It features 4 flutes ground from vanadium high-speed steel and carries a titanium nitride (TiN) coating that increases surface hardness and extends tool life in high-cycle production environments. With an overall length of 2.126 inches and a thread length of 0.6875 inches, this tap is sized for small-diameter pipe thread applications. It is used by machinists, pipefitters, and plumbing tradespeople when threading ports, fittings, and manifold bodies to NPT specification.\u003c\/p\u003e\n\u003cp\u003eThis tap suits applications in carbon steel and stainless steel workpieces where a leak-tight NPT thread form is required. Common install scenarios include threading instrument ports, hydraulic manifold inlets, small valve bodies, and HVAC or refrigeration line fittings. The 1\/16-27 NPT thread size is frequently encountered in instrumentation connections, pressure gauge ports, and small-bore gas or fluid lines. It is part of OSG Series 308 and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/16-27 NPT thread form for small-bore pipe thread cutting\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel construction for wear resistance in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction during threading\u003c\/li\u003e\n  \u003cli\u003e4-flute design provides balanced cutting action and chip clearance\u003c\/li\u003e\n  \u003cli\u003eRegular hook geometry suits standard tapping operations\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.126 inches with a 0.3125-inch shank diameter for reliable chuck retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting NPT internal pipe threads in carbon steel and stainless steel workpieces.

Secure the workpiece and use an appropriate cutting fluid for the material being threaded. Apply steady, consistent pressure and back off periodically to clear chips, especially in stainless steel. Verify finished thread fit with a calibrated NPT plug gauge before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/16-27 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.126 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.2340 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.3120 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHook\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Profile\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Carbon Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 308\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.046 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: 1735005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748114596146,"sku":"1735005","price":80.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68139194ba2630418484c761a420be01.jpg?v=1788889225","url":"https:\/\/voomisupply.com\/products\/osg-1735005-npt-pipe-tap-1-16-27-4-flute-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
