Value Collection 32272 Hex Jam Nut 5/16-18 Unc Steel 50-pack

Product Description

The VALUE COLLECTION 32272 is a 5/16-18 UNC hex jam nut designed for use in mechanical assemblies where a low-profile locking nut is required. Manufactured from steel with a zinc-plated finish for basic corrosion resistance, this nut features right-hand threading conforming to Unified National Coarse (UNC) standards. Measuring 1/2 inch across the flats and 3/16 inch in height, the jam nut profile allows it to be tightened against a standard hex nut to lock a fastener assembly in place. This SKU ships in a pack of 50 units, making it practical for shop stock and field service kits.

Hex jam nuts in this thread size see broad use across general mechanical, HVAC equipment, plumbing fixture, and electrical enclosure assemblies. The 5/16-18 UNC thread is one of the most common coarse-thread fastener sizes found in light to medium-duty equipment, structural brackets, and control panel hardware. Installers in residential and light commercial service trades regularly stock this size for mounting components, securing threaded rod assemblies, and locking adjustment mechanisms in place. The zinc-plated finish provides suitable service in dry or mildly humid indoor environments.

Key Features

• 5/16-18 UNC right-hand thread for broad compatibility with standard coarse-thread fastener systems
• Low-profile jam nut at 3/16 inch height locks against a mating nut to prevent loosening under vibration
• 1/2 inch across flats for use with standard 1/2-inch open-end, box, or socket wrenches
• Steel construction with zinc-plated finish for basic corrosion resistance in dry indoor applications
• Pack of 50 units suits shop inventory, service van stock, and repetitive assembly tasks

Compatibility

Designed as a standard 5/16-18 UNC hex jam nut suitable for use with any male-threaded fastener or rod conforming to the Unified National Coarse thread standard at that diameter and pitch.

Installation Notes

Hex jam nuts are installed by a wide range of trades including HVAC technicians, plumbers, and electricians as part of equipment mounting and fastener locking tasks. Thread the jam nut onto the fastener first, then install the primary nut and tighten the two against each other using two wrenches. Do not over-torque; jam nuts are thin-profile and may deform if excessive force is applied. Ensure mating threads are clean and free of debris before installation.
