The VALUE COLLECTION 99784 is a 1/2-13 UNC steel hex nut designed for right-hand threaded fastener applications. This standard hex nut features a 3/4-inch across-flats dimension and stands 7/16 inches high, making it compatible with common 1/2-inch bolts and threaded rod in mechanical, structural, and plumbing assembly work. Constructed from steel with an uncoated finish, it delivers solid clamping performance in general-purpose installations. Licensed tradespeople and maintenance technicians working in HVAC, plumbing, and electrical panel assembly regularly use hardware of this type to secure equipment, brackets, and structural components.
This hex nut is suited for residential and light commercial applications where a standard UNC right-hand thread pattern is required. Typical use cases include mechanical equipment mounting, pipe bracket fastening, and structural assembly work. The 1/2-13 UNC thread size is one of the most common coarse-thread specifications in North American trade work, making this nut a practical stock item for service vans, job-site bins, and shop inventory.
Designed as a general-purpose replacement or stock hex nut for any assembly using 1/2-13 UNC right-hand threaded bolts, studs, or threaded rod.
Install using a 3/4-inch wrench or socket driver. Power down or depressurize any system before fastening or loosening hardware on live equipment. Torque to the specification required by the equipment manufacturer or applicable structural standard. Inspect threads on mating bolts or studs before installation to ensure clean engagement.
