Value Collection 3396 Hex Jam Nut 1/2-13 Unc Stainless Steel

Product Description

The VALUE COLLECTION 3396 is a 1/2-13 UNC hex jam nut manufactured from stainless steel with a right-hand thread direction. Jam nuts are thin-profile nuts used to lock a standard nut in place or to secure threaded rod, stud, or bolt assemblies against loosening under vibration or torque. At 3/4 inch across the flats and 5/16 inch high, this nut fits standard 1/2-inch UNC threaded fastener applications. The uncoated stainless steel construction provides corrosion resistance suitable for wet, outdoor, or chemically exposed environments. Plumbers, pipefitters, electricians, and mechanical contractors commonly use hex jam nuts in equipment mounting, conduit support, and threaded rod assemblies.

This hex jam nut is suited for use in residential and commercial mechanical installations where a thin locking nut is required on 1/2-13 UNC threaded fasteners. Typical applications include equipment support rod assemblies, unistrut and channel nut locking, conduit hanger rods, and general mechanical fastening where a second nut is needed to prevent back-out. The stainless steel material makes it appropriate for damp locations, rooftop equipment, and other corrosion-prone environments.

Key Features

• 1/2-13 UNC right-hand thread for compatibility with standard inch-series threaded fasteners
• Hex jam nut profile at 5/16 inch high allows use as a locking nut against a primary nut
• 3/4 inch across flats for use with standard 3/4-inch open-end or box wrenches
• Stainless steel construction provides corrosion resistance in wet and outdoor environments
• Uncoated finish — no plating to crack, chip, or corrode in harsh conditions

Compatibility

Designed as a standard hex jam nut for use with 1/2-13 UNC threaded rod, bolts, and studs in mechanical, plumbing, and electrical support applications.

Installation Notes

Installation is performed by threading the jam nut onto a 1/2-13 UNC threaded fastener and tightening against an adjacent nut using two wrenches to lock the assembly. Ensure the mating threads are clean and free of debris before installation. Do not over-torque, as stainless steel fasteners are susceptible to galling — use appropriate anti-seize compound where galling is a concern. Follow applicable mechanical or structural codes for the specific installation type.
