It measures 0.5 inches across the flats and 3\/16 inches in height, conforming to UNC thread standards. Left-hand thread fasteners turn counterclockwise to tighten, making them the correct choice for applications where standard right-hand nuts would loosen under rotation or vibration. This nut is sold in a box of 100 units and is a general-purpose industrial fastener suited for mechanical assemblies, equipment maintenance, and trade installations requiring left-hand thread components.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is used in applications where left-hand threading is required to prevent self-loosening due to rotational forces. Typical use cases include fan blade assemblies, rotating shafts, pedal spindles, and machinery where counterclockwise shaft rotation would back off a standard right-hand fastener. Plumbers, HVAC technicians, electricians, and general mechanical contractors working on rotating equipment or specialty assemblies will encounter this requirement. The 5\/16-18 UNC thread size is a common fractional thread found across a wide range of light- to medium-duty mechanical systems. The 100-piece box quantity supports shop stock and job-site inventory needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand thread direction prevents loosening under counterclockwise rotation\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread size for compatibility with standard fractional fastener systems\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate tensile strength for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for dry interior applications or where coating would interfere with fit\u003c\/li\u003e\n  \u003cli\u003e0.5 inches across flats accepts a standard 1\/2-inch wrench or socket\u003c\/li\u003e\n  \u003cli\u003ePackaged in a 100-piece box for bench stock and job-site replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/16-18 UNC left-hand thread bolts and studs in general mechanical and trade assemblies requiring left-hand thread fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLeft-hand thread fasteners tighten counterclockwise and loosen clockwise — confirm thread direction before installation to avoid cross-threading or stripping. Power down or de-energize any equipment before servicing fasteners on mechanical assemblies. A standard 1\/2-inch wrench or socket is required for installation and removal. Follow applicable equipment manufacturer torque guidelines; do not estimate torque values from fastener grade alone without referencing the appropriate specification.\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: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound (per package)\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: JNI2031LH-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690879910194,"sku":"JNI2031LH-100BX","price":5833.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bec4abe49a17b454623f1a6fe30765a.jpg?v=1788276848","url":"https:\/\/voomisupply.com\/products\/value-collection-jni2031lh-100bx-hex-nut-5-16-18-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
