It produces a 3\/8-24 UNF right-hand thread to a 3B class of fit, making it suitable for applications that require a standard tolerance internal thread. The tap features three flutes, a plug chamfer for general-purpose through-hole and blind-hole tapping, and an H3 thread limit for consistent sizing. Manufactured from high-speed steel with a bright uncoated finish, it is a reliable choice for production and maintenance machining operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for hand or machine tapping in materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. It is well suited to general metalworking shops, maintenance and repair operations, and production environments where 3\/8-24 UNF threaded holes are required. The plug chamfer makes it a versatile starting point for most tapping scenarios, providing a gradual thread lead-in that distributes cutting forces across several teeth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF thread form with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003e3B class of fit and H3 thread limit for standard tolerance control\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for use in through holes and accessible blind holes\u003c\/li\u003e\n  \u003cli\u003eThree-flute geometry for chip management in a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with bright uncoated finish\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through feature; suitable for conventional flood or manual lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for tapping 3\/8-24 UNF threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces.

Ensure the workpiece is securely clamped and the tap is aligned perpendicular to the drilled hole before applying cutting pressure. Apply a suitable cutting fluid for the workpiece material to extend tap life and improve thread finish. Power down or disengage the machine before removing the tap from a blind hole to avoid breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/4 inches (0.937 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches (2.937 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.286 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.4134 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\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 103\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1171600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51741478388018,"sku":"1171600","price":33.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b85c723c9e6bc979ee14eef670bb6b61.jpg?v=1788831721","url":"https:\/\/voomisupply.com\/products\/osg-1171600-straight-flute-tap-3-8-24-unf-plug-3b-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
