Ground from high-speed steel with a bright uncoated finish, this tap produces right-hand 8-32 UNC threads with 4 flutes. The bottoming chamfer  -  typically 1 to 2 thread leads  -  allows threading into the full depth of a blind hole after a taper or plug tap has started the thread. The H1 thread limit designation indicates a tight tolerance fit, keeping the tapped thread close to the nominal pitch diameter. Overall length is 2.125 inches with a thread length of 0.469 inches.\u003c\/p\u003e\u003cp\u003eThis tap is suited for low-volume production and maintenance work in machine shops, tool rooms, and field repair environments. It is appropriate for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. The 8-32 UNC size is a common fastener standard found in electrical panels, electronic enclosures, light mechanical assemblies, and general fabrication work. It is typically installed in a tap wrench, hand-tapping fixture, or low-speed machine spindle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for use in a range of ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eH1 thread limit for close-tolerance fit near nominal pitch diameter\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across general-purpose applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish  -  no coating buildup to affect thread tolerance\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, Series 102\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style hand or machine tap for general-purpose internal thread cutting in materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel where an 8-32 UNC bottoming tap is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a calibrated tap wrench or low-speed tapping machine  -  hand-tapping is common for repair and one-off work. Always use cutting fluid appropriate to the workpiece material to extend tap life and improve thread quality. Ensure the correct tap drill size for 8-32 UNC is used before tapping. When tapping blind holes, clear chips frequently to prevent tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H1\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: 0.469 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.934 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 Length\u003c\/strong\u003e: 0.25 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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 102\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 1004400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740495806770,"sku":"1004400","price":21.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eadf4c4a0edb283045a307b099a8ee3b.jpg?v=1788825414","url":"https:\/\/voomisupply.com\/products\/osg-1004400-straight-flute-tap-8-32-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
