Value Collection 320335BR Hex Nut 1-3/4-5 Unc Grade 2

Product Description

The VALUE COLLECTION 320335BR is a heavy-duty hex nut threaded to the 1-3/4-5 UNC standard, manufactured from Grade 2 steel with a zinc-plated finish for corrosion resistance. It features a right-hand thread direction and measures 2.75 inches across the flats, making it suited for large-diameter fastener assemblies. At 1-23/32 inches in height, this nut provides substantial thread engagement for structural and mechanical connections. Licensed tradespeople and maintenance mechanics install this fastener in heavy equipment, structural steel, industrial machinery, and large-diameter piping systems where standard UNC coarse-thread hardware is required.

This hex nut is used in commercial and industrial applications requiring a 1-3/4-5 UNC coarse-thread fastener. Typical scenarios include structural steel assembly, heavy mechanical equipment maintenance, and large-bore piping flange connections. The zinc-plated finish provides a baseline level of corrosion protection suitable for indoor and mildly exposed environments. Mechanics, millwrights, pipefitters, and maintenance technicians working with oversized UNC fastener systems are the primary installers of this hardware.

Key Features

• 1-3/4-5 UNC right-hand thread for compatibility with standard coarse-thread fastener systems
• Grade 2 steel construction provides reliable strength for general industrial and structural use
• Zinc-plated finish delivers corrosion resistance in mildly exposed environments
• 2.75 inches across flats accommodates standard oversized wrench and socket tooling
• 1-23/32 inch height provides substantial thread engagement depth

Compatibility

Designed for use with 1-3/4-5 UNC coarse-thread bolts and threaded rod in general industrial, structural, and mechanical fastening applications.

Installation Notes

Installation requires a properly sized wrench or socket matching the 2.75-inch across-flats dimension. Always ensure mating bolt or threaded rod is the same UNC thread standard and grade before assembly. Follow applicable torque guidelines from the relevant mechanical or structural code for Grade 2 steel fasteners. Inspect threads on both the nut and mating fastener for damage or debris before installation.
