It carries a 5\/8-6 Acme thread form with a 2G fit class, making it suitable for precision linear motion assemblies and power transmission applications. The 1-1\/16 inch across-flats dimension accepts a standard open-end or box wrench. At 0.119 pounds, the nut is a compact fastener intended for use wherever a left-hand thread is required to resist loosening under counter-clockwise rotational loads or to meet specific mechanical design requirements. Licensed mechanics, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is used in industrial machinery, lead screw assemblies, actuators, and mechanical systems that specify Acme thread profiles for load-bearing or positioning functions. The left-hand thread direction is critical and must be matched to a corresponding left-hand threaded rod or lead screw. The 2G fit class indicates a general-purpose commercial tolerance suitable for the majority of power transmission and positioning applications. It is not rated to meet military specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand Acme thread direction for counter-clockwise drive applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-6 Acme thread size with 2G commercial fit class\u003c\/li\u003e\n  \u003cli\u003e1215 and 12L14 free-machining steel construction for consistent threading quality\u003c\/li\u003e\n  \u003cli\u003e1-1\/16 inch width across flats for standard wrench compatibility\u003c\/li\u003e\n  \u003cli\u003e39\/64 inch height for compact axial footprint in tight assemblies\u003c\/li\u003e\n  \u003cli\u003eDoes not meet military specifications  -  commercial grade application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/8-6 Acme left-hand threaded rods and lead screws requiring a 2G fit class in industrial and mechanical power transmission assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, machinist, or maintenance technician familiar with Acme thread systems. Confirm the mating threaded component is also a left-hand thread before assembly  -  cross-threading a left-hand nut onto a right-hand lead screw will damage both parts. Use the appropriate wrench size across the 1-1\/16 inch flats and do not apply excessive torque beyond what the assembly design specifies. Degrease mating surfaces if thread-locking compound or lubrication is called for in the equipment service documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Acme\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 2G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/16 inches (1.0625 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 39\/64 inches\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: 1215 and 12L14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.119 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does not meet military specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161727\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: KEYSTONE THREADED PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UM010AG1F001550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE THREADED PRODUCTS","offers":[{"title":"Default Title","offer_id":67914291314994,"sku":"UM010AG1F001550","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6f6ece345c37f115a9de1da8956b4ba_f7829372-d1be-4a0c-a6bf-62278ec4e13b.jpg?v=1791248469","url":"https:\/\/voomisupply.com\/products\/keystone-threaded-products-um010ag1f001550-hex-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
