Value Collection 329530BR Jam Nut 1-14 Unf Grade 2 Steel

Product Description

The VALUE COLLECTION 329530BR is a 1-14 UNF jam nut manufactured from Grade 2 steel with a bright, uncoated finish. Jam nuts are thin hex nuts used to lock a standard nut in place or to secure threaded rod, studs, and fastener assemblies where a full-height nut would exceed available thread engagement. This nut measures 1-1/2 inches across flats and 0.5469 inches in height, with a right-hand thread pattern conforming to Unified National Fine (UNF) standards. It is a common hardware component installed by HVAC technicians, plumbers, electricians, pipefitters, and general tradespeople during equipment mounting and mechanical assembly work.

This jam nut is suited for use in mechanical assemblies requiring a fine-thread 1-14 fastener. Typical applications include equipment mounting brackets, threaded rod assemblies, pipe hanger hardware, and structural fastener locknut configurations in residential and light commercial trade work. The UNF thread form provides finer thread pitch and greater resistance to vibration loosening compared to coarse-thread equivalents, making it appropriate for applications subject to moderate vibration.

Key Features

• Jam nut profile at 0.5469 inches height allows use in tight thread-engagement situations
• 1-14 UNF thread standard for fine-pitch fastening applications
• 1-1/2 inches across flats fits standard 1-1/2 inch hex wrench or socket
• Grade 2 steel construction for general-purpose mechanical assemblies
• Bright uncoated finish — suitable for interior and dry-environment use
• Right-hand thread direction per standard UNF convention

Compatibility

Designed for use with any 1-14 UNF threaded rod, stud, or bolt in general-purpose mechanical and trade fastening assemblies. Does not meet military specifications.

Installation Notes

Jam nuts are typically installed by hand and tightened with a standard hex wrench or socket. When used as a locknut, the jam nut is threaded down first and then the primary nut is torqued against it while holding the jam nut in position. Verify thread engagement is sufficient before applying load. Bright uncoated steel is not corrosion-resistant — do not use in direct-moisture or outdoor environments without appropriate corrosion protection.
