Manufactured from Vanadium High Speed Steel (HSS-E) with a steam oxide coating, it provides improved lubricity and corrosion resistance during cutting. The plug chamfer distributes cutting load over several leading threads for easier entry and reduced torque. With a 1.21-inch thread length and 4.331-inch overall length, it suits standard through-hole tapping operations in both manual and machine setups. This tap is built to an H2 thread limit and a 2B class of fit, delivering consistent thread tolerance across production runs.\u003c\/p\u003e\u003cp\u003eThe OSG 2533801 is suited for threading through-holes in a wide range of ferrous and non-ferrous metals, including aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and cast iron. It is commonly used in machine shops, maintenance and repair operations, and production environments where accurate UNF thread profiles are required. The 3-flute spiral point geometry pushes chips forward ahead of the tap, making it most effective in through-hole applications rather than blind holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-16 UNF thread size with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003e3-flute spiral point design pushes chips ahead during through-hole tapping\u003c\/li\u003e\n\u003cli\u003eVanadium HSS-E construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and improves chip flow\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for general-purpose through-hole starting\u003c\/li\u003e\n\u003cli\u003eH2 thread limit with 2B class of fit for standard tolerance threads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production tap for any application requiring a 3\/4-16 UNF, 2B class of fit, right-hand internal thread in through-hole workpieces. No coolant-through capability; best suited for applications using cutting fluid applied externally.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by licensed machinists or qualified shop technicians using a tap wrench, tapping head, or CNC machine tool spindle. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for a 3\/4-16 UNF thread before beginning. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve thread finish. Do not reverse the tap abruptly without clearing chips, and avoid exceeding the tool's rated torque range to prevent breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.331 inches (110 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.21 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\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel (HSS-E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.342 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Hardened Steel, Stainless Steel, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel, Alloy Steel, Die Steel, Cast Iron\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: 2533801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728655647026,"sku":"2533801","price":134.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aea37d07fd000d7baee2f06f27849f91_f86f78ae-d490-42b0-8fc1-50c68b2b6157.jpg?v=1788694485","url":"https:\/\/voomisupply.com\/products\/osg-2533801-spiral-point-tap-3-4-16-unf-plug-2b-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
