It is manufactured from 1215\/12L14 leaded free-machining steel, offering consistent machinability and reliable thread engagement under load. The nut carries a 2G thread fit class on a 1\/2-10 Acme thread profile, making it suitable for linear-motion and power-transmission applications where left-hand thread orientation is required. With a width across flats of 7\/8 inches and a height of approximately 31\/64 inches, it mates with standard hex tooling. Machinists, millwrights, and maintenance technicians working on jacks, lead screws, and actuator assemblies are the primary installers of this fastener.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is used in industrial and mechanical assemblies that require left-hand Acme thread engagement to prevent back-driving or to match existing left-hand threaded rod and lead screw configurations. Typical applications include machine tool lead screws, linear actuators, vises, and lifting jacks where a 1\/2-10 Acme thread form is specified. It is not intended for standard unified or metric fastener applications. The 1215\/12L14 steel grade is suited for moderate-load, non-corrosive environments and is commonly found in light industrial and OEM fabrication settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand Acme thread orientation prevents accidental loosening in back-driving assemblies\u003c\/li\u003e\n  \u003cli\u003e1\/2-10 Acme thread profile matches standard lead screw and jack shaft configurations\u003c\/li\u003e\n  \u003cli\u003e2G thread fit class provides a standard clearance fit for reliable mating\u003c\/li\u003e\n  \u003cli\u003e1215\/12L14 free-machining steel enables precise thread form and consistent tolerances\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch width across flats accepts standard hex wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eCompact 31\/64-inch height suits space-constrained assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2-10 Acme left-hand threaded rod, lead screws, and actuator shafts requiring a 2G thread fit class in light industrial or OEM mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians familiar with Acme thread systems. Confirm left-hand thread direction before assembly  -  left-hand nuts tighten counterclockwise. Use a calibrated torque wrench and appropriate hex socket; avoid impact tools that may gall the 12L14 steel thread form. Inspect mating threads for wear or contamination before installation to ensure proper 2G fit engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-10\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: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 31\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 1215\/12L14 Free-Machining Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.065 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: UM008AG1F001265\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE THREADED PRODUCTS","offers":[{"title":"Default Title","offer_id":67906374369586,"sku":"UM008AG1F001265","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c08bc610b1f4eecb1d1b0e87ee6e126.jpg?v=1791167651","url":"https:\/\/voomisupply.com\/products\/keystone-threaded-products-um008ag1f001265-hex-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
