Built from high speed steel with a bright finish, it features a plug chamfer and 2 flutes, producing clean threads by pushing chips forward through the hole rather than packing them in the flute. The H2 thread limit and Class 2B fit designation make it a standard choice for general-purpose internal threading applications where moderate tolerance is required. Overall length is 1.875 inches with a thread length of 0.310 inches and a shank diameter of 0.141 inches. Licensed machinists, tool and die makers, and maintenance technicians install this tap using a standard tap wrench or machine spindle.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole applications in alloy steel, carbon steel, and aluminum workpieces. The 4-48 UNF designation places it in fine-pitch territory, commonly found in small fastener applications in precision assemblies, electronic enclosures, and instrument hardware. The spiral point geometry is well matched to CNC tapping and manual machine use where chip evacuation ahead of the cutting edge is essential for clean thread formation and tool longevity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward for clean through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness and wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 2 flutes balances cutting action and chip clearance\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit with Class 2B fit for general-purpose tolerance requirements\u003c\/li\u003e\n  \u003cli\u003eBright finish with no coating for straightforward inspection and resharpening\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tap handles and CNC spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, and carbon steel workpieces requiring a 4-48 UNF internal thread.

Always use appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Ensure the workpiece is properly secured and the tap is started perpendicular to the hole to avoid thread distortion or tap breakage. Spiral point taps require a through hole with adequate clearance beyond the full thread depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 48\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 Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.310 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches (3.58 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.260 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 2.79 mm\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\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon 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: 1011\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C57051\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51707284390194,"sku":"C57051","price":28.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93ce0faf41a0689be39f29cff31850b6.jpg?v=1788439391","url":"https:\/\/voomisupply.com\/products\/cleveland-c57051-spiral-point-tap-4-48-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
