The VALUE COLLECTION MSC-72047517 is a heavy hex nut threaded to the 3/4-10 UNC standard with a right-hand thread direction. Manufactured from Grade 2 steel and finished with a hot-dipped galvanized coating, this nut is suited for structural and heavy-duty fastening applications where corrosion resistance and load capacity are priorities. It measures 1-1/4 inches across the flats and stands 47/64 inches high. The larger flat-to-flat dimension of a heavy hex profile provides greater bearing surface compared to a standard hex nut, making it a common choice in structural steel connections, anchor bolt assemblies, and high-load mechanical joints. Licensed tradespeople and maintenance professionals working with structural fasteners are the primary installers.
This heavy hex nut is used in residential and commercial construction, industrial equipment assembly, and infrastructure applications where UNC-threaded fasteners are specified. The hot-dipped galvanized finish provides a zinc coating that resists oxidation in outdoor, wet, and moderately corrosive environments. It is appropriate for use on galvanized or plain steel bolts and threaded rod in structural assemblies, anchor systems, and equipment mounting applications that call for a heavy hex profile per ASTM or equivalent specifications.
Designed as an OEM-style replacement or new-installation heavy hex nut for structural and mechanical assemblies requiring a 3/4-10 UNC right-hand threaded heavy hex profile.
Installation is typically performed by ironworkers, millwrights, pipefitters, or maintenance technicians using standard open-end, box-end, or impact wrenches sized for 1-1/4 inch hex. Fastener assemblies should comply with applicable structural codes such as AISC, ASTM, or applicable building codes for the jurisdiction. De-energize or lock out any equipment before servicing fasteners on mechanical systems. Do not mix galvanized and non-galvanized hardware in the same assembly without verifying galvanic compatibility.
