Built from cobalt high speed steel with a V-coating finish, this plug-style tap produces internal threads by displacing material rather than cutting chips, making it well-suited for tough and ductile workpiece materials. It measures 3.937 inches overall length with a shank diameter of 0.323 inches and a tapping depth of 1.693 inches. Licensed machinists and precision tooling shops rely on this tap for consistent thread quality in production environments.\u003c\/p\u003e\n\u003cp\u003eThe OSG 1625076248 is rated for a broad range of material applications including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium. Its plug chamfer style with 4 to 4.5 chamfered threads makes it appropriate for through-hole threading operations where the tap can pass fully through the workpiece. It is suited for both CNC machining centers and manual tapping setups in industrial and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16-20 UNF thread size with 2B class of fit and H8 thread limit for precise tolerance control\u003c\/li\u003e\n  \u003cli\u003eCobalt high speed steel construction with V-coating for extended tool life in difficult materials\u003c\/li\u003e\n  \u003cli\u003eThread forming design displaces material rather than cutting, eliminating chip evacuation concerns in through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 4 to 4.5 chamfered threads for efficient thread lead-in\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through feature\u003c\/li\u003e\n  \u003cli\u003eCompatible with material application codes P, M, N, and H covering a wide range of ferrous and non-ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading applications in aluminum, cast aluminum, hardened steel, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium workpieces, as specified by material application codes P, M, N, and H.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps should be installed by qualified machinists following proper tap holder alignment procedures to prevent breakage. Always ensure the spindle speed and feed rate are set appropriately for the workpiece material before operation. Power down or lock out any machine before changing or inspecting taps. Do not use thread forming taps in blind holes without confirming adequate material flow clearance, as this tap is rated for through-hole applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4 to 4.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.937 inches (100 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.712 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.693 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.242 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.406 inches\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: 16250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Name\u003c\/strong\u003e: EXOPRO XPF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1625076248\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730228379954,"sku":"1625076248","price":178.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a1414e31a570fbb064964d71eb3551_2dc816ee-2d66-4d87-b89c-babe0475f533.jpg?v=1788713697","url":"https:\/\/voomisupply.com\/products\/osg-1625076248-thread-forming-tap-7-16-20-unf-plug-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
