Built from high-speed steel (HSS) with a bright, uncoated finish, it runs a 4-flute, plug-chamfer geometry that balances thread-starting ease with cutting efficiency. The plug chamfer provides a gradual lead-in, making it suitable for both blind-hole and through-hole threading operations. At 5.125 inches overall length with a 2.5-inch thread length, this tap is sized for production and maintenance threading tasks handled by machinists, toolmakers, and skilled tradespeople working in machine shops or field maintenance environments.\u003c\/p\u003e\u003cp\u003eThis tap is intended for threading operations in alloy steel, aluminum, carbon steel, and free-machining stainless steel. Its 3B class of fit and H4 thread limit deliver a controlled tolerance suitable for standard fastener engagement. The right-hand, 1-12 UNF thread form is common in precision mechanical assemblies, automotive components, and industrial equipment where fine-pitch threads are required. It is part of Cleveland Series 1002 and is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePlug chamfer geometry supports both blind-hole and through-hole threading\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute design for efficient chip handling in a range of metals\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across common ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish maintains consistent tool dimensions for precise H4 thread limit tolerance\u003c\/li\u003e\n\u003cli\u003e3B class of fit suits standard threaded fastener assemblies\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, 1-12 UNF thread form for fine-pitch applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for threading alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces requiring a 1-12 UNF internal thread at a 3B class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists or maintenance technicians using a standard tap wrench or appropriate machine holder. Always ensure the workpiece is securely fixtured before threading. Apply cutting fluid appropriate for the workpiece material to reduce tool wear and improve thread finish. For blind-hole applications, verify hole depth provides adequate clearance beyond the intended thread length before tapping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-12\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: 12\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\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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\u003eOverall Length\u003c\/strong\u003e: 5.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.8125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.600 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 1.15 pounds\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: C54929\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699985252658,"sku":"C54929","price":191.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49a133db8bca06b265fb1dcb97b89308.jpg?v=1788384528","url":"https:\/\/voomisupply.com\/products\/cleveland-c54929-hand-tap-1-12-unf-plug-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
