Value Collection JNFI2137-010BX Hex Nut 1-3/8-12 Unf

Product Description

The VALUE COLLECTION JNFI2137-010BX is a 1-3/8-12 UNF hex nut manufactured from Grade 2 steel with a bright, uncoated finish. It features a right-hand thread pattern and measures 2.0625 inches across the flats with a height of 25/32 inches. This nut is a standard fastener used in mechanical assemblies, structural connections, and equipment fabrication where a coarse-to-fine unified thread is required. It is installed by mechanics, pipefitters, millwrights, and general tradespeople working on heavy equipment, frames, or threaded rod applications. The Grade 2 designation indicates a low-carbon steel specification suitable for general-purpose fastening where high-strength grades are not required.

This hex nut is suited for residential, commercial, and light industrial applications involving 1-3/8-12 UNF threaded bolts or studs. Typical use cases include machinery assembly, structural steel connections, HVAC equipment mounting, and general maintenance and repair work. Its uncoated bright finish is appropriate for indoor or protected installations where corrosion resistance is not a primary concern. The standard hex profile accepts common hand and power tools.

Key Features

• 1-3/8-12 UNF thread size for fine-thread applications

Compatibility

Designed as an OEM-style replacement or standard-use hex nut for any 1-3/8-12 UNF threaded bolt or stud requiring a Grade 2 steel fastener with a right-hand thread.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance tradespeople using a standard combination wrench or socket sized to 2.0625 inches across the flats. Ensure the mating bolt or stud is also 1-3/8-12 UNF and free of debris or damage before threading. Do not exceed the torque capacity of Grade 2 hardware; consult applicable fastener torque tables for the assembly specification. Follow all applicable mechanical and structural codes for the installation environment.
