It measures 9\/16 inches across the flats and 21\/64 inches in height, conforming to UNC thread standards. Left-hand thread fasteners are specified in applications where standard right-hand rotation would cause a nut to loosen under operational torque — such as rotating shafts, pedal assemblies, and certain equipment anchoring points. This package contains 100 nuts and is sold as a single packaged unit weighing 1 pound. Plumbers, HVAC technicians, electricians, and general tradespeople stock these for specialty fastener needs on the job.\u003c\/p\u003e\n\u003cp\u003eLeft-hand thread hex nuts in 3\/8-16 UNC are used in mechanical assemblies where counter-rotation forces are present. Common applications include equipment tie-downs, fan blade retention hardware, bicycle components, industrial machinery, and any installation where a conventionally threaded fastener would back out under service conditions. The Grade 2 steel construction suits general-purpose, non-structural fastening in both residential and light commercial settings where high-tensile fasteners are not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand UNC thread prevents loosening under counter-clockwise rotational forces\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 thread size fits standard 3\/8-inch left-hand threaded fastener applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose, light-duty fastening\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for standard indoor or protected installations\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch across-flats dimension accepts standard 9\/16-inch wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003ePack of 100 nuts for job-site inventory and bulk repairs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/8-16 UNC left-hand threaded bolts and studs in general mechanical and trade applications where left-hand fastener engagement is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLeft-hand thread nuts tighten counter-clockwise and loosen clockwise — confirm thread direction before installation to avoid cross-threading or stripping. Use a properly sized 9\/16-inch wrench or socket for installation; avoid over-torquing Grade 2 fasteners, as they have lower tensile strength than Grade 5 or Grade 8 hardware. De-energize or lock out any equipment before accessing rotating assemblies that use left-hand fasteners. Follow applicable mechanical codes and manufacturer torque guidelines for the assembly being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 21\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HNI5037LH-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693808910642,"sku":"HNI5037LH-100BX","price":3825.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f120eed118a1878a028c3427e66a228.jpg?v=1788317621","url":"https:\/\/voomisupply.com\/products\/value-collection-hni5037lh-100bx-hex-nut-3-8-16-lh-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
