It carries a 2G thread fit class, indicating a general-purpose commercial tolerance suitable for most power-transmission and linear-motion applications. The nut measures 0.5 inches across the flats and stands 15\/64 inches tall, with a right-hand thread direction. At approximately 0.012 pounds, it is a lightweight fastener intended for use wherever a standard Acme thread nut is specified. Licensed tradespeople, machinists, and maintenance technicians commonly source this nut for lead screw assemblies, adjusting mechanisms, and fixture work.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is sized for 1\/4-16 Acme thread rod or lead screw stock. The Acme thread profile is standard in linear-motion and power-transmission assemblies, including machine tool slides, vises, jigs, and valve stems. The 1215\/12L14 steel grade provides adequate strength for light-duty clamping and positioning loads in non-corrosive environments. It does not meet military specifications and is not intended for critical structural or high-cycle fatigue applications. Maintenance techs and industrial mechanics will find it appropriate for replacing worn nuts on existing Acme lead screws without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-16 Acme thread profile for use with standard Acme lead screw stock\u003c\/li\u003e\n  \u003cli\u003e2G thread fit class for general-purpose commercial tolerance and reliable mating\u003c\/li\u003e\n  \u003cli\u003e1215\/12L14 free-machining leaded steel for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, the most common orientation in linear-motion assemblies\u003c\/li\u003e\n  \u003cli\u003e0.5 inches across flats, compatible with standard 1\/2-inch wrenching\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.012 pounds, suitable for compact mechanism packaging\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4-16 Acme threaded rod or lead screw stock in light-duty linear-motion and power-transmission assemblies where a 2G fit class hex nut is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance mechanics familiar with Acme thread assemblies. De-energize and lock out any equipment before replacing a lead screw nut. Hand-start the nut onto the Acme thread to confirm correct engagement before applying a wrench to avoid cross-threading. Inspect the mating lead screw for wear before installing a new nut, as worn screw threads will accelerate nut wear regardless of nut condition.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Acme\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 2G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Nut\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 \/ 12L14\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: 15\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.012 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: UM004AG1A000580\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE THREADED PRODUCTS","offers":[{"title":"Default Title","offer_id":67907280798002,"sku":"UM004AG1A000580","price":16.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6f6ece345c37f115a9de1da8956b4ba_f2febb54-84d0-4df0-8ea1-963dfd2a1e7e.jpg?v=1791176419","url":"https:\/\/voomisupply.com\/products\/keystone-threaded-products-um004ag1a000580-hex-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
