Value Collection MSC-02216190 Heavy Hex Nut 1-1/8-7 Unc

Product Description

The VALUE COLLECTION MSC-02216190 is a heavy hex nut threaded to the 1-1/8-7 UNC standard, manufactured from steel with a galvanized finish for corrosion resistance. It measures 1-13/16 inches across the flats and stands 1-7/64 inches high, conforming to the larger across-flats and greater thickness dimensions that define the heavy hex series versus standard hex. The right-hand thread direction follows conventional fastener convention. At 0.62 pounds per unit, this nut is suited for high-load bolted connections in structural, mechanical, and industrial applications. Installation requires a wrench sized to the 1-13/16-inch flat dimension.

Heavy hex nuts at this thread size are commonly used in structural steel connections, heavy equipment assemblies, pipe flanges, and industrial machinery where additional bearing surface and greater nut thickness are required to handle elevated clamping loads. The UNC thread form is standard in inch-based mechanical and structural assemblies across construction, manufacturing, and maintenance trades. The galvanized finish provides a baseline level of corrosion protection suitable for outdoor or moderately corrosive environments.

Key Features

• 1-1/8-7 UNC thread specification for inch-standard bolted assemblies
• Heavy hex profile: 1-13/16 inches across flats, 1-7/64 inches high
• Steel construction provides high tensile strength for load-bearing connections
• Galvanized finish for corrosion resistance in exposed or outdoor installations
• Right-hand thread direction — standard for conventional fastener applications

Compatibility

Designed as a heavy hex nut replacement or new-installation fastener for 1-1/8-7 UNC threaded bolts and studs in structural, industrial, and mechanical assemblies requiring the heavy hex dimensional standard.

Installation Notes

Installation is performed by qualified millwrights, ironworkers, pipefitters, or maintenance technicians working with inch-standard fastener systems. Confirm bolt and nut thread class compatibility before assembly. Use a calibrated torque wrench sized to a 1-13/16-inch drive to achieve specified clamp load per applicable structural or equipment standards. Follow AISC, ASME, or equipment-manufacturer torque specifications as appropriate for the application.
