Built from high speed steel with an oxide coating, this plug-chamfer tap handles the full threading sequence in ferrous and stainless materials where hand or machine tapping operations are required. The 4-flute design provides balanced cutting geometry and chip control across a range of workpiece materials. At 3.375 inches overall length with a 0.94-inch thread length, the C56020 fits standard tap wrench drives via its 7\/16-inch square drive and 0.367-inch shank diameter. The H3 thread limit and Class 2B fit specification make it suitable for general-purpose threaded fastener applications.\u003c\/p\u003e\u003cp\u003eThe C56020 is used in job shop, maintenance, and production environments where 1\/2-13 UNC threads must be cut or chased in cast iron, steel, or stainless steel workpieces. The plug chamfer — with its moderate lead — works for starting threads in through-holes or continuing after a taper tap in blind holes. This tap is suited for use by machinists, millwrights, pipefitters, and maintenance mechanics working to standard UNC thread specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread form with Class 2B fit and H3 thread limit for general-purpose fastener compatibility\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide coating for corrosion resistance and lubricity during cutting\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides moderate lead suitable for both through-hole and blind-hole threading\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute geometry for balanced cutting action in ferrous and stainless materials\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, standard for the vast majority of UNC fastener applications\u003c\/li\u003e\n\u003cli\u003eNo coolant-through feature — intended for hand or manual machine tapping with applied cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 1\/2-13 UNC threads in cast iron, stainless steel, and steel workpieces in blind-hole and through-hole applications.

Always apply a cutting fluid appropriate to the workpiece material — particularly when tapping stainless steel — to reduce heat buildup and extend tap life. Back the tap off periodically to break and clear chips, especially in blind-hole applications. Follow shop safety practices and use appropriate personal protective equipment when hand-tapping operations are performed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Drive Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Drive Length\u003c\/strong\u003e: 0.4375 inches\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: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\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: 1002BO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C56020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51735278354738,"sku":"C56020","price":45.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/324f91dde52f70e3cf1ed144855d49cd.jpg?v=1788771424","url":"https:\/\/voomisupply.com\/products\/cleveland-c56020-hand-tap-1-2-13-unc-plug-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
