Product Description

The VALUE COLLECTION MSC-87921482 is a 7/8-9 UNC hex nut made from Grade 2 steel with a zinc-plated finish. It features a right-hand thread pattern and measures 1.4375 inches across the flats, making it a standard-duty fastener suited for general mechanical and structural assembly work. The zinc plating provides basic corrosion resistance for indoor and sheltered outdoor applications. At 0.25 pounds per unit, this nut is a workhorse component used across a wide range of trade and industrial assembly tasks where a reliable, cost-effective hex nut is needed.

This hex nut is appropriate for general-purpose fastening in mechanical, structural, and light industrial applications. It is commonly used in HVAC equipment mounting, plumbing fixture support, electrical panel framing, and general equipment assembly. The 7/8-9 UNC thread size is a widely used coarse-thread standard, making this nut compatible with a broad range of threaded rod, bolts, and studs found in trade environments. It is installed by HVAC technicians, plumbers, electricians, and maintenance professionals as part of routine equipment installation and repair.
