Manufactured from high speed steel with a bright\/uncoated finish, this tap is built for general-purpose hand and machine tapping where cutting fluid is applied externally. The plug chamfer — typically 3 to 5 threads — provides a balance between starting ease and thread engagement, making it suitable for a wide range of production and maintenance threading tasks. The H11 thread limit indicates an oversize condition of 0.0050 inches, which is factored in for plated or close-tolerance thread requirements.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in metalworking and maintenance applications across manufacturing, mechanical contracting, and industrial service environments. It is rated for threading in alloy steel, aluminum, carbon steel, and free-machining stainless steel. The plug style is the most common tap used in general shop work, appropriate for both through-holes and blind holes with adequate chip clearance. Thread length runs 0.6900 inches, and overall length is 2-23\/32 inches, making it compatible with standard tap holders and floating tap chucks used in drill press or CNC tapping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form with plug chamfer for versatile blind and through-hole use\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip evacuation in ductile and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for general-purpose machine and hand tapping\u003c\/li\u003e\n  \u003cli\u003eH11 thread limit with 0.0050 inch oversize for plating allowance or close-fit thread control\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — compatible with most cutting oils and tapping fluids\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 5\/16-18 UNC internal threads in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces.

Before tapping, ensure the correct drill size for 5\/16-18 UNC threads is used and the workpiece is securely fixtured. Apply appropriate cutting fluid for the workpiece material throughout the tapping operation. Inspect the tap for wear or chipping before each use and never force a tap that has stalled in the hole.\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\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\u003eThread Limit\u003c\/strong\u003e: H11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmount Oversize\u003c\/strong\u003e: 0.0050 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.6900 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-23\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.2380 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\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\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: C54514\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51721731801394,"sku":"C54514","price":30.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/670f230d468c80160ad668fbae1439da.jpg?v=1788580027","url":"https:\/\/voomisupply.com\/products\/cleveland-c54514-straight-flute-tap-5-16-18-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
