It produces a 5\/16-18 UNC thread profile using a 2-flute, plug chamfer geometry that pushes chips forward ahead of the cut, keeping the flutes clear during operation. Manufactured from high speed steel with an oxide finish, this tap is built for use in ferrous materials where moderate heat and wear resistance are required. It carries a Class 2B thread fit and an H3 thread limit, making it a standard choice for general-purpose fastener threads in production and maintenance work. Licensed machinists and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading operations in cast iron and steel workpieces. The plug chamfer distributes the cutting load over several leading threads, making it appropriate for both hand tapping and machine tapping setups. With an overall length of 2.719 inches and a thread length of 1.125 inches, it fits standard tap holders and floating tap chucks used in drill press, CNC, and turret lathe applications. The right-hand thread direction is consistent with standard UNC fastener systems used across industrial, automotive, and structural fabrication environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form with Class 2B fit and H3 thread limit for standard fastener clearances\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, reducing clogging in through-hole operations\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability in cast iron and steel applications\u003c\/li\u003e\n  \u003cli\u003eOxide finish offers mild corrosion resistance and break-in lubricity\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 2 flutes balances cutting speed and chip control\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard UNC fastener systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in cast iron and steel.

Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for a 5\/16-18 UNC thread before starting. Apply a suitable cutting fluid rated for the workpiece material to extend tap life and improve thread quality. Do not reverse the tap under power without confirming the machine setup supports reversing cycles, and replace worn taps before continuing production to avoid thread damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Steel\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: Oxide\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: 1.125 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1011BO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 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: C57624\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51713277362482,"sku":"C57624","price":26.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fec7ce4cef5e3cb6fa66833532e67304_f35457c6-f935-43f3-a6ce-38a8da4db67b.jpg?v=1788492485","url":"https:\/\/voomisupply.com\/products\/cleveland-c57624-spiral-point-tap-5-16-18-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
