Made from high-speed steel (HSS) with a bright, uncoated finish, this tap is built for threading ferrous and non-ferrous materials in standard machining and maintenance applications. The plug chamfer on the lead threads makes it well-suited for through-hole tapping where the tap can pass fully through the workpiece. With 3 flutes and an H2 thread limit, it holds tight dimensional consistency within a 2B and 3B class of fit, meeting common fastener assembly tolerances.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shop, toolroom, and field maintenance environments where left-hand threaded 5-40 fasteners are required. Left-hand taps are typically specified for applications involving counter-rotation assemblies, anti-loosening designs, or replacement of damaged left-hand threaded holes. The 5-40 UNC size is common in small instrument, optical, and precision mechanical assemblies. This tap is appropriate for use in drill presses, CNC machining centers, and manual tapping operations by machinists, tool and die makers, and maintenance technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand thread direction for counter-rotation and anti-loosening applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for through-hole tapping operations\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for consistent 2B and 3B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003e3-flute straight flute geometry for chip clearance in standard tapping\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose use without coating-related dimensional offset\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for any application requiring a 5-40 UNC left-hand internal thread with a plug chamfer and H2 thread limit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists and maintenance technicians using a standard tap wrench, tapping head, or CNC rigid tapping setup. Always drill the correct tap drill size for 5-40 UNC prior to tapping and ensure the workpiece is securely fixtured. Apply appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Left-hand taps require counter-clockwise rotation to cut threads — verify spindle direction before powered operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\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: Left Hand\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 and 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.9375 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0074 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY4945408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701064761650,"sku":"JY4945408","price":21.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b673421a261c529acfdd98ad35daa39a.jpg?v=1788397728","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4945408-5-40-unc-straight-flute-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
