It carries a 2G fit class, indicating a general-purpose Acme thread tolerance suitable for power transmission and linear motion applications. The nut measures 1-13\/16 inches (1.8125 inches decimal) across the flats and stands 1-7\/64 inches tall. At 0.63 pounds, it is a substantial fastener suited for heavy mechanical assemblies. Machinists, millwrights, and maintenance technicians working with lead screws, jack screws, or linear actuator systems are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis hex nut is designed for use in industrial and mechanical assemblies where Acme-thread fasteners are specified. Common applications include jack screws, vises, press frames, linear actuators, and other power-screw mechanisms that require controlled axial movement under load. The right-hand thread direction is standard for the vast majority of these assemblies. The 2G fit class provides adequate clearance for smooth engagement while maintaining acceptable backlash control in general-purpose power-screw applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAcme thread form with 1-1\/8-5 thread size for power transmission duty\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for standard mechanical assembly orientation\u003c\/li\u003e\n\u003cli\u003e2G thread fit class providing general-purpose Acme thread tolerance\u003c\/li\u003e\n\u003cli\u003e1-13\/16 inch width across flats for use with standard heavy hex tooling\u003c\/li\u003e\n\u003cli\u003eSteel construction for strength and durability in industrial environments\u003c\/li\u003e\n\u003cli\u003eDoes not meet military specifications  -  commercial grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or stock hex nut for assemblies specifying a 1-1\/8-5 Acme right-hand thread with a 2G fit class tolerance.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using an open-end or box-end wrench sized for a 1-13\/16 inch across-flats dimension. Ensure mating lead screw or threaded rod also carries a compatible 1-1\/8-5 Acme 2G thread profile before installation. Disengage and de-energize any associated drive or load mechanism before servicing the threaded assembly. Do not use impact tooling on Acme-thread nuts, as it can damage the thread form and degrade fit class tolerances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/8-5\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\u003eWidth Across Flats\u003c\/strong\u003e: 1-13\/16 inches (1.8125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-7\/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: 0.63 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\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: UM018AG1A002845\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE THREADED PRODUCTS","offers":[{"title":"Default Title","offer_id":67906494955826,"sku":"UM018AG1A002845","price":25.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63b6c2d5ee3933aaa64f465097717a6c.jpg?v=1791168602","url":"https:\/\/voomisupply.com\/products\/keystone-threaded-products-um018ag1a002845-hex-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
