The VALUE COLLECTION 5905 is a 1/4-28 UNF stainless steel hex jam nut used for locking a standard hex nut in place or fastening components where a low-profile nut is required. It features a right-hand thread pattern and measures 7/16 inches across the flats with a height of 5/32 inches. Manufactured from stainless steel with no coating applied, this nut resists corrosion in wet, chemical-exposure, or outdoor environments. It is sold individually but carries a minimum order quantity of 100 pieces, making it appropriate for stocking or project-quantity procurement. HVAC, plumbing, and general mechanical trades use jam nuts like this one in control panel assemblies, threaded rod installations, and equipment mounting applications.
This hex jam nut is suited for light mechanical assemblies requiring a 1/4-28 UNF fine-thread fastener with corrosion resistance. Its low-profile design allows it to seat tightly against a mating nut or surface, preventing loosening under vibration. Typical applications include equipment brackets, instrument panel hardware, and threaded rod locknut configurations in residential and light commercial trade work. The uncoated stainless steel finish makes it compatible with environments where zinc or plated fasteners are not acceptable, including food-service equipment and marine-adjacent installations.
Designed as an OEM-style replacement or stocking fastener for applications requiring a 1/4-28 UNF fine-thread hex jam nut in stainless steel.
Installation is performed by general mechanical, HVAC, plumbing, or electrical trades depending on the application. Always de-energize or depressurize the assembly before servicing any fastened connection. Use a standard open-end or combination wrench sized to 7/16 inches across flats. Do not exceed the torque capacity of stainless steel fasteners, as over-torquing can cause galling on stainless threads.
