With 2 flutes and a plug chamfer, this tap pushes chips ahead of the cut, keeping the flutes clear and reducing the risk of chip packing in production or maintenance drilling operations. The tap is manufactured from high-speed steel (HSS) with a bright finish and conforms to a 2B class of fit, which is the standard tolerance range for general-purpose threaded fastener assemblies. At 1.75 inches overall length with a 0.437-inch thread length, it fits standard tap handles and machine tap holders for #2-56 work.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading small-diameter through-holes in light manufacturing, instrument assembly, electronics enclosures, and general machining where 2-56 UNC fasteners are used. Rated material applications include aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. It is a practical choice for both manual tapping operations and low-speed machine tapping where through-hole thread cutting at a fine pitch is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-56 UNC thread form with 2B class of fit for standard general-purpose fastener tolerance\u003c\/li\u003e\n\u003cli\u003eSpiral point design pushes chips forward, suitable for through-hole tapping\u003c\/li\u003e\n\u003cli\u003e2 flutes with plug chamfer for gradual thread engagement and reduced tap breakage risk\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides good wear resistance in aluminum and low-to-medium carbon steel\u003c\/li\u003e\n\u003cli\u003eBright finish, no coating — allows direct visual inspection of tool condition\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for threading 2-56 UNC through-holes in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel workpieces.

Always secure the workpiece and ensure the tap is started perpendicular to the hole to avoid thread misalignment or tap breakage. Apply an appropriate cutting fluid for the workpiece material before and during tapping. At the 2-56 size, tap breakage risk is elevated — avoid excessive force and back the tap out periodically to clear chips even in through-hole work.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.437 inches (7\/16 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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\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: 2884400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732174274866,"sku":"2884400","price":31.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4fb4a698ca85c23e3cf855d2f44b16e.jpg?v=1788740045","url":"https:\/\/voomisupply.com\/products\/osg-2884400-spiral-point-tap-2-56-unc-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
