Value Collection R50000027 Hex Jam Lock Nut 1/4-28

Product Description

The VALUE COLLECTION R50000027 is a 1/4-28 UNF hex jam lock nut with a nylon insert locking mechanism. It is manufactured from Grade 2 steel with a zinc finish for corrosion resistance. The low-profile jam nut profile measures 7/32 inches in height and 7/16 inches across the flats, making it suited for applications where thread engagement depth is limited. The nylon insert creates prevailing torque that resists loosening under vibration without requiring thread-locking compounds. Electricians, plumbers, HVAC technicians, and mechanical contractors use this style of fastener in panel assemblies, equipment mounts, and mechanical linkages.

This hex jam lock nut is used in light-duty threaded fastening applications across residential and commercial construction and mechanical service. The 1/4-28 UNF thread specification suits fine-thread applications requiring precise torque control and vibration resistance. It is appropriate for use in electrical enclosures, HVAC equipment panels, plumbing fixture assemblies, and general mechanical fabrication where a low-profile locking nut is needed on a 1/4-inch fine-thread fastener.

Key Features

• Nylon insert provides prevailing-torque locking without thread-locking adhesives
• Low-profile jam nut height of 7/32 inches for space-constrained installations
• 1/4-28 UNF right-hand thread for fine-thread applications
• Grade 2 steel construction for light-duty fastening requirements
• Zinc finish provides basic corrosion resistance in dry or mildly humid environments
• Conforms to inch system of measurement and UNF fastener standards

Compatibility

Designed as a standard UNF jam lock nut compatible with any 1/4-28 right-hand threaded stud, bolt, or rod used in light-duty mechanical, electrical, or HVAC assembly applications.

Installation Notes

Installation is performed with a standard 7/16-inch open-end or combination wrench. Ensure the mating thread is clean and free of debris before seating the nut. The nylon insert is a single-use locking feature and may lose prevailing torque if removed and reinstalled repeatedly. Follow applicable mechanical and electrical codes when using fasteners in code-governed assemblies.
