Value Collection MSC-02216174 Heavy Hex Nut 7/8-9 Unc

Product Description

The VALUE COLLECTION MSC-02216174 is a heavy hex nut designed for bolted assemblies requiring a larger bearing surface and greater wall thickness than standard hex nuts. Sized at 7/8-9 UNC, this nut features a right-hand thread and a galvanized finish that provides corrosion resistance in exposed or outdoor applications. Measuring 1-7/16 inches across the flats and 55/64 inches in height, it conforms to heavy hex dimensional standards. At 0.3 pounds per unit, it is suited for structural, industrial, and mechanical fastening work where a standard hex nut does not meet load or bearing requirements.

This heavy hex nut is used in structural steel construction, industrial equipment assembly, utility and infrastructure work, and heavy mechanical applications. The 7/8-9 UNC thread size is common in general industrial fastening, structural bolting, and equipment mounting. The galvanized finish makes it appropriate for outdoor installations, bridge work, and environments with moderate moisture exposure. Installation is typically performed by ironworkers, millwrights, pipefitters, or maintenance technicians working with structural steel or heavy equipment.

Key Features

• Heavy hex profile provides larger bearing surface and greater wall thickness versus standard hex nuts
• 7/8-9 UNC right-hand thread for compatibility with standard UNC-threaded fasteners
• Galvanized finish for corrosion resistance in outdoor and moisture-exposed environments
• Steel construction for high strength and durability in structural and industrial applications
• 1-7/16 inches across flats, 55/64 inches high per heavy hex dimensional standards

Compatibility

Designed for use with 7/8-9 UNC threaded bolts and studs in structural and industrial fastening applications. Conforms to heavy hex nut dimensional standards for that thread size.

Installation Notes

Installation should follow applicable structural or mechanical fastening standards, including AISC or ASME guidelines where required. Use the appropriate size wrench or impact socket sized for 1-7/16 inches across the flats. Verify thread engagement and ensure mating bolt threads are clean and undamaged before assembly. Do not use this nut on metric or left-hand threaded fasteners.
