Value Collection MSC-87921490 Hex Nut 1-8 Unc Grade 2

Product Description

The VALUE COLLECTION MSC-87921490 is a 1-8 UNC hex nut manufactured from Grade 2 steel with a zinc-plated finish. It features a right-hand thread direction and is sized at 1.625 inches across the flats, making it a standard heavy fastener suited for general-purpose bolted assemblies. The zinc plating provides a baseline level of corrosion resistance for indoor and mild-environment applications. This nut is a workhorse fastener used across mechanical, structural, and utility installations by plumbers, pipefitters, HVAC technicians, electricians, and general contractors wherever a 1-inch diameter threaded connection is required.

This hex nut is suited for residential and commercial applications involving 1-8 UNC threaded rod, bolts, or studs. Typical use cases include pipe hanger assemblies, equipment mounting, structural bracketing, and general mechanical fastening. The Grade 2 designation indicates a standard-strength carbon steel fastener appropriate for non-critical structural and utility connections. Zinc plating makes it a practical choice for dry or lightly humid environments where bare steel would be less suitable.

Installation Notes

Installation is performed with a standard open-end, box-end, or socket wrench sized for 1-5/8 inches across flats. De-energize, depressurize, or shut down any system before servicing fastened connections. Do not exceed the torque capacity appropriate for Grade 2 steel fasteners as defined by applicable mechanical standards. Inspect threads on both the nut and mating fastener for damage or contamination before assembly.
