Built from high speed steel with a bright, uncoated finish, it delivers consistent thread geometry across both blind-hole and through-hole applications. The plug chamfer configuration — 3 to 5 threads of lead — makes it the standard choice for initiating and completing threads in pre-drilled holes without requiring a starter tap. With 4 flutes and an H3 thread limit, this tap produces Class 2B threads with the clearance needed for plated or coated fasteners. Machinists and tool-and-die professionals reach for the C54814 in production and repair environments alike.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for manual tapping operations in job shops, maintenance facilities, and light manufacturing settings. It handles blind-hole and through-hole threading in alloy steel, carbon steel, aluminum, and free-machining stainless steel. The right-hand thread direction and standard shank geometry make it compatible with conventional tap wrenches and hand-tapping setups. Series 1002 from CLEVELAND represents a workhorse line for general-purpose inch-thread tapping where consistent tolerances and reliable tool life are the primary requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11\/16-11 UNC thread form, right-hand, Class 2B fit with H3 thread limit for controlled oversize tolerance\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) for starting and completing threads in blind or through holes\u003c\/li\u003e\n  \u003cli\u003e4-flute straight-flute geometry for balanced cutting action and chip control in ductile materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across steel, aluminum, and free-machining stainless applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup that could affect thread tolerance in tight-clearance fits\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement — suitable for manual tapping with standard cutting fluid application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for manual hand-tapping operations in alloy steel, carbon steel, aluminum, and free-machining stainless steel workpieces requiring 11\/16-11 UNC internal threads.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed and operated by machinists or maintenance technicians using a standard tap wrench sized to the 0.542-inch shank and 5\/8-inch square drive. Always secure the workpiece and ensure the tap is aligned perpendicular to the drilled hole before applying torque. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Back off periodically during tapping to break chips, especially in blind-hole applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 11\/16-11\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: 11\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\u003eClass of Fit\u003c\/strong\u003e: 2B\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: 4.031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.542 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.406 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.625 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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1002\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: C54814\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698969182514,"sku":"C54814","price":93.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/973cdcc7b13b65a39d6ef3b00d3b0068.jpg?v=1788370500","url":"https:\/\/voomisupply.com\/products\/cleveland-c54814-hand-tap-11-16-11-unc-plug-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
