It is a 4-flute, straight-flute design built for cutting internal threads in a wide range of metal workpieces. The tap measures 2.719 inches overall length with a 0.69-inch thread length and is ground to a Class 2B fit with an H5 thread limit. It is used by machinists, tool-and-die workers, and maintenance tradespeople for hand-tapping operations in both blind and through-hole applications. The right-hand thread direction and plug chamfer make it a standard choice for production and repair threading work.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for both blind hole threading and through-hole threading in a shop or field maintenance setting. It performs in alloy steel, carbon steel, aluminum, and free-machining stainless steel. The plug chamfer provides 3 to 5 chamfered threads, which guides the tap into a pre-drilled hole with moderate starting resistance — a practical balance between a taper and a bottoming tap. It is part of the CLEVELAND Series 1002 hand tap lineup and is packaged individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form, right-hand direction, Class 2B fit\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit for controlled tolerance threading\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute geometry for chip clearance and stability\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across common metal types\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating interference with close-tolerance work\u003c\/li\u003e\n  \u003cli\u003eSuited for both blind hole and through-hole threading applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand-tapping operations in alloy steel, carbon steel, aluminum, and free-machining stainless steel workpieces requiring a 5\/16-18 UNC internal thread.

Always pre-drill the correct tap drill size for 5\/16-18 UNC before starting. Apply cutting oil appropriate for the workpiece material to reduce friction and extend tap life. Back the tap off periodically during threading to break chips, particularly in blind holes.\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\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: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight Flute\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Materials\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: C54512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51709104816434,"sku":"C54512","price":27.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/458745feeceb5c7c97bab89ea486708d.jpg?v=1788451363","url":"https:\/\/voomisupply.com\/products\/cleveland-c54512-hand-tap-5-16-18-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
