Hex jam nuts are thin profile nuts used to lock a standard nut in place or to secure a fastener assembly where axial space is limited. This nut measures 2-1\/4 inches across the flats and stands 27\/32 inches high, conforming to UN thread standards. It is a general-purpose fastener appropriate for mechanical assembly, maintenance, and repair applications across industrial, HVAC, plumbing, and construction trades.\u003c\/p\u003e\u003cp\u003eThis hex jam nut is suited for use in mechanical assemblies requiring a 1-1\/2 inch - 12 UN right-hand thread locknut. The zinc-plated steel construction provides moderate corrosion resistance for indoor and light-duty outdoor environments. It is commonly used in equipment mounting, shaft locking, and structural fastener stacks where a thin nut profile is required to conserve thread engagement space or to serve as a jam-locking element against a primary nut.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/2 inch - 12 UN right-hand thread for standard UN fastener compatibility\u003c\/li\u003e\n\u003cli\u003eHex profile measures 2-1\/4 inches across flats for standard wrench engagement\u003c\/li\u003e\n\u003cli\u003eLow-profile design at 27\/32 inches high for space-limited assemblies\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for conventional tightening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1-1\/2 inch - 12 UN right-hand threaded fasteners and bolts in general mechanical and industrial assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a standard open-end or box wrench sized to the 2-1\/4 inch across-flats dimension.
