Built from high-speed steel (HSS) with a bright\/uncoated finish, this tap delivers reliable thread-cutting performance in general machining and repair applications. The plug chamfer style — with approximately 3 to 5 chamfered threads at the lead — suits through-holes and moderately deep blind holes where standard entry conditions apply. At 2.375 inches overall length, the tap fits standard tap wrench and machine setups used by machinists, tool-and-die workers, and maintenance technicians working on fine-thread fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations requiring a 10-40 UNS thread form, a less common thread standard used in specialized instrument, optical, and mechanical assembly work. The 4-flute design provides good chip support and thread guidance, making it appropriate for use in hand tapping or light-duty machine tapping on ferrous and non-ferrous metals. Right-hand thread direction matches standard 10-40 UNS fastener orientation. The H2 thread limit designation indicates a controlled pitch diameter tolerance for achieving a 3B class of fit, which is the standard free fit for most commercial threading applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-40 UNS thread form with H2 thread limit for 3B class of fit\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of work materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer lead — approximately 3 to 5 chamfered threads — for versatile through-hole and blind-hole use\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute geometry for stable chip control and consistent thread form\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids in standard tapping operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-cutting tool for 10-40 UNS internal threads in applications requiring a 3B class of fit with H2 thread limit tolerance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists or maintenance technicians using a tap wrench or compatible machine tapping setup. Always ensure the workpiece is properly secured and the pilot hole is drilled to the correct tap drill diameter for a 10-40 UNS thread before tapping. Apply appropriate cutting fluid to reduce heat and extend tool life. Reverse the tap periodically when hand tapping to break chips and prevent binding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\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: 4\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\u003eOverall Length\u003c\/strong\u003e: 2.375 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\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: JY4838405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711698272562,"sku":"JY4838405","price":52.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d3d7764910f8de6ecc7288379bae18c.jpg?v=1788478613","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4838405-straight-flute-tap-10-40-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
