Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tap is suited for general-purpose threading in softer metals, plastics, and non-ferrous materials. It features a plug chamfer with 3 to 5 lead threads to ease starting, 3 flutes for adequate chip clearance, and an H2 thread limit for a standard tolerance fit. Overall length is 1-7\/8 inches with a thread length of 9\/16 inches. Machinists, tool-and-die workers, and maintenance technicians install this tap in manual or low-speed CNC applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for right-hand 4-40 UNC threading operations in production and repair environments. The plug chamfer makes it appropriate for through-hole applications as well as blind holes with sufficient relief at the bottom. The 2B and 3B class of fit covers standard commercial threads through tight-tolerance fastener applications. It is commonly used in light assembly, instrument fabrication, and general machine shop work where a 4-40 threaded hole is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread form with right-hand direction for standard fastener compatibility\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3 to 5 lead threads) for easy tap starting in through-holes and blind holes with relief\u003c\/li\u003e\n  \u003cli\u003e3 flutes provide balanced chip clearance in general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit supports 2B and 3B class of fit for standard and close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction delivers durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids or dry tapping in softer materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose straight flute tap for cutting 4-40 UNC internal threads in standard tapping applications.

Always secure the workpiece and use a tapping fluid appropriate for the workpiece material to extend tool life and improve thread quality. Ensure the tap is properly aligned before applying cutting pressure to avoid tap breakage, particularly in small-diameter applications like 4-40. Back off periodically to break chips, and never force a tap that meets unexpected resistance.\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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 Length\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1-7\/8 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\u003eCoating\/Finish\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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-04424404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720354726194,"sku":"MSC-04424404","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc18492e1e85733bac40ec87fd0b04f2.jpg?v=1788562700","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04424404-straight-flute-tap-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
