It features a plug chamfer style, 4 straight flutes, and a right-hand thread direction with a 29-degree thread angle — the standard for Acme thread forms. Built from high-speed steel with a bright uncoated finish, this tap delivers consistent performance in threading operations on steel, aluminum, and similar materials. The 2-1\/4-inch thread length and 4-1\/4-inch overall length make it suitable for through-hole and moderate-depth blind-hole applications. It carries a 2G class of fit, indicating a general-purpose tolerance appropriate for most power-transmission and linear-motion thread applications. Machinists, toolmakers, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for cutting Acme threads in power screws, lead screws, feed mechanisms, and similar components found in industrial machinery, machine tools, and mechanical assemblies. The 3\/8-12 designation refers to a 3\/8-inch major diameter with 12 threads per inch — a common size in light-duty linear actuation and feed screw applications. The plug chamfer style (typically 3-5 threads of chamfer relief) is appropriate for through-hole threading and is the most common general-purpose chamfer type. The straight flute design is best suited for threading in through holes or short blind holes in most ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-12 Acme thread form with a 29-degree thread angle for standard power-transmission thread profiles\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for balanced cutting action and chip clearance in through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style for versatile general-purpose threading\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for compatibility with cutting oils and standard lubrication practices\u003c\/li\u003e\n  \u003cli\u003e2G class of fit for general-purpose Acme thread tolerance requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Acme thread tap for cutting 3\/8-12 right-hand internal Acme threads in standard machine shop and maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAcme thread taps are installed by machinists using a tap wrench, tapping head, or CNC machine spindle. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Ensure the tap is started square to the workpiece to prevent thread misalignment or tap breakage. Never reverse-thread a tap without relieving cutting pressure, and inspect flutes for chip loading between passes on deeper holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Angle\u003c\/strong\u003e: 29 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY4792123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722725097778,"sku":"JY4792123","price":176.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3295eec1f8189e2b83dd6d1e2b4d96ae.jpg?v=1788595010","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4792123-acme-thread-tap-3-8-12-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
