Value Collection MSC-67470922 Hex Nut 1-1/4-7 Grade 8

Product Description

The VALUE COLLECTION MSC-67470922 is a 1-1/4-7 hex nut manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 steel provides high tensile strength suitable for demanding structural and mechanical fastening applications. The zinc yellow dichromate coating adds corrosion resistance and is visually identifiable by its gold-yellow appearance. This nut follows Unified National Coarse (UNC) thread standards with a right-hand thread direction. It measures 1-7/8 inches across the flats and 1-1/16 inches in height. Typically installed by millwrights, maintenance technicians, and structural assembly crews working with heavy-duty bolted connections.

This hex nut is suited for high-load bolted assemblies in industrial, construction, and mechanical maintenance environments. The 1-1/4-7 UNC thread size is commonly found in structural steel connections, heavy equipment mounting, and machinery framing. The Grade 8 rating makes it appropriate for applications requiring elevated proof load and tensile strength where standard or lower-grade hardware would be insufficient. The zinc yellow dichromate finish provides a degree of protection against oxidation in moderately exposed environments.

Key Features

• Grade 8 steel construction for high tensile and proof load capacity
• 1-1/4-7 UNC right-hand thread for standard heavy-duty fastener compatibility
• Zinc yellow dichromate finish provides corrosion resistance and easy visual identification
• 1-7/8 inches across flats for use with standard heavy hex wrench or socket tooling
• 1-1/16 inches height for full thread engagement on matching Grade 8 bolt assemblies

Compatibility

Designed as a standard UNC hex nut for use with 1-1/4-7 Grade 8 bolts and threaded rod in heavy-duty structural and mechanical fastening applications.

Installation Notes

Installation should be performed by qualified mechanical, structural, or maintenance personnel familiar with fastener torque requirements for Grade 8 hardware. Always ensure the mating bolt is also Grade 8 and free of thread damage before assembly. De-energize or lock out any equipment before servicing fastened assemblies on powered machinery. Use a properly sized hex socket or open-end wrench rated for the applied torque to avoid fastener damage.
