It cuts a 4-40 UNC thread profile with a 2-flute, plug chamfer geometry that pushes chips forward ahead of the tap, keeping the flutes clear and reducing the risk of chip packing in production or maintenance tapping operations. Built from high speed steel with a bright finish, the C57048 handles moderate-speed tapping in alloy steel, carbon steel, and aluminum. The H2 thread limit keeps finished threads within a tight tolerance band suitable for Class 2B and 3B fits. Overall length is 1.875 inches with a thread length of 0.31 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for light-duty through-hole applications in machine shops, maintenance and repair operations, and field fabrication work. The 4-40 UNC size is common in instrument panels, electrical enclosures, small fastener assemblies, and precision sheet metal work. The plug chamfer makes it the standard choice when threading through a complete hole rather than a blind bore. It is typically driven by a tap wrench, T-handle, or CNC\/manual tapping head at appropriate RPM for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread profile with 40 threads per inch for fine-fastener applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer geometry pushes chips forward, ideal for through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides good wear resistance across common metals\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit ensures compatibility with Class 2B and 3B fit requirements\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, bright finish, no coolant-through requirement\u003c\/li\u003e\n  \u003cli\u003eCompact 1.875-inch overall length fits standard tap holders and wrench drives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in alloy steel, carbon steel, and aluminum workpieces requiring a 4-40 UNC thread.

Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Use consistent, controlled feed pressure to avoid tap breakage, especially in harder alloys. Follow shop safety practices and applicable machine guarding requirements when using powered tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 40\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\/3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\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: 0.31 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\u003eNeck Length\u003c\/strong\u003e: 0.26 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\u003eSeries\u003c\/strong\u003e: 1011\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: C57048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51696646652210,"sku":"C57048","price":25.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3c1c478e978363a3a8c97c03b5b2aeb.jpg?v=1788344761","url":"https:\/\/voomisupply.com\/products\/cleveland-c57048-spiral-point-tap-4-40-unc-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
