Built from high-speed steel with a nitride and oxide combination coating, this tap is suited for production threading in ferrous and non-ferrous materials. The plug chamfer  -  typically 3 to 5 threads  -  makes it the standard choice for through-hole threading where partial thread lead-in is acceptable. With an H3 thread limit and 4 flutes, it delivers controlled fit tolerances and stable chip evacuation in moderate-duty tapping operations. Licensed machinists, toolroom techs, and maintenance mechanics are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for threading aluminum and cast iron and fits standard tapping chucks and hand-tap wrenches accepting the 0.442-inch square drive. The 101C series designation places it within OSG's general-purpose straight flute line. At 4.25 inches overall length with a 2-inch thread length and a neck length of 2.22 inches, it has sufficient reach for most through-hole and shallow blind-hole applications in those material classes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-10 UNC right-hand thread form for standard unified coarse series fastener preparation\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for controlled tolerance fits in production and maintenance threading\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness across a range of cutting speeds\u003c\/li\u003e\n  \u003cli\u003eNitride and oxide coating reduces friction and improves surface lubricity during cutting\u003c\/li\u003e\n  \u003cli\u003e4-flute straight design aids chip control in through-hole tapping of aluminum and cast iron\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style suits through-hole applications requiring moderate lead-in\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum and cast iron.

Align the tap perpendicular to the work surface before starting to avoid thread cross-threading or tap breakage. Use a calibrated tapping chuck or T-handle tap wrench matched to the square drive size. Remove the tap periodically to clear chips when working in deeper holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 10\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 2.22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Drive Size\u003c\/strong\u003e: 0.442 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.6875 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\u003c\/strong\u003e: Nitride and Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Iron\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: 101C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 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: 1604307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743294128434,"sku":"1604307","price":94.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfe42b3ffcdc3e02ca3435f426e0878d.jpg?v=1788845212","url":"https:\/\/voomisupply.com\/products\/osg-1604307-straight-flute-tap-3-4-10-unc-hss-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
