It measures 9\/16 inches across flats and 7\/32 inches in height, conforming to Unified National Fine (UNF) thread standards. This nut is used in mechanical assemblies where reverse-thread fastening is required to prevent loosening under rotational forces. Plumbers, pipefitters, HVAC technicians, and general mechanical contractors install left hand thread hardware in applications where standard right hand threads would back out during normal operation. Each box contains 100 nuts.\u003c\/p\u003e\n\u003cp\u003eLeft hand thread hex nuts are specified in applications such as rotating shafts, pedals, turnbuckles, and equipment where counterclockwise rotation would loosen a conventional right hand nut. The 3\/8-24 UNF thread pitch provides fine thread engagement suitable for thin-walled connections and applications requiring precise torque control. Grade 2 steel construction is appropriate for general-purpose mechanical fastening in non-structural and light-duty service environments. This package of 100 nuts is suited for shop stock, maintenance departments, and production assembly use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft hand (LH) thread direction prevents loosening in counterclockwise-rotation applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 UNF thread size for fine-pitch engagement and controlled clamping\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose mechanical service\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish with no added plating or coating\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch width across flats for standard hex wrench and socket fitment\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 100 for shop stock and production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/8-24 UNF left hand thread fastener assemblies in general mechanical, HVAC, plumbing, and light industrial applications where left hand thread hardware is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLeft hand thread nuts are tightened by turning counterclockwise and loosened by turning clockwise — opposite of standard hardware.
