Sized at 3\/8-16 UNC with a bottoming chamfer of 1 to 1.5 threads, it is suited for threading blind holes where maximum thread depth is required. Constructed from cobalt with a bright finish, the tap carries a Thread Limit of H7 and handles right-hand thread direction. It is installed by machinists and tool-and-die professionals in production and maintenance environments requiring precise, chip-free threading.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. Its application is blind hole threading, making it a practical choice for close-tolerance work in both job shop and production floor settings. The bottoming chamfer allows threading close to the bottom of a blind hole, maximizing usable thread length in components where through-hole design is not an option.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design cold-forms threads without cutting chips, reducing tap breakage risk in blind holes\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer with 1 to 1.5 chamfered threads for maximum thread depth in blind hole applications\u003c\/li\u003e\n  \u003cli\u003eCobalt construction provides heat and wear resistance in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003eH7 thread limit for consistent, close-tolerance thread form\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; suitable for use with surface-applied cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces with material application codes P and N.

Power down and secure the workpiece before beginning any tapping operation. Apply a suitable tapping fluid or paste lubricant to the tap and workpiece to reduce friction and extend tool life. Use a tapping attachment or CNC rigid tapping cycle to maintain axial alignment and avoid 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\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.252 inches\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 Size\u003c\/strong\u003e: 0.286 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\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14001)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.086 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: 1400134700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728649584946,"sku":"1400134700","price":41.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_c0e48ae9-0d1c-44d9-8bf4-072b1bb9357d.jpg?v=1788694409","url":"https:\/\/voomisupply.com\/products\/osg-1400134700-thread-forming-tap-3-8-16-unc-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
