It measures 0.75 inches across the flats and 7\/16 inches in height, conforming to standard hex nut geometry for use with a 3\/4-inch wrench. Left-hand thread direction means the nut tightens counterclockwise, making it suited for applications where standard right-hand fasteners would loosen under rotational load. This box of 100 nuts is used by maintenance technicians, pipefitters, millwrights, and general contractors on mechanical assemblies requiring left-hand fastener configurations.\u003c\/p\u003e\n\u003cp\u003eLeft-hand thread hex nuts in 1\/2-20 UNF are typically found in mechanical drive systems, rotating shaft assemblies, and equipment where vibration or rotational direction would back off a conventional fastener. Common applications include industrial machinery, automotive components, specialty equipment mounting, and replacement fastener work where OEM assemblies specified left-hand thread hardware. This box quantity of 100 units supports production, maintenance, or repair environments with recurring fastener demand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand thread direction prevents loosening in counterclockwise-rotating assemblies\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF thread form for fine-pitch engagement and improved load distribution\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general mechanical and structural fastening\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no added plating that could affect dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003e0.75 inches across flats, compatible with standard 3\/4-inch hex tooling\u003c\/li\u003e\n  \u003cli\u003eBox of 100 units reduces per-unit cost for production and maintenance stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2-20 UNF left-hand thread fasteners and mating bolts or studs in the same thread standard.

Use a calibrated torque wrench sized for 3\/4-inch hex drive and follow the applicable torque specification for Grade 2 steel in the equipment service documentation. Inspect mating threads for damage or contamination before assembly. Do not mix left-hand and right-hand thread fasteners in the same joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7\/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\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: HNFI5050LH-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692557697330,"sku":"HNFI5050LH-100BX","price":9414.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66e15ea332f7514c8a8260eb6cd6a7ff.jpg?v=1788299250","url":"https:\/\/voomisupply.com\/products\/value-collection-hnfi5050lh-100bx-hex-nut-1-2-20-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
