Sized at 3\/8-24 UNF with three flutes and a plug chamfer, this tap follows the Unified National Fine thread standard and is manufactured from high-speed steel for durability under repeated use. It carries a 3B class of fit and an H3 thread limit, making it suitable for applications where consistent, close-tolerance threading is required. Thread length is 1.25 inches and overall length is 2.9375 inches. Machinists, maintenance technicians, and tool-and-die professionals typically use this tap in manual or machine tapping operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. The plug chamfer style  -  featuring a moderate lead-in of several tapered threads  -  makes it appropriate for through-hole and moderately deep blind-hole applications where a starting tap has already been used or where material conditions allow direct engagement. It fits standard tap handles and machine tool collets compatible with the 3\/8-24 shank size and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF thread form with 3B class of fit for close-tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent fit across production runs\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides a balanced lead-in suitable for through-holes and moderately deep blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles ferrous and non-ferrous materials including cast iron and various carbon steels\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, the standard orientation for general-purpose threading\u003c\/li\u003e\n  \u003cli\u003eThree flutes promote chip evacuation in short-chipping materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel.

Apply appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. For machine tapping, set spindle speed according to material and tap diameter recommendations from the tooling manufacturer. Avoid over-torquing in hand-tapping operations, especially in softer materials like aluminum, to prevent tap 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\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: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\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: 1171602\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740261613874,"sku":"1171602","price":38.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3005a3241a07a05916939403d90790a.jpg?v=1788823837","url":"https:\/\/voomisupply.com\/products\/osg-1171602-straight-flute-tap-3-8-24-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
