Value Collection HNIX150-001BX Hex Nut 1-1/2-6 Unc

Product Description

The Value Collection HNIX150-001BX is a heavy-duty hex nut in 1-1/2-6 UNC thread, manufactured from 18-8 stainless steel with a bright, uncoated finish. It features a right-hand thread direction and measures 2.25 inches across the flats with a height of 1-9/32 inches. The 18-8 stainless alloy provides solid corrosion resistance in wet, chemical-exposed, and outdoor environments without surface plating. Plumbers, pipefitters, electricians, and general mechanical contractors use this size for large-diameter fastening applications in both commercial and industrial settings. The part ships individually and weighs 0.42 pounds.

This hex nut is suited for structural, plumbing, mechanical, and industrial assembly work where a 1-1/2-6 UNC coarse-thread fastener and corrosion-resistant material are specified. Typical applications include pipe flange connections, equipment mounting, and utility infrastructure work where stainless fasteners are required by specification or environmental conditions. The uncoated bright finish is appropriate for applications where additional surface treatment is not required or where secondary coating will be applied on site.

Key Features

• 18-8 stainless steel construction for corrosion resistance without a plated coating
• 1-1/2-6 UNC coarse-thread specification for high-load fastening
• Right-hand thread direction per standard UNC convention
• 2.25 inches across flats for use with standard 2-1/4 inch wrenching tools
• Bright, uncoated finish suitable for secondary treatment or direct installation

Compatibility

Designed as a standard UNC hex nut for use with any 1-1/2-6 UNC-threaded bolt, stud, or rod where an 18-8 stainless steel nut is specified.

Installation Notes

Installation is performed by qualified mechanics, pipefitters, or plumbers using the appropriate 2-1/4 inch open-end, box, or socket wrench. Always confirm thread engagement and alignment before applying final torque. Stainless steel fasteners are susceptible to galling — apply an anti-seize compound to threads prior to assembly to reduce this risk. De-energize and depressurize any system before replacing or installing hardware in live mechanical assemblies.
