The VALUE COLLECTION NHH056C2ZPKG is a 9/16-12 UNC hex nut manufactured from Grade 2 steel with a zinc-plated finish. It features a right-hand thread pattern and measures 15/16 inches (0.9375 inches) across the flats with a height of 0.5469 inches. The zinc plating provides basic corrosion resistance for general-purpose fastening applications. This nut is a standard hardware component used by electricians, plumbers, HVAC technicians, and general contractors wherever a 9/16-12 UNC threaded connection is required. It ships in a minimum order quantity of 25 pieces.
This hex nut is suited for light to medium-duty fastening in residential and commercial construction, mechanical assemblies, equipment mounting, and utility installations. Its Grade 2 steel construction makes it appropriate for non-structural and general fastening applications where high tensile strength is not a primary requirement. The zinc finish offers adequate protection in dry or mildly humid indoor environments.
Designed as a standard replacement or stock hex nut for any application requiring a 9/16-12 UNC right-hand threaded nut in Grade 2 steel with a zinc-plated finish.
Install using a 15/16 inch open-end, box, or socket wrench. Ensure mating bolt or threaded rod is also 9/16-12 UNC before assembly. Do not use Grade 2 hardware in high-load structural or safety-critical joints where higher grade fasteners are specified by engineering drawings or applicable codes. Inspect threads for damage before installation and discard any nuts with cross-threading or deformation.
