Built from high-speed steel with a bright uncoated finish, this plug-chamfer tap features four flutes and an H3 thread limit, making it suitable for through-hole tapping applications where chip evacuation is managed manually. It carries a 3B class of fit, which is the standard tolerance class for general-purpose inch-series threaded assemblies. Machinists and tool-and-die professionals reach for this tap when a left-hand thread is required for reverse-torque or counter-rotation fastening situations.\u003c\/p\u003e\u003cp\u003eThis tap is used in machining and fabrication environments where 3\/8-24 UNF left-hand internal threads are needed. The plug chamfer — typically 3 to 5 threads of lead-in — makes it appropriate for through holes or holes with adequate thread runout. It is a single-piece hand or machine tap suited for job shops, maintenance and repair operations, and production machining on materials where high-speed steel provides adequate tool life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand thread direction for reverse-torque and counter-rotation fastening applications\u003c\/li\u003e\n\u003cli\u003e3\/8-24 UNF thread form with 3B class of fit for standard general-purpose tolerance\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for controlled oversize fit on tapped threads\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides 3 to 5 threads of lead-in for through-hole or deep blind-hole use\u003c\/li\u003e\n\u003cli\u003eFour-flute straight flute geometry for use in hand tapping or rigid machine tapping setups\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with bright uncoated finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for any application requiring a 3\/8-24 UNF left-hand internal thread with a 3B class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists or maintenance technicians using a tap wrench, tapping head, or CNC rigid tap cycle. Always ensure the pilot hole is drilled to the correct tap drill diameter for 3\/8-24 UNF before threading. Use appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Because this is a left-hand tap, rotation direction must be reversed from standard tapping procedure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: JY4912242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700976976178,"sku":"JY4912242","price":22.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58a6f19ec100c1f986a1c4101a8ae165.jpg?v=1788396154","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4912242-3-8-24-unf-straight-flute-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
