Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N825-004 is a galvanized steel threaded rod measuring 3/8 inch-16 thread pitch by 72 inches in length. It is designed for hanging, connecting, clamping, and supporting structural and mechanical assemblies across plumbing, heating, and electrical installations. The galvanized finish provides corrosion resistance and meets ASTM A307 Grade A and ASTM A153 standards. The rod can be drilled, cut, heated, or shaped on the job site, giving installers flexibility for custom-length applications. Licensed tradespeople and knowledgeable DIYers both reach for this hardware when a reliable, code-compliant threaded fastener is needed in demanding environments.

This threaded rod is suited for interior and exterior applications, including pipe hangers, conduit supports, HVAC duct work suspension, and general mechanical fastening tasks. Its Weatherguard Protection coating makes it a practical choice for installations exposed to moisture or outdoor conditions. A 3/8-16 thread pitch is a common standard size compatible with a wide range of nuts, coupling nuts, and hardware fittings used in plumbing and electrical rough-in work.

Installation Notes

Installation is typically performed by licensed plumbers, electricians, or HVAC technicians depending on the application. Shut off power or isolate the relevant system before securing supports or hangers. Standard hand tools and a hacksaw or angle grinder are sufficient for cutting to length on site. Follow applicable codes such as the NEC, IPC, or IFGC for hanger spacing and fastener requirements specific to the system being supported.
