Value Collection JNFI2125-005BX Hex Nut 1-1/4-12 Unf

Product Description

The VALUE COLLECTION JNFI2125-005BX is a 1-1/4-12 UNF hex nut machined from Grade 2 steel with a bright uncoated finish. It uses a right-hand thread pattern and measures 1-7/8 inches across the flats with a height of 23/32 inches. This nut weighs approximately 0.33 pounds and is suited for general-purpose fastening applications where a fine-thread nut in the 1-1/4-inch diameter class is required. Plumbers, pipefitters, HVAC technicians, and general mechanical tradespeople use this style of nut in structural assemblies, equipment mounting, and mechanical joint work.

This hex nut fits applications requiring a 1-1/4-12 UNF fine-thread engagement. Its Grade 2 steel construction makes it appropriate for low- to medium-strength fastening in non-corrosive environments. Typical installations include mechanical equipment mounting, HVAC equipment frames, plumbing equipment supports, and general steel-to-steel assembly work where a standard uncoated carbon steel nut is acceptable.

Key Features

• 1-1/4-12 UNF right-hand thread for fine-thread engagement
• Grade 2 steel construction for general-purpose fastening
• Bright uncoated finish suitable for dry or low-corrosion environments
• 1-7/8 inches across flats for use with standard hex wrenches and sockets
• 23/32 inch height provides full thread engagement depth

Compatibility

Designed as a standard 1-1/4-12 UNF hex nut compatible with any Grade 2 or equivalent threaded rod, bolt, or stud using the same thread specification in general mechanical and trade applications.

Installation Notes

This nut is installed by licensed tradespeople and qualified mechanical technicians using standard hex wrenches or sockets sized for 1-7/8-inch across-flats. Ensure the mating thread is also a 1-1/4-12 UNF right-hand thread before installation. Do not use impact tools beyond the torque appropriate for Grade 2 hardware, and inspect threads for damage or contamination before assembly. Grade 2 steel is not rated for high-temperature or high-corrosion environments without additional protective measures.
