Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips. Manufactured from high speed steel with a bright finish, this tap is suited for blind hole threading in ductile materials. It measures 2.125 inches overall length with a thread length of 0.374 inches and a shank diameter of 0.168 inches. The bottoming chamfer of 1.5 to 2 threads allows threading close to the bottom of a blind hole. Right hand thread direction applies.\u003c\/p\u003e\u003cp\u003eThis tap is intended for blind hole threading operations in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. It is commonly used in production machining, maintenance and repair, and fabrication environments where 8-32 UNC fastener holes are required in ductile workpiece materials. The bottoming geometry is particularly useful when full thread engagement depth is needed near the base of a drilled hole. Part of the OSG HY-PRO NRT series, it is packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer with 1.5 to 2 chamfered threads for threading close to blind hole bases\u003c\/li\u003e\n\u003cli\u003eThread forming design displaces material instead of cutting — eliminates chips and produces stronger threads\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across a range of ductile metals\u003c\/li\u003e\n\u003cli\u003eBright finish, no coating — allows visual wear inspection\u003c\/li\u003e\n\u003cli\u003eRight hand thread direction, 32 threads per inch, 8-32 UNC\u003c\/li\u003e\n\u003cli\u003eSquare drive end: 0.131 inches square size, 0.250 inches square length for positive tap wrench engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel workpieces requiring 8-32 UNC, 2B class of fit threads. Not recommended for cast iron, hardened steel, or non-ductile materials where thread forming taps are not applicable.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a dedicated forming tap drill size — not the standard tap drill for cutting taps — so verify the correct pilot hole diameter before use. Secure the workpiece and use a calibrated tap wrench or CNC tapping head set to the appropriate feed rate for the material. Apply cutting fluid or tapping lubricant appropriate for the workpiece material to reduce forming forces and extend tap life. If tapping by hand, advance with steady forward pressure and back off periodically to relieve stress.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1.5 to 2P\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: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\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: Aluminum, Cast Aluminum, Low-Carbon Steel, Medium-Carbon 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: 285 (HY-PRO NRT)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 2865200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728170352946,"sku":"2865200","price":30.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d153079950a79d44d5f3d63914caea9.jpg?v=1788688901","url":"https:\/\/voomisupply.com\/products\/osg-2865200-thread-forming-tap-8-32-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
