It is designed for 5\/8-8 Acme threaded rod or lead screw applications where a left-hand thread direction is required to resist loosening under rotational loads or to serve as part of a counter-threaded assembly. The nut meets a 2G thread fit class, indicating a general-purpose tolerance suitable for most mechanical and industrial applications. Width across flats measures 1-1\/16 inches and height is 39\/64 inches. This fastener is installed by machinists, millwrights, and maintenance technicians working on linear motion systems, machine tools, conveyors, and industrial equipment.\u003c\/p\u003e\u003cp\u003eLeft-hand Acme hex nuts are used in applications where counter-rotation or bidirectional motion requires a left-hand thread to prevent self-loosening. Common install scenarios include lead screw assemblies, jack screws, vises, and actuator mechanisms in commercial and industrial equipment. This nut is not a standard hardware-store item and is specifically selected when a 5\/8-8 Acme left-hand thread is called out in a mechanical design or replacement specification. It is sold individually with a minimum order quantity of one.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand Acme thread prevents loosening in counter-rotating or bidirectional load applications\u003c\/li\u003e\n\u003cli\u003e5\/8-8 Acme thread form provides coarse pitch for efficient linear motion and load transfer\u003c\/li\u003e\n\u003cli\u003e2G thread fit class suits general-purpose mechanical assemblies\u003c\/li\u003e\n\u003cli\u003eSteel construction provides strength and durability in industrial environments\u003c\/li\u003e\n\u003cli\u003e1-1\/16 inches across flats accepts standard open-end or box-end wrenches\u003c\/li\u003e\n\u003cli\u003eHeight of 39\/64 inches provides adequate thread engagement for typical load requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a left-hand Acme thread hex nut for use with 5\/8-8 Acme threaded rod, lead screws, or mating fasteners requiring a left-hand thread direction in industrial and mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician familiar with Acme thread fasteners and left-hand thread engagement. Confirm left-hand thread direction before installation, as forcing a left-hand nut onto a right-hand thread will cause immediate galling and damage to both components. Use an appropriate open-end or box-end wrench sized for 1-1\/16 inches across flats. De-energize and lock out any equipment before servicing lead screw or actuator assemblies per applicable OSHA lockout\/tagout procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-8\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)\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\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161727\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: UM010AG1F001560\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE THREADED PRODUCTS","offers":[{"title":"Default Title","offer_id":67909187240242,"sku":"UM010AG1F001560","price":16.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9376be4df3ca01936c8103dfb6b11473.jpg?v=1791185769","url":"https:\/\/voomisupply.com\/products\/keystone-threaded-products-um010ag1f001560-hex-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
