Value Collection MSC-67471367 Hex Nut 7/8-9 Unc Grade 5

Product Description

The VALUE COLLECTION MSC-67471367 is a 7/8-9 UNC hex nut manufactured from Grade 5 steel with a zinc-plated finish. It features a right-hand thread direction and measures 1.3125 inches across the flats with a height of 0.75 inches. Weighing approximately 0.2 pounds, this nut is a standard fastener used across a wide range of mechanical, structural, and industrial assembly applications. Installation is performed by maintenance technicians, millwrights, pipefitters, and general tradespeople wherever a reliable threaded connection to a 7/8-9 bolt is required.

This hex nut is suited for general-purpose fastening in residential, commercial, and light industrial settings. The 7/8-9 UNC thread size is common in structural steel fabrication, equipment mounting, piping supports, and mechanical assemblies. The zinc plating provides a baseline level of corrosion resistance for use in dry to mildly humid environments. It does not meet military specifications and is intended for standard commercial-grade applications.

Key Features

• Grade 5 steel construction for dependable tensile strength in standard fastening applications
• Zinc-plated finish for basic corrosion resistance in dry and mildly humid environments
• 7/8-9 UNC right-hand thread for compatibility with standard inch-series threaded fasteners
• 1.3125 inches across flats — accepts standard 1-5/16 inch wrenches or sockets
• 0.75 inch height provides full thread engagement depth on standard bolt lengths
• Does not meet military specifications — rated for commercial-grade service only

Compatibility

Designed as a standard commercial-grade replacement or assembly hex nut for any 7/8-9 UNC threaded bolt or stud application requiring a Grade 5 steel fastener.

Installation Notes

Installation is performed by hand-threading the nut onto a clean, undamaged 7/8-9 UNC threaded fastener, then tightening with a 1-5/16 inch open-end, box, or socket wrench. Always inspect mating threads for damage or contamination before installation. Follow applicable torque specifications from the equipment manufacturer or relevant structural codes for the specific joint being assembled. Do not use this fastener in applications requiring military-specification hardware.
