Value Collection FHN-1187-GD8 Hex Nut 1-1/8-7 Unc

Product Description

The VALUE COLLECTION FHN-1187-GD8 is a Grade 8 steel hex nut threaded to the 1-1/8-7 UNC standard with a right-hand thread direction. It measures 1-11/16 inches across the flats and 31/32 inches in height. The bright, uncoated finish leaves the steel surface bare, making it suitable for applications where a secondary coating or plating will be applied, or where bare steel is acceptable. This nut is used in heavy-duty fastening assemblies across mechanical, structural, and industrial maintenance work. Trades including millwrights, pipefitters, and industrial maintenance technicians reach for Grade 8 hardware when joint loading demands a higher-strength fastener than standard Grade 2 or Grade 5 hex nuts provide.

This hex nut is suited for use in structural bolted connections, heavy equipment assembly, and mechanical systems that require high-strength UNC fasteners. The 1-1/8-7 thread size is common in large-diameter bolted joints found in industrial machinery frames, heavy fabrications, and utility infrastructure applications. Its right-hand thread mates with standard 1-1/8-7 UNC bolts and studs without modification.

Key Features

• Grade 8 steel construction for high tensile and proof-load performance
• 1-1/8-7 UNC right-hand thread for compatibility with standard UNC fastener systems
• 1-11/16 inches across flats for use with standard hex wrenches and sockets
• 31/32 inches height provides full thread engagement depth
• Bright, uncoated finish — accepts field-applied coatings or platings
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed for use with 1-1/8-7 UNC right-hand threaded bolts and studs in commercial and industrial fastening applications.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a standard hex wrench or impact socket sized for 1-11/16 inches across the flats. Always verify that the mating bolt or stud matches the 1-1/8-7 UNC thread specification before assembly. Follow applicable torque guidelines from the joint design or equipment manufacturer for Grade 8 hardware. Inspect threads for damage or contamination prior to assembly to ensure proper seating.
