Built from high-speed steel (HSS) with a bright\/uncoated finish, it is suited for hand or machine tapping operations where a standard insert-sized thread form is required. The tap features 2 flutes and a plug chamfer for through-hole applications. Overall length is 1.882 inches, with a shank diameter of 0.141 inches. This tool belongs to OSG Series 11036 and carries a 2B class of fit with an H2 thread limit, making it appropriate for general-purpose threaded insert work at the 2-56 UNC size.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in light machining, maintenance, and repair applications where STI (Screw Thread Insert) threads are needed to accept a helical insert, restoring or creating a stronger threaded hole. It is appropriate for use in machine shops, aerospace maintenance, and general industrial settings. The plug chamfer style makes it best suited for through-hole tapping. Machinists, toolmakers, and maintenance technicians are the primary users of this tap size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSTI spiral point design drives chips forward, suited for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003e2-56 UNC thread form for screw thread insert applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit with 2B class of fit for consistent insert-ready thread geometry\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1.882 inches suits confined tapping environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style STI tap for use with standard 2-56 UNC helical thread inserts in through-hole tapping applications across general industrial and maintenance repair operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by a machinist or maintenance technician using a standard tap wrench or machine tapping setup. Ensure the workpiece is securely clamped and properly aligned before tapping. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Do not force the tap if resistance increases — back off to clear chips before continuing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\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\u003eOverall Length\u003c\/strong\u003e: 1.882 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.295 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 11036\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.4 x 0.4 x 0.35 inches\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: 1103600100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754410246450,"sku":"1103600100","price":67.02,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/osg-1103600100-spiral-point-sti-tap-2-56-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
