The VALUE COLLECTION 250242 is a standard coupling nut machined from 18-8 stainless steel, designed to join two externally threaded fasteners along a common axis. With a 3/4-10 UNC thread size and an overall length of 2.25 inches, this nut provides extended thread engagement compared to a standard hex nut. The 1-inch width across flats allows for engagement with a standard combination or open-end wrench. This fastener is suited for mechanical assembly, structural connections, and threaded rod extensions in corrosive or outdoor environments where stainless steel is specified. Installers working in plumbing, HVAC equipment mounting, and industrial assemblies commonly use coupling nuts of this type.
This coupling nut is a fit for applications requiring right-hand threaded rod coupling, stud extension, or turnbuckle-style length adjustment. The 18-8 stainless steel construction offers good corrosion resistance in wet, humid, and mildly acidic environments, making it appropriate for mechanical rooms, rooftop equipment mounts, pool equipment enclosures, and similar trade installations. The UNC thread standard ensures broad compatibility with inch-series threaded rod and fasteners commonly found in commercial and residential construction.
Designed for use with 3/4-10 UNC right-hand threaded rod and externally threaded fasteners conforming to the UNC inch-series thread standard.
Installation is typically performed by millwrights, pipefitters, plumbers, or general mechanical contractors using an open-end or combination wrench sized to 1 inch across flats. Ensure mating threads are clean and free of debris before assembly to prevent galling, which is a known risk with stainless steel fasteners — applying an anti-seize compound is standard practice. Torque to values specified by the project engineer or applicable fastener specification for the thread size and material grade. Verify thread direction and engagement length before final tightening.
