Value Collection B52001647 Hex Nut Grade 8 Steel Unc

Product Description

The VALUE COLLECTION B52001647 is a Grade 8 steel hex nut with a 2-4-1/2 inch UNC thread size, designed for heavy-duty bolted assemblies where high tensile strength is required. The uncoated bright finish leaves the steel surface bare, making it suitable for applications where coating thickness tolerance matters or where the fastener will be treated or painted in the field. At 3-1/8 inches across the flats and 1-23/32 inches in height, this is a large-format nut intended for substantial structural or mechanical connections. It weighs approximately 0.4 pounds. Licensed trades and industrial maintenance crews use Grade 8 hardware on structural steel, heavy equipment, and high-load mechanical assemblies.

This hex nut is used in commercial and industrial fastening applications where high-strength fasteners are specified. Typical install scenarios include structural steel connections, heavy fabrication, agricultural equipment, and industrial machinery maintenance. The right-hand thread orientation is standard for most bolted connections. It pairs with 2-inch diameter, Grade 8 or equivalent bolts threaded to UNC specification. Sold individually, it is appropriate for low-volume repair work or as a replacement for a single worn or damaged nut in a larger assembly.

Key Features

• Grade 8 steel construction for high tensile and proof load strength in heavy-duty applications
• 2-4-1/2 UNC thread size with right-hand thread direction for standard bolted connections
• 3-1/8 inches across flats for use with standard large-format wrenches and impact tools
• 1-23/32 inches nut height provides full thread engagement depth on large-diameter bolts
• Bright uncoated finish allows field coating or precise tolerance fitment without added plating thickness
• Single-unit packaging suitable for replacement or low-volume repair applications

Compatibility

Designed for use with 2-inch diameter, Grade 8 UNC bolts and threaded rod in heavy structural and industrial fastening applications. No specific OEM or model compatibility is stated by the manufacturer.

Installation Notes

Installation of large-format Grade 8 fasteners is typically performed by industrial maintenance technicians, ironworkers, or millwrights. Always de-energize or relieve pressure from any system before loosening or replacing structural fasteners. Use a properly rated wrench or impact driver sized for 3-1/8 inches across the flats. Structural bolting applications may be governed by AISC or applicable building code requirements — consult project specifications before installation.
