Manufactured from high speed steel with a bright uncoated finish, it delivers reliable thread cutting performance in a compact form suited to small-diameter work. The bottoming chamfer allows threading close to the bottom of a blind hole, making it the go-to choice when full thread depth is required. With a 2-flute straight-flute geometry and a right-hand thread direction, this tap is a standard production and repair tool used by machinists, maintenance technicians, and toolroom professionals.\u003c\/p\u003e\n\u003cp\u003eThis tap is sized for 5-40 UNC threads, a common fastener specification found in precision assemblies, instrumentation, electronics enclosures, and light mechanical hardware. It suits both blind hole and through-hole threading applications. The H2 thread limit holds tight tolerance for Class 2B and 3B thread fits, making it appropriate for general-purpose fastener applications where standard clearance is acceptable. It is used in manual tapping operations with a tap wrench or tapping handle on the bench or in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading to the bottom of blind holes\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 general-purpose use without added coating friction\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for Class 2B and 3B thread fit compliance\u003c\/li\u003e\n  \u003cli\u003e2-flute straight-flute design for straightforward manual tapping\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, standard for most fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces.

Ensure the workpiece is securely fixtured before tapping to prevent tap breakage. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Inspect the tap for wear or chipping before each use; a damaged tap can destroy a blind-hole workpiece that has no room for error.\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: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\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\u003eThreads per Inch\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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\u003eOverall Length\u003c\/strong\u003e: 1.938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Free-Machining Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1003\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C54187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693896794418,"sku":"C54187","price":26.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd20c496d0810452f31c5a367f3d6a0e.jpg?v=1788318721","url":"https:\/\/voomisupply.com\/products\/cleveland-c54187-hand-tap-5-40-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
