Built from high speed steel with a bright uncoated finish, this tap features a taper chamfer that guides the tool into the workpiece gradually, reducing the force required to start the thread. Four flutes provide chip clearance and cutting efficiency. With an overall length of 2.719 inches and a thread length of 0.69 inches, the C54504 is sized for bench-top and machine tapping operations performed by machinists, tool-and-die makers, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis tap is suited for both blind-hole and through-hole threading applications in production and repair environments. The 3B class of fit and H3 thread limit make it appropriate for standard tolerance internal threads. Compatible material applications include alloy steel, carbon steel, aluminum, and free-machining stainless steel, making it a versatile choice for job shops and maintenance departments working across multiple material types.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC thread size with taper chamfer for progressive thread engagement\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 suitable for general-purpose threading with cutting fluids\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute geometry supports chip evacuation in blind and through holes\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and 3B class of fit for standard tolerance internal threads\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, Series 1001\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind-hole and through-hole threading in alloy steel, carbon steel, aluminum, and free-machining stainless steel.

Always apply an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Ensure the workpiece is securely fixtured and the tap is started perpendicular to the workpiece surface to avoid cross-threading or breakage. Back the tap out periodically to break and clear chips, especially in blind-hole applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.719 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 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\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: 1001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C54504\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51712711819570,"sku":"C54504","price":25.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d4c7b34d43181ba7a0559bb94e80e42.jpg?v=1788488116","url":"https:\/\/voomisupply.com\/products\/cleveland-c54504-hand-tap-5-16-18-unc-taper-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
