Built from high speed steel with a bright finish, it cuts a 5\/16-24 UNF right-hand thread with a 2-flute spiral point geometry that pushes chips ahead of the tap and out through the exit side of the workpiece. The H1 thread limit and Class 2B fit make it suited for standard tolerance threaded holes where close control over minor diameter is required. Machinists, tool and die makers, and maintenance technicians install this tap by hand or under power in drill press or CNC applications.\u003c\/p\u003e\u003cp\u003eThis tap is configured for through-hole threading in alloy steel, carbon steel, and aluminum workpieces. The plug chamfer — typically 3 to 5 threads of lead — requires a starter hole and allows entry into a clean through-hole without excessive axial force. The spiral point geometry is particularly efficient in production environments where chip evacuation out the bottom of the hole reduces tap breakage and recutting. Series 1011 designates this as part of Cleveland's standard tap line for general-purpose threading work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward through the hole for clean through-hole threading\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides wear resistance across alloy steel, carbon steel, and aluminum\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (3 to 5 thread lead) for standard through-hole entry\u003c\/li\u003e\n\u003cli\u003eH1 thread limit with Class 2B fit for standard tolerance threaded holes\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating for applications where coating compatibility is a concern\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading operations producing 5\/16-24 UNF Class 2B right-hand threads in alloy steel, aluminum, and carbon steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a tap wrench, drill press, or CNC tapping head with proper alignment to the pre-drilled pilot hole. Power down and secure the workpiece before beginning the tapping operation. Follow ASME B1.1 standards for UNF thread tolerances and confirm pilot hole diameter against standard 2B tap drill charts before starting. Avoid forcing the tap if resistance increases unexpectedly — back out to clear chips and re-inspect the hole.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\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: H1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: 0.690 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.450 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1011\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: C57157\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51692844024114,"sku":"C57157","price":29.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0687dd771c5a943a5462f38dcda4c248_ec231053-9711-4811-975c-c9b35f1c475e.jpg?v=1788303911","url":"https:\/\/voomisupply.com\/products\/cleveland-c57157-spiral-point-tap-5-16-24-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
