Value Collection NHJ125CPKG Hex Nut 1-1/4-7 Unc Grade 2

Product Description

The VALUE COLLECTION NHJ125CPKG is a 1-1/4-7 UNC hex nut manufactured from Grade 2 steel with a bright, uncoated finish. It carries a right-hand thread and conforms to ASME B1.1 and ASME B18.2.2 standards. The nut measures 2 inches across flats and 23/32 inches in height, with a Thread Fit Class of 2B. Hardness is rated between 68 HRB and 32 HRC. This fastener is suited for general-purpose mechanical and structural assembly work where corrosion resistance is not a primary requirement and standard carbon steel performance is acceptable.

This hex nut is intended for use in light to medium-duty bolted assemblies requiring a 1-1/4-7 UNC thread engagement. Typical applications include structural framing, equipment mounting, pipe flange assembly, and general mechanical fabrication. It is commonly installed by pipefitters, millwrights, ironworkers, and general maintenance technicians across commercial and industrial settings. The uncoated finish is appropriate for interior or dry environments, or where a secondary coating will be applied after installation.

Compatibility

Designed as an OEM-style replacement or standard-use hex nut for bolted assemblies requiring a 1-1/4-7 UNC thread form and Grade 2 steel construction per ASME B18.2.2.

Installation Notes

Installation requires a standard 2-inch open-end, box-end, or socket wrench. Ensure the mating bolt thread class and grade are compatible before installation. Disengage and isolate any mechanical or electrical load on the assembly before removing or replacing fasteners. Do not use impact tools at torque values beyond the rated capacity of Grade 2 hardware, as this grade is not hardened for high-tension structural applications governed by AISC or RCSC specifications.
