Product Description

The VALUE COLLECTION R52001105 is a heavy hex nut sized 1-1/2-6, manufactured from SAE J995 Grade 2 steel with a bright, uncoated finish. It features a right-hand UN thread and is dimensioned to ANSI/ASME B18.2.2 standards. With a width across flats of 2.25 inches and a height of 1.2813 inches, this nut is suited for structural and mechanical fastening applications requiring a standard-grade steel fastener. It is installed by plumbers, pipefitters, millwrights, and general maintenance trades using standard hex wrenches or impact tooling sized for a 2.25-inch flat span.

This hex nut is used in industrial, commercial, and residential applications wherever a 1-1/2-6 UNC threaded fastener connection is required. Typical uses include pipe flange assemblies, structural steel connections, equipment mounting, and general mechanical fastening. The Grade 2 classification indicates a mid-range carbon steel construction appropriate for non-critical load-bearing joints that do not require high-strength or military-specification hardware.
