Built from high speed steel (HSS) with a bright uncoated finish, this plug-chamfer tap drives chips forward ahead of the cutting edge, making it well-suited for use in production and repair threading operations. It features 2 flutes, a right-hand thread direction, and an H2 thread limit, which controls the tolerance of the finished thread to ensure consistent 2B and 3B class of fit results. The 9\/16 inch thread length provides adequate engagement for most standard fastener depths in this size range.\u003c\/p\u003e\u003cp\u003eThis tap is used in light-duty threading applications where 4-40 UNC threads are required in through-holes. It is appropriate for use in metal fabrication, machine shops, electronics assembly, and general maintenance environments. The plug chamfer style makes it the standard choice for starting in a pre-drilled through-hole and completing the thread in a single pass. Machinists, tool and die makers, and maintenance technicians regularly work with taps in this configuration for small-diameter threading tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC thread specification for fine-pitch small-diameter through-hole threading\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability across a range of work materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer style for standard through-hole starting and thread completion\u003c\/li\u003e\n\u003cli\u003e2 flutes with forward chip ejection suited to spiral point design\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for consistent 2B\/3B class of fit tolerance control\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, bright uncoated finish, no coolant-through required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production tap for applications requiring 4-40 UNC right-hand internal threads in through-hole configurations with a 2B or 3B class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists or maintenance technicians using a tap wrench, tapping head, or CNC tapping cycle. Always start with the correct tap drill size for 4-40 UNC to ensure proper thread engagement and avoid tap breakage. Secure the workpiece and align the tap perpendicular to the drilled hole before applying cutting pressure. Use an appropriate cutting fluid for the work material to extend tap life and improve thread finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\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\u003eThread Length\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC-04504403\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706257473842,"sku":"MSC-04504403","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c42580372e886fe2193fe71259cc0f6.jpg?v=1788433538","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04504403-spiral-point-tap-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
