Value Collection FHN-1126-GD8 Hex Nut 1-1/2-6 Grade 8

Product Description

The VALUE COLLECTION FHN-1126-GD8 is a heavy-duty hex nut machined from Grade 8 steel with a black oxide finish. It is designed for high-strength fastening applications where standard hardware grades are insufficient. The 1-1/2-6 UNC thread size and right-hand thread direction make it compatible with standard coarse-thread fastener systems. At 2-1/4 inches across the flats and 1-9/32 inches tall, this nut is built for structural, mechanical, and industrial bolted connections. Maintenance technicians, millwrights, and contractors working on heavy equipment, machinery mounts, or structural assemblies are the typical end users.

This hex nut is suited for use in demanding commercial and industrial environments where high clamping force and resistance to loosening are required. Its Grade 8 rating indicates a minimum tensile strength well above that of standard SAE grades, making it appropriate for critical bolted joints in mechanical equipment, structural steel connections, and heavy-duty mounting applications. The black oxide finish provides a degree of corrosion resistance in dry or mildly humid conditions.

Key Features

• Grade 8 steel construction for high-strength fastening requirements
• 1-1/2-6 UNC right-hand thread for compatibility with standard coarse-thread bolt systems
• 2-1/4 inches across flats for use with standard heavy hex tooling
• 1-9/32 inches height provides substantial thread engagement depth
• Black oxide finish offers mild corrosion resistance and a low-reflectance appearance

Compatibility

Designed as a standard UNC coarse-thread hex nut for use with 1-1/2-6 Grade 8 or equivalent threaded fasteners in structural and mechanical applications.

Installation Notes

Installation should be performed by qualified mechanical or structural tradespeople following applicable torque specifications for the bolted joint design. Always ensure the mating bolt or stud is the same thread standard and grade before assembly. Use an appropriate heavy hex wrench or impact socket rated for the fastener size. Inspect threads for damage or contamination before installation to prevent galling or improper seating.
