Value Collection HNI2200-005BX Hex Nut 2-4-1/2 Grade 2

Product Description

The VALUE COLLECTION HNI2200-005BX is a heavy hex nut with a 2-4-1/2 inch thread size, manufactured from Grade 2, Grade A steel with a bright uncoated finish. It features a right-hand Unified National Coarse (UNC) thread standard and measures 3 inches across the flats with a height of 1-23/32 inches. Weighing 2.21 pounds, this nut is built for general-purpose structural and mechanical fastening applications where a large-diameter, high-strength threaded connection is required. Licensed tradespeople and industrial maintenance technicians rely on this size for heavy equipment assembly, pipe flanges, and structural steel work.

This hex nut is suited for residential, commercial, and industrial applications that require a 2-4-1/2 UNC threaded fastener. Typical use cases include structural steel connections, heavy machinery assembly, flange bolting, and large-diameter piping systems. The uncoated bright finish makes it compatible with environments where additional coating or paint will be applied on-site, or where bare steel is acceptable per the application specification.

Key Features

• Thread size 2-4-1/2 inch UNC for large-diameter fastening applications
• Grade 2, Grade A steel construction for general-purpose mechanical strength
• Right-hand thread direction per UNC standard
• 3 inches across flats for use with standard heavy-duty wrenches and sockets
• Bright uncoated finish suitable for further coating or bare-steel installations
• Height of 1-23/32 inches provides full thread engagement on compatible bolts

Compatibility

Designed for use with 2-4-1/2 UNC threaded bolts and studs in general-purpose structural, mechanical, and industrial fastening applications.

Installation Notes

Installation of large-diameter fasteners of this type is typically performed by millwrights, ironworkers, pipefitters, or maintenance mechanics using heavy-duty torque wrenches or impact tools rated for the fastener size. Always ensure the mating bolt or stud is the same thread standard and size before assembly. De-energize and lock out any equipment before working on mechanical connections. Follow applicable structural or mechanical codes for torque requirements specific to the assembly.
