Built from high speed steel (HSS) with a bright uncoated finish, this tap delivers consistent thread quality in both blind-hole and through-hole applications. The plug chamfer geometry features a moderate lead-in that balances chip clearance with thread-starting control. Overall length is 2.719 inches with a thread length of 0.690 inches. The 2-flute straight-flute design suits hand tapping operations where controlled torque and chip management are critical to achieving a clean Class 3B fit.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for job shop, maintenance, and production environments where hand tapping 5\/16-18 UNC threads is required. The H3 thread limit keeps finished thread dimensions within tolerance for standard Class 3B fits, making it appropriate for fastener assemblies and precision threaded connections. Typical applications include fabrication of alloy steel components, aluminum assemblies, carbon steel structures, and free-machining stainless steel parts. It is commonly used by machinists, millwrights, and maintenance technicians working with standard UNC fastener threads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form, right-hand cut, Class 3B fit\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent tolerance control across production runs\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with moderate lead-in suits both blind-hole and through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread dimensions\u003c\/li\u003e\n  \u003cli\u003e2-flute straight-flute design optimized for hand tapping with standard tap wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces.

Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for 5\/16-18 UNC threads before beginning. Apply cutting fluid appropriate to the workpiece material to reduce friction and extend tool life. Back the tap out periodically to break chips, particularly in blind-hole applications, to prevent tap breakage.\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 UNC\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: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: C54507\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51718858637618,"sku":"C54507","price":30.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd30539746fc0eae772ecd008e33114f.jpg?v=1788556023","url":"https:\/\/voomisupply.com\/products\/cleveland-c54507-hand-tap-5-16-18-unc-plug-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
