The VALUE COLLECTION HNFI2175-005BX is a heavy-duty hex nut sized at 1-3/4-12 (1-3/4 inch diameter, 12 threads per inch) in a UN thread standard. Made from Grade 2 Grade A steel with a bright uncoated finish, this nut is built for structural fastening applications where standard carbon steel performance is acceptable. The right-hand thread profile measures 2.625 inches (2-5/8 inches) across the flats and stands 1.5 inches tall. Plumbers, HVAC technicians, electricians, and general contractors use fasteners like this when assembling equipment frames, pipe supports, duct hangers, and mechanical enclosures.
This hex nut is suited for general industrial and trade fastening tasks in both residential and commercial settings. It installs on any 1-3/4-12 UN threaded bolt or stud. Common applications include equipment mounting structures, support frames, and mechanical assemblies where a large-diameter, fine-thread fastener is required. The uncoated finish is appropriate for interior or protected environments where corrosion resistance is not a primary concern. This item is sold in a minimum order quantity of 5 units.
Designed for use with any 1-3/4-12 UN threaded bolt or stud requiring a Grade 2 steel hex nut with a 2-5/8 inch across-flats dimension.
Install using a properly sized hex socket or open-end wrench matched to the 2-5/8 inch across-flats dimension. Ensure the mating bolt or stud is clean, free of burrs, and matches the 1-3/4-12 UN thread specification before assembly. Torque to the fastener manufacturer or engineer-of-record specification for Grade 2 hardware. The uncoated finish offers no corrosion protection, so avoid use in wet, outdoor, or chemically exposed environments without additional protective measures.
