Left-hand thread fasteners are used in applications where standard right-hand threads would loosen under operational torque or rotation, such as rotating shafts, fan assemblies, and certain mechanical linkages. The nut measures 0.5 inches across the flats and 17\/64 inches in height, conforming to UNC thread standards. This package contains 100 nuts, suited for maintenance shops, contractors, and field technicians who need a reliable quantity on hand for specialized fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is used in mechanical, HVAC, plumbing, and general trade applications where left-hand thread fasteners are required to prevent self-loosening due to counter-clockwise rotation. Common install scenarios include fan blade retention, bicycle pedal assemblies, and any rotating component where the operational direction would back off a standard right-hand thread. The uncoated finish is appropriate for dry or controlled indoor environments. Grade 2 steel provides adequate tensile strength for light to medium-duty fastening tasks across residential and light commercial work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand thread orientation prevents loosening on counter-rotating components\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread size for broad compatibility with standard left-hand thread applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides reliable light to medium-duty tensile strength\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for use in dry, indoor environments\u003c\/li\u003e\n  \u003cli\u003e0.5 inches across flats, fits standard 1\/2-inch wrench or socket\u003c\/li\u003e\n  \u003cli\u003eSold in a 100-count pack for shop stock or repeat-use applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a left-hand thread replacement or new-install hex nut for mechanical assemblies requiring 5\/16-18 UNC left-hand thread fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLeft-hand thread nuts tighten counter-clockwise and loosen clockwise — always confirm thread direction before installation to avoid cross-threading or stripping. A standard 1\/2-inch wrench or socket is required for proper torque application. Ensure mating fastener threads are also left-hand orientation before assembly. Follow applicable mechanical codes and manufacturer torque guidelines for the specific 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: 5\/16-18\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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 17\/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: HNI5031LH-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701213430066,"sku":"HNI5031LH-100BX","price":2626.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8ce8af4f69b5d7ff46d46df3b1603a3e.jpg?v=1788399971","url":"https:\/\/voomisupply.com\/products\/value-collection-hni5031lh-100bx-hex-nut-5-16-18-lh-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
