National Mfg N179-309 Zinc Threaded Rod 10-24 X 12 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N179-309 is a zinc-plated threaded rod sized at 10-24 x 12 inches, designed for general-purpose fastening and structural support applications. The rod features UNC coarse threads throughout its full length and is fabricated to meet ASTM A37 Grade A standards, with a minimum tensile strength of 6 KSI. Its zinc finish provides basic corrosion resistance for light-duty indoor use. The N179-309 is sold in a package of two and is suitable for HVAC, plumbing, electrical, and general mechanical trade work where a machinable, workable threaded fastener is required.

This threaded rod is well suited for light structural hanging, equipment mounting, and general assembly tasks across residential and light commercial installations. The rod can be drilled, cut, heated, and shaped on the job site, giving installers flexibility when field modifications are needed. It is commonly used by HVAC technicians, electricians, and plumbers for hanging ductwork supports, pipe hangers, and electrical enclosures where a standard coarse-thread zinc rod fits the application.

Key Features

• UNC coarse thread pattern along the full 12-inch length
• Zinc finish for basic corrosion resistance in indoor environments
• Meets ASTM A37 Grade A with minimum tensile strength of 6 KSI
• Field-machinable: can be drilled, cut, heated, and shaped
• Sold as a package of two rods per unit

Compatibility

Designed as a general-purpose 10-24 UNC coarse-thread zinc threaded rod suitable for standard fastening and hanging applications across HVAC, plumbing, and electrical trades where a 12-inch zinc rod is specified.

Installation Notes

Installation is typically performed by HVAC technicians, electricians, or plumbers as part of support and hanging assemblies. De-energize any nearby electrical circuits and shut off system power before working in confined mechanical spaces. Standard hand tools and threading dies compatible with 10-24 UNC coarse thread are appropriate for field cutting or modification. Follow applicable local mechanical codes and manufacturer assembly guidelines when using threaded rod in structural support applications.
