Each tap is machined from high-speed steel (HSS) with a bright, uncoated finish. The set covers the standard progression used to thread a hole from start to finish. At 1-7\/8 inches overall length with a 9\/16-inch thread length, these taps are sized for small-fastener work common in precision machining, electronics enclosures, and instrument assembly. The H2 thread limit designation indicates a controlled tolerance suitable for general-purpose threading with standard 4-40 hardware.\u003c\/p\u003e\n\u003cp\u003eThis tap set is used wherever a 4-40 UNC threaded hole is required in ferrous and non-ferrous metals, plastics, and similar machinable materials. Typical applications include light-duty machine assembly, electrical panel fabrication, PCB standoff installation, and repair work on existing 4-40 threads. The 3-flute geometry provides a balance of chip clearance and thread-wall support suited to through-holes and shallow blind holes at this small diameter. Machinists, tool-and-die workers, and maintenance technicians working in job shop or production environments are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread standard, right-hand direction\u003c\/li\u003e\n  \u003cli\u003e3-piece set covering full tap progression for start-to-finish threading\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for visual inspection and general-purpose use\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for controlled tolerance compatible with standard 4-40 fasteners\u003c\/li\u003e\n  \u003cli\u003eCompact 1-7\/8-inch overall length suits benchtop and machine-mounted applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or supplemental tap set for any application requiring 4-40 UNC right-hand internal threads in standard machinable materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTapping should be performed by a machinist or qualified technician using a properly sized tap wrench or tapping head. Always use the appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Ensure the tap is started square to the hole to prevent thread damage or tap breakage, which is a common failure point at small diameters like 4-40. Follow applicable shop safety practices when using cutting tools in powered or manual 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\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePieces in Set\u003c\/strong\u003e: 3\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-04424438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702494855474,"sku":"MSC-04424438","price":25.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a28a515ff7d7a30bc5500b5b7f828a7.jpg?v=1788411471","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04424438-tap-set-4-40-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
