use, choose galvanized or coated versions.
