It is sized for 5\/16-14 Acme thread applications and carries a 2G thread fit class, indicating a standard commercial tolerance suitable for general mechanical assemblies. At 0.017 pounds, this is a lightweight fastener intended for precision threaded connections where left-hand thread engagement is required to resist counter-clockwise loosening forces. Machinists, millwrights, and mechanical assembly technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is suited for use in industrial machinery, actuator assemblies, lead screw mechanisms, and other applications that call for Acme-profile left-hand threaded fasteners. The 5\/16-14 Acme thread standard is common in linear motion systems, jigs, fixtures, and feed mechanisms. The 1215\/12L14 steel grade offers good machinability and is frequently specified in precision-turned component applications. This part does not meet military specifications and is intended for commercial and industrial use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand Acme thread at 5\/16-14 resists counter-clockwise loosening in rotating or vibrating assemblies\u003c\/li\u003e\n  \u003cli\u003eThread fit class 2G provides standard commercial tolerance for reliable mating with compatible Acme-threaded rods or screws\u003c\/li\u003e\n  \u003cli\u003e1215\/12L14 free-machining steel construction offers consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch width across flats accepts standard hex wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eHeight of 19\/64 inch keeps the profile compact for space-constrained assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/16-14 Acme left-hand threaded rods, screws, or shafts in commercial and industrial mechanical assemblies requiring a 2G fit class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or mechanical assembly technicians using a standard 9\/16-inch hex wrench or socket. Always de-energize and lock out any machinery before servicing threaded components in live assemblies. Verify that the mating thread is also a left-hand Acme profile before installation to avoid cross-threading or thread damage. Do not apply standard right-hand torque references to left-hand fasteners without confirming thread direction first.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\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\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: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 19\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.017 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: UM005AG1F000775\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE THREADED PRODUCTS","offers":[{"title":"Default Title","offer_id":67909711167794,"sku":"UM005AG1F000775","price":38.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6f6ece345c37f115a9de1da8956b4ba_8f225d7b-c34a-48ff-8e29-30d6cd07df96.jpg?v=1791190275","url":"https:\/\/voomisupply.com\/products\/keystone-um005ag1f000775-hex-nut-5-16-14-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
