The VALUE COLLECTION MSC-52593415 is a 1/2-20 UNF steel hex nut intended for standard right-hand threaded fastening applications. It measures 0.75 inches across the flats and stands 0.4375 inches high, making it a compact, full-pattern hex nut suited to close-clearance assemblies. The nut is uncoated steel and carries no special military specification designation. It is installed by mechanics, maintenance technicians, and trade professionals wherever a 1/2-20 UNF threaded fastener requires a mating nut for clamping or retention.
This hex nut fits within general mechanical and industrial assembly work, including HVAC equipment mounting, plumbing fixture bracketing, and electrical enclosure hardware. It is appropriate for any application requiring a right-hand, fine-thread, 1/2-20 UNF nut on a steel fastener. The uncoated finish is suited to dry or lightly lubricated environments where additional corrosion protection is applied separately or is not required by the application.
Designed as an OEM-style replacement or general-service hex nut for any assembly using 1/2-20 UNF right-hand threaded fasteners in steel construction.
Install using a 3/4-inch open-end wrench, combination wrench, or socket driver. Verify that the mating bolt or stud carries a matching 1/2-20 UNF right-hand thread before installation. Always de-energize and isolate any equipment before performing fastener service near electrical or pressurized components. Apply thread lubricant or locking compound as required by the assembly specification.
