This rod features a 1-1\/4-4 thread size with a 2C fit class and right-hand ACME thread form, ground to Precision ACME tolerances for consistent engagement and load transfer. Manufactured from Grade B7 alloy steel, it delivers high tensile strength and resistance to stress under demanding conditions. At 6 feet in length and 19.7 pounds, this rod is suited for fabrication, assembly, and installation work where standard threaded rod does not meet load or dimensional requirements.\u003c\/p\u003e\n\u003cp\u003eThis threaded rod is commonly used in HVAC structural support assemblies, mechanical equipment mounting, piping hanger systems, and general industrial fabrication. The ACME thread profile is preferred in power-transmission and linear-actuator applications where repeated axial loading is expected. Trades including pipefitters, millwrights, mechanical contractors, and HVAC installers rely on Grade B7 ACME rod for high-load hanger and support builds where standard hardware-grade rod would be undersized.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-4 ACME thread size with 2C fit class for consistent mating and controlled clearance\u003c\/li\u003e\n  \u003cli\u003ePrecision ACME thread form for reliable axial load transfer in power-transmission applications\u003c\/li\u003e\n  \u003cli\u003eGrade B7 alloy steel construction for high tensile strength in structural and mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eRight-hand single-start thread for standard installation with conventional nuts and mating hardware\u003c\/li\u003e\n  \u003cli\u003e6-foot length provides flexibility for field cutting and custom-length assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-format Precision ACME threaded rod for use with 1-1\/4-4 ACME-compatible nuts, flanges, and mating hardware in mechanical support and linear-motion assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanical or HVAC technicians familiar with threaded fastener standards and structural support requirements. Verify that all mating nuts and hardware carry a matching ACME 1-1\/4-4 2C thread specification before assembly. Cut to length using appropriate metal-cutting equipment and dress cut ends to remove burrs before threading on mating hardware.
