Value Collection HNI2162-005BX Hex Nut 1-5/8-5-1/2 Unc

Product Description

The VALUE COLLECTION HNI2162-005BX is a heavy hex nut threaded to 1-5/8-5-1/2 UNC (Unified National Coarse) specification, manufactured from Grade 2, Grade A steel with a bright uncoated finish. It carries a right-hand thread direction and measures 2-7/16 inches across the flats and 1-25/64 inches in height. Weighing approximately 1.15 pounds per unit, this nut is sized for large-diameter fastener applications common in structural, industrial, and mechanical assemblies. Installation is performed by maintenance mechanics, millwrights, pipefitters, and general industrial tradespeople working with large-bore threaded rod or bolting systems.

This hex nut is suited for heavy-duty bolted connections in industrial equipment, structural steel framing, large piping supports, and machinery mounting applications. The uncoated bright finish is appropriate for interior use or applications where a secondary coating or galvanizing will be applied in the field. The UNC thread standard ensures broad compatibility with standard inch-series threaded fasteners at this diameter.

Key Features

• 1-5/8-5-1/2 UNC thread specification for large-diameter inch-series bolting
• Grade 2, Grade A steel construction meets standard commercial fastener strength requirements
• Right-hand thread direction, standard for most industrial and structural applications
• Bright uncoated finish compatible with field-applied coatings or galvanizing
• 2-7/16 inches across flats for use with standard heavy hex wrench and socket sizing
• 1-25/64 inches nut height provides full thread engagement depth for this diameter

Compatibility

Designed for use with 1-5/8-inch diameter UNC-threaded bolts, rods, and studs in standard inch-series fastener assemblies.

Installation Notes

Installation is typically performed by mechanics or ironworkers using a heavy hex socket or open-end wrench sized to 2-7/16 inches across the flats. Verify mating bolt or threaded rod is the same thread standard (UNC) and grade before assembly. De-energize or depressurize any system before disassembling bolted connections. Follow applicable torque requirements per structural or mechanical engineering specifications for the assembly.
