Value Collection HNIX175-001BX Hex Nut 1-3/4-5 Unc

Product Description

The VALUE COLLECTION HNIX175-001BX is a heavy-duty hex nut sized 1-3/4-5 UNC, manufactured from 18-8 stainless steel with a bright, uncoated finish. It features a right-hand thread pattern and measures 2.625 inches across the flats with a height of 1.5 inches. At 0.59 pounds, this nut is suited for structural fastening applications where corrosion resistance is required. Plumbers, pipefitters, HVAC mechanics, and general trade contractors reach for 18-8 stainless hardware when working in wet, outdoor, or chemically active environments where carbon steel fasteners would degrade over time.

This hex nut is appropriate for large-diameter bolted connections in commercial and industrial settings, including equipment mounting, pipe flange assembly, structural steel work, and mechanical systems that see moisture or mild chemical exposure. The UNC thread standard makes it compatible with the widest range of standard American fastener systems. It is sold individually, making it practical for single-bolt repairs or low-quantity jobs where buying a full box is unnecessary.

Key Features

• Sold as a single unit, no minimum bulk purchase required

Compatibility

Designed for use with 1-3/4-5 UNC threaded bolts and studs conforming to standard American thread specifications. Does not meet military specifications.

Installation Notes

A licensed mechanic, pipefitter, or qualified trade professional should install hardware of this size using properly rated hand or impact tools. Always de-energize, depressurize, or shut off the associated system before tightening or replacing fasteners on live equipment. Use calibrated torque equipment appropriate for the fastener size and the joint material. Avoid mixing stainless fasteners with dissimilar metals in submerged or highly conductive environments without accounting for galvanic corrosion potential.
