Unlike cutting taps, this forming tap displaces metal to produce threads, resulting in stronger thread forms with no chips to clear from the hole. Built from high-speed steel with a bright uncoated finish, it is suited for use in softer workpiece materials. The H7 thread limit and 2B class of fit make it compatible with standard UNF fastener assemblies. It measures 2.9375 inches in overall length with a shank diameter of 0.381 inches, fitting standard tap handles and machine tool holders used in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis tap is specified for blind hole threading applications where a 3\/8-24 UNF internal thread is required. The bottoming chamfer style, with 2.5 chamfered threads, allows threading close to the bottom of a blind hole. It is used in machining, maintenance, and repair operations across manufacturing, toolroom, and field service environments. Licensed machinists, tool and die makers, and maintenance technicians working with ferrous and non-ferrous materials in the softer hardness range are the typical end users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming action displaces material rather than cutting, producing stronger threads with no chip generation\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 2.5P allows threading close to the base of a blind hole\u003c\/li\u003e\n\u003cli\u003eH7 thread limit ensures consistent 2B class of fit for standard UNF fastener compatibility\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability in production tapping operations\u003c\/li\u003e\n\u003cli\u003eSingle oil groove supports lubrication delivery during the forming process\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for standard tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in blind hole threading applications requiring a 3\/8-24 UNF internal thread with a 2B class of fit.

Secure the workpiece and ensure proper alignment to avoid tap breakage. Apply appropriate tapping fluid or cutting oil rated for the workpiece material before and during the tapping operation. Thread forming taps are not suitable for use in hard or brittle materials; consult material hardness ratings before specifying this tap for a given application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2.5P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eOverall Length\u003c\/strong\u003e: 2.9375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.9500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3810 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.2860 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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: BXB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BALAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13627-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51972094722354,"sku":"13627-010","price":47.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3fb9859a79b310cd9cf492ba7306c2f1.jpg?v=1789962641","url":"https:\/\/voomisupply.com\/products\/balax-13627-010-thread-forming-tap-3-8-24-unf-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
