Jam nuts are thin hex nuts used to lock a standard nut in place or to secure a threaded fastener in applications where a full-height nut would interfere with assembly. At 3\/16 inches tall and 1\/2 inch across the flats, this nut seats against a mating nut or surface to prevent loosening under vibration or torque. The right-hand thread follows standard UNF conventions. Electricians, plumbers, HVAC technicians, and general trade mechanics use jam nuts throughout panel mounting, equipment bracing, and threaded-rod assemblies.\u003c\/p\u003e\n\u003cp\u003eThis jam nut is suited for residential and light commercial trade applications wherever a 5\/16-24 UNF threaded fastener requires a locking or positioning nut. Common use cases include conduit support hardware, equipment mounting frames, valve stem lockouts, and threaded-rod strut channel assemblies. The uncoated finish is appropriate for dry or indoor environments. This SKU is sold as a single nut with a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eJam nut profile at 3\/16 inches height for low-clearance locking applications\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNF right-hand thread for standard inch fine-thread compatibility\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose mechanical fastening\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch across flats fits standard 1\/2 inch open-end or box wrench\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suited for dry indoor installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or supplemental jam nut for any assembly using a 5\/16-24 UNF threaded fastener requiring a locking nut.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/2 inch open-end wrench or combination wrench.
