Unlike cut taps, thread forming taps displace material rather than remove chips, producing stronger threads with a burnished finish. Built from cobalt high-speed steel and finished with a steam oxide coating, this tap handles demanding materials including alloy steel, carbon steel, stainless steel, hardened steel, die steel, and aluminum. It is configured for 10-32 UNF threads with a modified bottoming chamfer of 2 to 2.5 chamfered threads, making it well suited for threading close to the bottom of blind holes. Licensed machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThis tap is intended for blind hole threading in production and maintenance machining environments. The 10-32 UNF thread size is common in precision assemblies across aerospace, industrial equipment, and electronics manufacturing where fine-pitch threads are required in tight spaces. The modified bottoming chamfer allows threading nearer to the bottom of a blind hole compared to a standard plug chamfer. Material application codes P and N confirm suitability across a broad range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material rather than cutting chips, reducing breakage risk and improving thread strength\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction provides heat and wear resistance in tough materials including stainless and hardened steels\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating improves lubricity and helps resist galling during the forming process\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads allows threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eClass 3B fit with H4 thread limit for tight, accurate thread tolerance\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction in 10-32 UNF for standard fastener compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole thread forming applications in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Adequate lubrication or cutting fluid appropriate for the workpiece material is essential to prevent galling and tap failure. Secure the workpiece and use a calibrated torque-controlled tapping head or CNC spindle where possible to avoid overloading the tap. Always follow applicable shop safety procedures and ensure the spindle is fully stopped before handling the tap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32 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: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5P\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: H4\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: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.492 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.866 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.152 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.250 inches\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: HY-PRO NRT 14001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1400120401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733043151154,"sku":"1400120401","price":30.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb081f67ab5ee1e805e7e7f60940e97d.jpg?v=1788750901","url":"https:\/\/voomisupply.com\/products\/osg-1400120401-thread-forming-tap-10-32-unf-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
