Built from high-speed steel, it produces 2-56 UNC threads to a 2B class of fit with an H2 thread limit, ensuring consistent thread form and dimensional accuracy. The plug chamfer provides a gradual lead-in that works well in through-hole tapping. With a thread length of 7\/16 inches and an overall length of 1-3\/4 inches, this tap fits standard tap wrenches, T-handle drivers, and machine tool holders used in precision threading work.\u003c\/p\u003e\u003cp\u003eThis tap is suited for thread-cutting operations in ferrous and non-ferrous materials across light manufacturing, repair shops, and tool room environments. Its 2-56 UNC configuration is common in small fastener applications including instrument assembly, electronics enclosures, and precision mechanical components. The two-flute straight design provides chip clearance in both through-hole and short blind-hole situations, though it is most effective in through-hole applications where chips can exit freely.\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 fastener compatibility\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for controlled tolerance threading\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with gradual lead-in suitable for through-hole tapping\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides wear resistance across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eTwo-flute straight design promotes chip clearance during operation\u003c\/li\u003e\n\u003cli\u003eCompact 1-3\/4 inch overall length fits standard small tap holders and machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces.

Ensure the correct tap drill diameter is used for 2-56 UNC before starting. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Do not force the tap if resistance increases abnormally, as breakage in small-diameter taps is difficult to reverse.\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\u003eThread Limit\u003c\/strong\u003e: H2\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\u003eThread Length\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\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: 102\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: 1065102\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743999721778,"sku":"1065102","price":33.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69617f68a9b797c05d9d8c137f12ad0f.jpg?v=1788852658","url":"https:\/\/voomisupply.com\/products\/osg-1065102-straight-flute-plug-tap-2-56-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
