Built from cobalt high-speed steel with a steam oxide coating, this bottoming-style tap carries a H6 thread limit and produces 10-24 UNC right-hand threads. At 2.375 inches overall length with a 0.492-inch thread length, it is sized for compact blind-hole applications where a standard or plug chamfer cannot reach full thread depth. Licensed machinists and toolroom technicians install this tap in CNC and manual tapping operations where chip evacuation is a concern.\u003c\/p\u003e\u003cp\u003eThis tap is rated for blind hole threading across a broad range of materials including alloy steel, carbon steel, die steel, hardened steel, aluminum, and stainless steel. The bottoming chamfer of 1 to 1.5 threads makes it the correct choice when full threads are required close to the bottom of a blind hole. It is well-suited for production environments running tight-tolerance fastener holes in 10-24 UNC applications across automotive, aerospace, and general metalworking industries.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design eliminates chips, reducing the risk of chip packing in blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction provides elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating improves lubricity and initial break-in performance\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (1 to 1.5 threads) allows threading to near the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eH6 thread limit ensures consistent fit for standard 10-24 UNC fastener assemblies\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction compatible with standard tapping equipment and toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in blind hole threading of alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

A qualified machinist or toolroom technician should set appropriate tapping speed and apply a suitable cutting or forming fluid for the workpiece material. Secure the tap in a rigid holder to prevent misalignment, and never reverse the tap under power without confirming the machine and toolholder support it. Follow shop safety procedures and applicable OSHA standards when operating tapping equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: 24\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 Limit\u003c\/strong\u003e: H6\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: 0.25 inches\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\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14001)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: 1400157101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51783552958770,"sku":"1400157101","price":30.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d47c58463a9fa709f5972f3ec02a771a.jpg?v=1789190846","url":"https:\/\/voomisupply.com\/products\/osg-1400157101-thread-forming-tap-10-24-unc-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
