It carries a 2G thread fit class, meaning it meets a standard tolerance range suitable for general-purpose Acme power transmission assemblies. The nut measures 7\/8 inches across flats and stands 31\/64 inches tall. At 0.065 pounds, it is a compact fastener intended for use by machinists, millwrights, and maintenance technicians working on lead screws, feed mechanisms, or actuator assemblies that require reverse-thread engagement to prevent loosening under directional load.\u003c\/p\u003e\u003cp\u003eThis hex nut is appropriate for industrial and commercial applications where a left-hand Acme thread is specified to counteract rotational forces that would otherwise back off a standard right-hand fastener. Typical installations include linear actuators, machine tool lead screws, valve stems, and similar power transmission components. The 303 stainless steel construction makes it suitable for environments with moderate corrosion exposure, such as food processing equipment supports, marine hardware assemblies, or chemical plant fixtures where non-magnetic, corrosion-resistant fasteners are preferred.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand Acme thread (1\/2-10) prevents loosening under reverse rotational load\u003c\/li\u003e\n\u003cli\u003eGrade 303 stainless steel provides corrosion resistance and machinability\u003c\/li\u003e\n\u003cli\u003e2G thread fit class ensures standard tolerance for general Acme power transmission use\u003c\/li\u003e\n\u003cli\u003e7\/8 inch across-flats width fits standard hex tooling\u003c\/li\u003e\n\u003cli\u003eDoes not meet military specifications  -  intended for commercial and industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1\/2-10 Acme left-hand threaded rods, lead screws, or mating components carrying a 2G fit class tolerance.

Left-hand threads tighten counterclockwise  -  torque in the correct direction to avoid cross-threading or stripping the mating component. Inspect the mating lead screw or threaded rod for burrs or contamination before engagement. Use appropriate hex tooling sized to 7\/8 inches across flats.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 303\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\u003eWeight\u003c\/strong\u003e: 0.065 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: US008AG1F001265\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE THREADED PRODUCTS","offers":[{"title":"Default Title","offer_id":67912185708850,"sku":"US008AG1F001265","price":43.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6f6ece345c37f115a9de1da8956b4ba_c2a97eaf-3ba0-40b9-a073-24c82340667c.jpg?v=1791229175","url":"https:\/\/voomisupply.com\/products\/keystone-us008ag1f001265-hex-nut-1-2-10-acme-303-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
