Value Collection 250291 Coupling Nut 5/8-11 Unc Galvanized Steel

Product Description

The VALUE COLLECTION 250291 is a standard coupling nut used to join or extend threaded rod, bolts, or studs with a 5/8-11 UNC thread profile. Machined from steel with a galvanized finish for corrosion resistance, this hex coupling nut measures 2.125 inches overall length and 13/16 inches across the flats. It carries a right-hand thread direction and meets Grade 2 material specifications. Licensed plumbers, electricians, HVAC technicians, and general contractors reach for coupling nuts like this when connecting threaded rod for pipe hangers, equipment mounting, and structural fastening applications.

This coupling nut is suited for residential and commercial installation work where 5/8-11 UNC threaded rod or fasteners are used. Common applications include pipe hanger assemblies, all-thread rod extensions, and mechanical equipment supports. The galvanized finish makes it appropriate for use in moderately humid or corrosive environments where bare steel would be vulnerable to rust. The ISO 9001:2000 certified manufacturing process provides consistent dimensional accuracy across the part.
